There may be.

  FIG. 1 is a schematic diagram showing an outline of a safety judgment system according to the present invention. In the figure, 1 is a mobile phone as an information processing device, 3 is a second authentication device (hereinafter referred to as a certificate authority server) of a certification authority that is in a third party position for issuing an electronic certificate, and 2 is a safety decision authority A central server 4 serving as a first authentication device for determining the safety of the mobile phone 1 is a store computer (hereinafter referred to as a Web server) of an online shop that performs online product sales processing. The cellular phone 1 is connected to a communication network (hereinafter referred to as the Internet) N via a cellular phone network (not shown). Similarly, the certification authority server 3, the central server 2, and the Web server 4 are also connected to the Internet N. Yes. The cellular phone 1 is provided with a fingerprint acquisition unit 112 as biometric information receiving means, and has a function of scanning a customer's fingerprint and taking it into the cellular phone 1.

  FIG. 2 is a block diagram showing a hardware configuration of the mobile phone 1. A cellular phone 1 as an information processing device includes a cellular phone engine unit 110 that performs normal functions such as communication, text, and image data transmission / reception, and a safety determination device 5 according to the present invention. In the present embodiment, a safety determination device (hereinafter referred to as a security chip) 5 is an LSI (Large Scale Integrated Circuit) chip and is mounted inside the mobile phone 1.

  The hardware configuration of the mobile phone engine unit 110 will be described below. As shown in the figure, a CPU (Central Processing Unit) 11 includes a RAM 12, a ROM 15, an antenna unit 16, a power supply unit 113, a microphone / speaker 111, an AD / DA 20, an external connection terminal 19, and a data display via a bus 17. A display unit 14 such as a liquid crystal display and an input unit 13 composed of numeric keys, cursor keys, selection confirmation keys, and the like are connected. The CPU 11 is connected to the above-described hardware units of the mobile phone 1 via the bus 17 and controls them, and executes various software functions according to the control program 15P stored in the ROM 15.

  The external connection terminal 19 is an interface having 16 cores, for example, and is connected to a personal computer (not shown) or a peripheral device via a USB cable or the like. The RAM 12 is configured by an SRAM (Static Random Access Memory), a flash memory, or the like, and stores temporary data generated when the software is executed. The ROM 15 is composed of, for example, an EEPROM (Electrically Erasable and Programmable ROM), etc., and an OS (Operating System) that provides a basic operating environment of the mobile phone 1, a BIOS (Basic) that controls peripheral devices connected to the external connection terminal 19, etc. Input / Output System) and downloaded or preinstalled software such as Java (registered trademark) are stored.

  Apart from the input unit 13 of the mobile phone engine unit 110, a fingerprint acquisition unit 112 that acquires a customer's fingerprint is provided in the vicinity of the input unit 13 of the mobile phone 1. The fingerprint acquisition unit 112 outputs the scanned fingerprint information to the security chip 5. In the present embodiment, fingerprints are used as biometric information. However, the present invention is not limited to this, and information such as voice, retina, or iris may be used. For example, in the case of voice, the voice is obtained from the microphone / speaker 111, the voice is converted into an electrical signal using the AD / DA 20, output to the CPU 11, and authenticated by comparing with the voice data of the customer stored in advance. I do.

  Next, the hardware configuration of the security chip 5 will be described. The security chip 5 includes a microprocessor (hereinafter referred to as MPU) 51, a RAM 52, and a ROM 55 such as an EEPROM. The MPU 51 is connected to the RAM 52 and the ROM 55 described above via the bus 57, and controls them, and executes various software functions according to a control program 55P stored in the ROM 55. The ROM 55 stores an electronic certificate file 553 that stores an electronic certificate received from the certification authority server 3, a personal key file 554 that stores the personal key of the mobile phone 1 itself, and a fingerprint information file 552 that stores customer fingerprint information in advance. And an environment information file 551 storing the device name / version of the mobile phone 1, the device name / version of the peripheral device, the software name / version of the installed software, and the like. The personal key of the mobile phone 1 is issued by the certification authority server 3, and the public key of the mobile phone 1 that is paired with this personal key is managed by the certification authority server 3.

  The MPU 51 of the security chip 5 collects environment information of the mobile phone 1 and stores the environment information in the environment information file 551. The MPU 51 acquires the device name / version of the mobile phone 1 stored in advance from the ROM 15 and acquires information on the mobile phone 1 itself. For example, when the information processing device is a mobile phone, the device name / version is acquired. When the information processing device is a microwave oven, the manufacturer name, the device name, the model number, and the like are acquired. Also, the MPU 51 refers to the BIOS of the ROM 15 to acquire information on the device connected to the external connection terminal 19 and store it in the environment information file 551 as one piece of environment information. For example, when a computer (not shown) is connected to the external connection terminal 19, the device name of the computer is acquired. When the information processing apparatus is a personal computer and the PC card is connected to the PC card slot as the external connection terminal 19, the device name of the PC card is acquired.

  The environment information further includes information on software installed in the mobile phone 1. The MPU 51 refers to the OS and software in the ROM 15 and acquires the name and version of the installed software. For example, when the information processing apparatus is a personal computer, environment information such as Windows (registered trademark) or Linux as the name of the OS and second edition as the version is acquired, and Internet Explorer (registered trademark) of the browser is installed as installed software. Information such as SP2 is acquired as the version. In addition, the name of software described in Java (registered trademark) downloaded through the Internet N is applicable. In this way, the MPU 51 constantly monitors the BIOS, OS, etc. in the ROM, and when new software is installed or when a new device is connected to the external connection terminal 19, such information is stored as environmental information. Collected and stored in the environment information file 551.

  The fingerprint information file 552 is used for personal authentication. For example, when the mobile phone 1 is purchased, a customer's fingerprint is acquired at a store and initially registered in the fingerprint information file 552 in the ROM 55. When the fingerprint information is read and output from the fingerprint acquisition unit 112, the MPU 51 compares the output fingerprint information with the fingerprint information stored in the fingerprint information file 552, and determines whether or not it is appropriate. In the present embodiment, the fingerprint information file 552 used for authentication is provided in the cellular phone 1, but the present invention is not limited to this, and the fingerprint information file 552 is provided in the central server 2 or the certification authority server 3 or the like. Authentication may be performed by the engine server 3 or the like. In this case, the fingerprint information encrypted with the personal key of the personal key file 554 is transmitted to the central server 2 or the certification authority server 3 together with the electronic certificate for authentication.

  The electronic certificate file 553 stores an electronic certificate issued from the certification authority server 3, and the personal key file 554 also contains a personal key for the cellular phone 1 issued from the certification authority server 3. It is remembered. The public key for the mobile phone 1 is stored in the certification authority server 3. The MPU 51 encrypts the data relating to the commercial transaction to be transmitted / received, the environment information, the fingerprint information, etc. with the message digest together with the personal key, and transmits the encrypted data and the electronic certificate to the central server 2 etc. via the Internet N.

  FIG. 3 is a block diagram showing a hardware configuration of the central server 2. As shown in the figure, a CPU (Central Processing Unit) 21 is a gateway for transmitting and receiving information to and from a RAM 22, a storage unit 25 such as a hard disk, a mobile phone 1, a certification authority server 3 and a Web server 4 via a bus 27. A communication unit 26 such as a LAN card, a display unit 24 such as a liquid crystal display, and an input unit 23 such as a keyboard and a mouse are connected. The CPU 21 is connected to the above-described hardware units of the central server 2 via the bus 27, controls them, and executes various software functions according to the control program 25P stored in the storage unit 25. To do. The storage unit 25 is provided with an environmental information database (hereinafter referred to as an environmental information DB) 251 in which environmental conditions are stored in accordance with the safety class of information transmitted and received.

  FIG. 4 is an explanatory diagram showing a record layout of the environment information DB 251. As shown in the figure, environmental information conditions are stored according to the class. The class field is classified into 1 to 6 according to the importance of the safety of information transmitted and received, and class 1 indicates the highest level of safety and class 6 indicates that the level of safety is the lowest. . As shown in the amount information field and the product information field, if the transaction is a small amount of about 100 yen or the product is a low-priced product such as a ringtone (hereinafter called ringtone), a smoother transaction than safety The class is set to 6 because it needs to be emphasized. On the other hand, in the case of a transaction of a high-priced product of 50000 yen or more, if the product is a stock certificate or the like, the class is set to 1 because it is necessary to ensure high safety.

  In the device information field in the environmental condition field, the device name / version of the customer's mobile phone 1 is stored in association with the class. For example, in the case of the class 1, it is a condition that the mobile phone 1 is the latest model S004, F004, and N004. Unless the condition is satisfied as environmental information, it is not determined to be appropriate in environmental authentication. In particular, for S004, the version of the mobile phone 1 is also 2.0 or more. On the other hand, in the case of class 6, in addition to S001 which is an old model, in addition to S001, S002, S003 and S004, similarly, it is determined that the cellular phone 1 of F001 to F004 and N001 to N004 is appropriate. .

  Similarly, in the peripheral device field, the device name and version of the peripheral device are stored for each class, and are used for environment authentication. For example, in the case of class 6, even if peripheral devices XX, XY, etc. are connected, it is determined as appropriate in environmental authentication. On the other hand, in the case of class 1, the condition of the corresponding peripheral device is not stored, and if the peripheral device information is transmitted from the mobile phone 1 as the environmental information, it is not determined to be appropriate. That is, in the case of class 1, it is determined that the environment authentication is inappropriate even if any peripheral device is connected. These pieces of information store information provided by each vendor.

  Similarly, the software field stores the software name and version according to the class. Class 1 is software C, and it is determined to be appropriate when the version is 3.0 or higher. On the other hand, in the case of class 6, if it is software C and the version is 1.0 or more, it is determined to be appropriate. The reason why safety is determined by providing a class in this way is in consideration of the balance between smooth business transactions and maintenance of safety. For example, when the information processing apparatus is a personal computer, the installed browser differs depending on the customer. For example, in Internet Explorer (registered trademark) of Microsoft (registered trademark), there are a plurality of versions, and the number of security holes decreases as the version increases.

  If a high level of safety is required, it may be possible to obtain environmental information, determine that it is appropriate only if the browser is the latest version without security holes, and allow subsequent commercial transactions. Then, customers who don't have the latest version will not be able to do business at all and lack validity. Therefore, if it is a low-priced product that does not require much safety, the authentication class will be lowered, and even if the browser is a little older, it will be judged to be appropriate under certain conditions and allow commercial transactions. .

  With the above hardware configuration, the safety judgment processing procedure according to the present invention will be described with reference to a flowchart. FIG. 5 is a flowchart showing the procedure of the commercial transaction between the Web server 4 and the mobile phone 1. First, the URL (Uniform Resource Locator) of the Web server 4 of the online shop that conducts the commercial transaction is input to the input unit 13 of the mobile phone 1, and an acquisition request for the product ordering page is made to the Web server 4 (step S51). The Web server 4 as an HTTP (Hypertext Transfer Protocol) server reads a corresponding cHTML (compact hypertext markup language) file from a storage unit (not shown) (step S52), and transmits the read cHTML file to the mobile phone 1 (step S53). .

  The CPU 11 of the mobile phone 1 analyzes the received cHTML using browser software stored in the ROM 15 and displays a Web page for commerce as shown in FIG. 6 (step S54). FIG. 6 is an explanatory diagram showing an image of a Web page. As shown in the figure, the display unit 14 displays information about the product to be ordered, quantity, and amount. The customer operates the input unit 13 to select the product and quantity to be ordered. When the product is selected, the CPU 11 executes the Java script transmitted at the same time as the cHTML file, calculates the total amount, and displays it. The online shop in the present embodiment sells computer-related devices such as personal computers, printers, disk drives, etc., and shows that a customer orders one 29800 yen inkjet printer. That is, the customer inputs money amount information or product information as order information related to the commercial transaction. In addition, an address, a telephone number, a name, an ID, a password, and the like may be input.

  In this way, order information is input from the input unit 13, and the CPU 11 accepts the order information (step S55). Then, when the “Place Order” button shown in FIG. 6 is selected, the process proceeds to a safety determination process (step S56). The processing after step S57 will be described later. Hereinafter, a subroutine of the safety determination process that is a feature of the present invention will be described with reference to a flowchart.

  7 to 12 are flowcharts showing the procedure of the safety judgment process. When the order information is input, the MPU 51 of the security chip 5 executes the control program 55P and displays a fingerprint information acquisition request on the display unit 14 (step S71). The contents to be displayed are stored in the ROM 55 in advance. For example, information such as “Put your thumb on the fingerprint acquisition unit” may be read and output to the display unit 14. When fingerprint information is input from the fingerprint acquisition unit 112, the MPU 51 of the security chip 5 receives the fingerprint information (step S72) and temporarily stores it in the RAM 52. Then, the MPU 51 reads the fingerprint information stored in advance in the fingerprint information file 552 of the ROM 55 at the time of purchase of the mobile phone 1 and compares it with the fingerprint information stored in the RAM 52, that is, the fingerprint information authentication is appropriate. It is determined whether or not there is (step S73).

  If the fingerprints match and it is determined that fingerprint information authentication is appropriate (YES in step S73), a fingerprint authentication appropriate flag is set, and the set fingerprint authentication appropriate flag is transmitted to the central server 2 (step S75). On the other hand, if the fingerprints do not match and it is determined that fingerprint information authentication is inappropriate (NO in step S73), the fingerprint authentication inappropriate flag is set, and the set fingerprint authentication inappropriate flag is transmitted to the central server 2. (Step S74). The CPU 21 of the central server 2 stores the transmitted fingerprint authentication flag (fingerprint authentication appropriate flag or fingerprint authentication inappropriate flag) in the storage unit 25 (step S77). In the present embodiment, biometric authentication using a fingerprint is executed in the mobile phone 1, but fingerprint information collected in advance is stored in the authentication authority server 3 or the central server 2, and the authentication authority server 3 Alternatively, the central server 2 may make the determination. Thereby, the biometric authentication using the fingerprint is completed.

  Subsequently, the process proceeds to authentication using an electronic certificate. The MPU 51 of the security chip 5 calculates a message digest using the hash function stored in the ROM 55 for the order information input in step S55 (step S76). The MPU 51 reads from the personal key file 554 the personal key of the mobile phone 1 that has been issued in advance from the certification authority server 3, and encrypts the order information and the message digest (step S81). Further, the MPU 51 reads out an electronic certificate issued in advance in the certification authority server 3 from the electronic certificate file 553, attaches the electronic certificate to the encrypted order information and message digest, and transmits it to the central server 2 (step). S82). The CPU 21 of the central server 2 stores the transmitted electronic certificate, encrypted order information, and message digest in the RAM 22.

  The CPU 21 of the central server 2 accesses the certificate authority server 3 described in the electronic certificate and requests acquisition of the public key (certificate authority public key) of the received electronic certificate (step S83). The certification authority server 3 transmits the public key of the electronic certificate to the central server 2 (step S84). The CPU 21 of the central server 2 reads out the stored electronic certificate from the RAM 22, decrypts the electronic certificate using the public key of the certification authority transmitted from the certification authority server 3, and obtains the public key of the mobile phone 1 ( Step S85).

  The CPU 21 of the central server 2 decrypts the order information and message digest encrypted using the acquired public key of the mobile phone 1 (step S91). Further, the CPU 21 calculates a message digest for the decrypted order information using the hash function stored in the storage unit 25 of the central server 2 (step S92). The CPU 21 of the central server 2 determines whether or not the message digest decrypted in step S91 matches the message digest calculated in step S92, that is, whether the order information has not been tampered with in the middle of transmission, and the authorized customer's mobile phone It is determined whether or not information is transmitted / received from the telephone 1 (step S93).

  If the message digests do not match (NO in step S93), the CPU 21 determines that some tampering or impersonation has occurred, and sets an inappropriate flag for electronic certificate authentication (step S95). On the other hand, if the message digests match (YES in step S93), an appropriate flag for electronic certificate authentication is set assuming that there is no impersonation and tampering (step S94). Then, the CPU 21 of the central server 2 stores an electronic certificate authentication flag (electronic certificate authentication appropriate flag or electronic certificate authentication inappropriate flag) in the storage unit 25 (step S96). Thereby, the authentication using the electronic certificate is completed.

  Next, environmental authentication will be described. The MPU 51 of the security chip 5 acquires the environment information of the mobile phone 1 (step S101). As described above, the environmental information is collected by the MPU 51 residently monitoring the OS, BIOS and installed software in the ROM 15 of the mobile phone 1, and the device name, OS name, version, and external connection terminal 19 of the mobile phone 1. This is done by collecting the device name and version of peripheral devices connected to the software, software name and version of installed software such as a browser. The collected environment information is stored in the environment information file 551 (step S102).

  The MPU 51 reads out the environmental information collected from the environmental information file 551 and transmits it to the central server 2 (step S103). The CPU 21 of the central server 2 stores the transmitted environment information in the RAM 22. The CPU 21 of the central server 2 reads out the class corresponding to the order information decrypted in step S91 with reference to the environment information DB 251 (step S104). That is, the CPU 21 refers to the price information or product information field, and reads the corresponding class from the class field based on the traded price or product in the order information. For example, when the amount of the product to be ordered exceeds 50,000 yen, class 1 is selected.

  The CPU 21 reads the environment information condition corresponding to the read class from the environment information DB 251 (step S105). That is, based on the read class, the corresponding device name / version, software name / version, and device name / version of the peripheral device are read from the environmental condition field. And CPU21 memorize | stored in RAM22 and judges whether the received environmental information satisfy | fills the conditions of the read environmental information (step S111). If the condition is not satisfied (NO in step S111) (for example, if the class is 1 and version 2.0 of software C is transmitted as environment information, the condition of version 3.0 or higher is not satisfied), environment authentication is not successful. An appropriate flag is set (step S112). On the other hand, if the condition is satisfied (YES in step S111), an environmental authentication appropriate flag is set (step S113). For example, when the class is 1 as the condition, the environmental information is “the device name of the mobile phone 1 is the latest model F004, the version is 2.0, the software is the version C of the software C, and the peripheral device is installed. If nothing is connected to ", it is determined that the environment is appropriate. The CPU 21 of the central server 2 stores an environment authentication flag (environment authentication appropriate flag or environment authentication inappropriate flag) in the storage unit 25 (step S114). This completes the environment authentication.

  The CPU 21 reads the fingerprint authentication flag, the electronic certificate flag, and the environment authentication flag stored in the storage unit 25, and whether or not all of the fingerprint authentication appropriate flag, the electronic certificate appropriate flag, and the environment authentication appropriate flag are set in the AND condition. Is determined (step S115). If all appropriate flags are set (YES in step S115), the mobile phone 1 is determined to be safe and a safety flag is set (step S121). In other words, the mobile phone 1 is determined to be appropriate only when it is determined to be appropriate in all of biometric authentication, electronic certificate authentication (PKI authentication), and environmental authentication. The CPU 21 of the central server 2 transmits safety assurance information and order information indicating safety to the Web server 4 (step S122).

  On the other hand, if any one of the biometric authentication, electronic certificate authentication (PKI authentication), and environment authentication is set, the improper flag is set (step S123). In this case, the CPU 21 transmits danger information indicating that the mobile phone 1 is dangerous to the Web server 4 (step S124), and ends the safety judgment subroutine (step S56).

  In FIG. 5, the Web server 4 determines whether or not the danger information of the mobile phone 1 has been received from the central server 2 (step S57). If the danger information has not been received (NO in step S57), the Web server 4 determines whether or not safety assurance information and order information have been received (step S58). If the safety guarantee information and the order information have not been received (NO in step S58), and if YES in step S57, the mobile phone 1 is likely to be fraudulent, and information requesting the suspension of the commercial transaction is sent to the mobile phone 1. Transmit (step S59). On the other hand, if the safety guarantee information and the order information are received (YES in step S58), it is assumed that the safety of the mobile phone 1 is guaranteed, and the order has been officially received and the order has been received. The received order confirmation information is transmitted to the mobile phone 1 (step S510). In this way, prior to business transactions, identity authentication, PKI authentication and environmental authentication are performed to ensure sufficient safety, and smooth business transactions are realized by changing the authentication level according to the value of the product being traded. It becomes possible.

FIG. 13 is a block diagram showing a hardware configuration of mobile phone 1 according to the second embodiment. The computer program to be executed by the mobile phone 1 according to the first embodiment can be preinstalled and provided in the mobile phone 1 as in the second embodiment, or can be provided by a CD-ROM, MO, memory card, etc. It is also possible to provide a portable recording medium. Furthermore, it is also possible to provide a computer program as a carrier wave via a line. That is, instead of mounting the security chip 5, a computer program having the same function as the security chip 5 may be installed in the ROM 15 of the mobile phone 1. The contents will be described below.

  A recording medium 1a (CD-) recorded with a program for causing the mobile phone 1 shown in FIG. 13 to authenticate biometric information, collect environmental information, transmit environmental information, transmit encrypted information, and determine safety. ROM, MO, memory card, DVD-ROM or the like) is installed in the ROM 15 of the mobile phone 1. As an installation method, a recording medium 1a such as a memory card that can be connected to the external connection terminal 19 is inserted and the program is installed, or the program according to the present invention is downloaded from the central server 2. Such a program is loaded into the RAM 12 of the mobile phone 1 and executed. Thereby, it functions as the mobile phone 1 as the information processing apparatus of the present invention as described above.

Embodiment 3
In the first embodiment, the biometric information is authenticated by the security chip 5, but may be executed by the central server 2 or the certification authority server 3. The third embodiment is a form in which authentication of biometric information is executed in the central server 2, and a form to which the present invention is applied when a security policy is determined in advance will be described.

  FIG. 14 is a block diagram showing a hardware configuration of the mobile phone 1 according to the third embodiment, and FIG. 15 is a block diagram showing a hardware configuration of the central server 2. As shown in FIGS. 14 and 15, since authentication of biometric information is executed by the central server 2, the fingerprint information file 252 for authentication is stored not in the mobile phone 1 but in the storage unit 25 of the central server 2. For authentication fingerprint information, ask the customer to visit the store, service center, etc. before authentication, confirm the identity with a license, passport, etc., and then read the fingerprint on the spot. You can make initial registration.

  16 to 20 are flowcharts showing the procedure of the safety judgment process according to the third embodiment. First, the MPU 51 of the security chip 5 transmits a signal indicating the start of safety confirmation to the central server 2 in order to perform subsequent communication (step S161). When the CPU 21 of the central server 2 receives the confirmation start signal, it determines a communication safety class (step S162). This class is determined according to a predetermined security policy. For example, if high security is required, such as issuance of resident's card, stock trading, etc. after that, it will be determined as Class 1, and if the safety of ringtones, standby screen image data, etc. is not so required , Class 6. In addition, in the payment of utility bills, etc., it is determined as Class 3 in order to ensure moderate safety.

  After determining the class, the CPU 21 of the central server 2 transmits a response signal to the confirmation start signal to the mobile phone 1 (step S163). When the response signal is received, the MPU 51 of the security chip 5 executes the control program 55P and displays a fingerprint information acquisition request on the display unit 14 (step S164). The contents to be displayed are stored in the ROM 55 in advance. For example, information such as “Put your thumb on the fingerprint acquisition unit” may be read and output to the display unit 14. When fingerprint information is input from the fingerprint acquisition unit 112, the MPU 51 of the security chip 5 receives the fingerprint information and temporarily stores it in the RAM 52 (step S165).

  Then, the MPU 51 of the security chip 5 acquires the environment information of the mobile phone 1 (step S166). As described above, the environmental information is collected by the MPU 51 residently monitoring the OS, BIOS and installed software in the ROM 15 of the mobile phone 1, and the device name, OS name, version, and external connection terminal 19 of the mobile phone 1. This is done by collecting the device name and version of peripheral devices connected to the software, software name and version of installed software such as a browser. The collected environment information is stored in the environment information file 551 (step S167).

  The MPU 51 of the security chip 5 reads out the biological information stored in the RAM 52 and the environmental information stored in the environmental information file 551 (step S168). The MPU 51 of the security chip 5 calculates a message digest using the hash function stored in the ROM 55 for the read biometric information and environment information (step S169). The MPU 51 reads from the personal key file 554 the personal key of the mobile phone 1 that has been issued in advance from the certification authority server 3, and encrypts the biometric information, the environment information, and the message digest (step S171). Further, the MPU 51 reads the electronic certificate issued in advance in the certification authority server 3 from the electronic certificate file 553, and transmits the encrypted biometric information, environment information, and message digest to the central server 2 with the electronic certificate attached thereto. (Step S172). The CPU 21 of the central server 2 stores the transmitted electronic certificate, encrypted biometric information, environment information, and message digest in the RAM 22. In this embodiment, both the biological information and the environment information are encrypted and transmitted. However, only either the biological information or the environment information may be encrypted and transmitted.

  The CPU 21 of the central server 2 accesses the certificate authority server 3 described in the electronic certificate, and requests acquisition of the public key (certificate authority public key) of the received electronic certificate (step S173). The certification authority server 3 transmits the public key of the electronic certificate to the central server 2, and the central server 2 receives the public key of the transmitted electronic certificate (step S174). The CPU 21 of the central server 2 reads the stored electronic certificate from the RAM 22, decrypts the electronic certificate using the public key of the certification authority transmitted from the certification authority server 3, and obtains the public key of the mobile phone 1 (step) S175).

  The CPU 21 of the central server 2 decrypts the biometric information, the environment information, and the message digest encrypted using the acquired public key of the mobile phone 1 (step S181). Further, the CPU 21 calculates a message digest using the hash function stored in the storage unit 25 of the central server 2 for the decrypted biometric information and environment information (step S182). The CPU 21 of the central server 2 determines whether or not the message digest decrypted in step S181 matches the message digest calculated in step S182, that is, whether the biometric information and the environment information are not falsified during transmission, or is authorized. It is determined whether or not information is transmitted / received from the customer's mobile phone 1 (step S183).

  If the message digests do not match (NO in step S183), the CPU 21 determines that there has been any falsification or impersonation, and sets an inappropriate flag for electronic certificate authentication (step S185). On the other hand, if the message digests match (YES in step S183), an appropriate flag for electronic certificate authentication is set assuming that there is no impersonation and tampering (step S184). Then, the CPU 21 of the central server 2 stores the electronic certificate authentication flag (electronic certificate authentication appropriate flag or electronic certificate authentication inappropriate flag) in the storage unit 25 (step S186).

  Subsequently, the CPU 21 of the central server 2 reads authentication fingerprint information registered in advance from the fingerprint information file 252 (step S187). The CPU 21 compares the decrypted fingerprint information with the read fingerprint information for authentication, and determines whether or not they match, that is, whether or not the fingerprint information authentication is appropriate (step S191).

  If the fingerprints match and it is determined that fingerprint information authentication is appropriate (YES in step S191), a fingerprint authentication appropriate flag is set (step S192). On the other hand, if the fingerprints do not match and it is determined that fingerprint information authentication is inappropriate (NO in step S191), a fingerprint authentication inappropriate flag is set (step S193). The CPU 21 of the central server 2 stores the fingerprint authentication flag (fingerprint authentication appropriate flag or fingerprint authentication inappropriate flag) in the storage unit 25 (step S194).

  The CPU 21 of the central server 2 reads the environment information conditions corresponding to the class determined in step S162 from the environment information DB 251 (step S195). Then, the CPU 21 determines whether or not the decrypted environment information satisfies the condition of the environment information read in step S195 (step S196). If the condition is not satisfied (NO in step S196), the environment authentication inappropriate flag is set (step S198). On the other hand, if the condition is satisfied (YES in step S196), an environmental authentication appropriate flag is set (step S197). The CPU 21 of the central server 2 stores an environment authentication flag (environment authentication appropriate flag or environment authentication inappropriate flag) in the storage unit 25 (step S201).

  The CPU 21 reads the fingerprint authentication flag, the electronic certificate flag, and the environment authentication flag stored in the storage unit 25, and whether or not all of the fingerprint authentication appropriate flag, the electronic certificate appropriate flag, and the environment authentication appropriate flag are set in the AND condition. Is determined (step S202). If all appropriate flags are set (YES in step S202), the mobile phone 1 is determined to be safe and a safety flag is set (step S203). In other words, the mobile phone 1 is determined to be appropriate only when it is determined to be appropriate in all of biometric authentication, electronic certificate authentication (PKI authentication), and environmental authentication. The CPU 21 of the central server 2 transmits a signal indicating that communication is continued to the mobile phone 1 or the Web server 4 (step S204).

  On the other hand, if at least one of the biometric authentication, electronic certificate authentication (PKI authentication), and environment authentication is set, the improper flag is set (step S205). In this case, the CPU 21 transmits a signal indicating the end of communication to the mobile phone 1 or the Web server 4 (step S206).

Embodiment 4
The fourth embodiment relates to a safety judgment system applied when patch software and firmware are provided. In a PDA, a mobile phone, a refrigerator, an air conditioner, a printer, and the like, a bug in the built-in software may be found. In this case, it is necessary to provide patch software. In some cases, firmware having an additional function is provided. In the fourth embodiment, a safety judgment system capable of providing such software to a customer while ensuring safety will be described.

  FIG. 21 is a block diagram showing a hardware configuration of mobile phone 1 according to the fourth embodiment. Reference numeral 114 shown in FIG. 21 denotes a main power supply unit (hereinafter referred to as a main power supply unit) that supplies power to the mobile phone engine unit 110, and uses a lithium battery or the like. Electric power is supplied from the main power supply unit 114 to the mobile phone engine unit 110 and the security chip 5 by operating an on button (not shown) of the input unit 13, and the mobile phone engine unit 110 is operated from the main power supply unit 114 by operating an off button (not shown). In addition, the power to the security chip 5 is cut off and the mobile phone 1 is turned off.

  On the other hand, the sub power supply means (hereinafter referred to as sub power supply unit) 115 uses, for example, a coin-type lithium battery, and the main power unit 114 does not supply power to the mobile phone engine unit 110 and the security chip 5. Even in this case, power is supplied to the second ROM 116 serving as a storage unit and the sub antenna unit 117 serving as a reception communication unit. When power is supplied from the main power supply unit 114, that is, when the mobile phone 1 is powered on, when software is transmitted from the central server 2, the software receives the software from the antenna unit 16, and the CPU 11 Stores the software in the ROM 15. In this case, power supply by the sub power supply unit 115 is not performed.

  Conversely, when power is not supplied from the main power supply unit 114, that is, when the mobile phone 1 is powered off, the sub power supply unit 115 supplies power to the sub antenna unit 117 and the second ROM 116. When software is transmitted from the central server 2, the secondary antenna unit 117 receives the software, stores the received software in the second ROM 116, and stores the software stored in the second ROM 116 when power from the main power supply is supplied. Is written into the ROM 15. The sub-antenna unit 117 may be a known FM text multiplex broadcast receiving module, for example. In this case, the central server transmits an FM character broadcast including software via the FM broadcast station. When the FM character multiplex broadcast receiving module which is the sub-antenna unit 117 receives the FM character broadcast, the software data described in the DARC standard character code is converted into the source code described in C language, Java or the like. . Finally, the MPU 51 of the security chip 5 performs personal authentication, PKI authentication, and environment authentication, and then installs software in the ROM 15.

  FIG. 22 is a block diagram showing a hardware configuration of the central server 2. As shown in FIG. 22, the storage unit 25 stores various software such as patch software, firmware, plug-in software, and vaccine that have been authenticated by the certification authority server 3. These software are provided by software companies. The electronic certificate file 253 stores the electronic certificate of the central server 2 that has been issued in advance from the certification authority server 3, and the personal key file 254 similarly has the central certificate that has been issued in advance from the certification authority server 3. The personal key of the server 2 is stored.

  Software providing processing in which safety is guaranteed in the above hardware configuration will be described using a flowchart. 23 to 29 are flowcharts showing the procedure of the software providing process according to the fourth embodiment. First, the CPU 21 of the central server 2 makes a call to the mobile phone 1 and makes an acquisition request for information on whether the main power is on or off (step S231). The mobile phone 1 transmits information on whether the main power is on or off (step S232). The central server 2 determines whether or not the main power source is on (step S233). If the main power source is on (YES in step S233), the safety class is determined as described in step S162 (step S233). S234). This security may be determined by the administrator according to the importance of the software provided. For example, in the case of patch software or vaccine software, class 1 is determined to increase safety, and software with low safety such as game software is determined as class 6.

  The CPU 21 of the central server 2 transmits an authentication start signal to the mobile phone 1 (step S235). The MPU 51 of the security chip 5 that has received the authentication start signal executes the control program 55P and displays a fingerprint information acquisition request on the display unit 14 (step S236). When fingerprint information is input from the fingerprint acquisition unit 112, the MPU 51 of the security chip 5 receives the fingerprint information (step S237) and temporarily stores it in the RAM 52. Then, the MPU 51 reads the fingerprint information stored in advance in the fingerprint information file 552 of the ROM 55 at the time of purchase of the mobile phone 1 and compares it with the fingerprint information stored in the RAM 52, that is, the fingerprint information authentication is appropriate. It is determined whether or not there is (step S241).

  If the fingerprints match and it is determined that fingerprint information authentication is appropriate (YES in step S241), a fingerprint authentication appropriate flag is set (step S243). On the other hand, if the fingerprints do not match and it is determined that fingerprint information authentication is inappropriate (NO in step S241), a fingerprint authentication inappropriate flag is set (step S242). The MPU 51 stores the transmitted fingerprint authentication flag (fingerprint authentication appropriate flag or fingerprint authentication inappropriate flag) in the storage unit 55 (step S244).

  Next, the MPU 51 of the security chip 5 acquires the environment information of the mobile phone 1 (step S245). The collected environment information is stored in the environment information file 551 (step S246). The MPU 51 reads out the environment information collected from the environment information file 551 and transmits it to the central server 2 (step S247). The CPU 21 of the central server 2 stores the transmitted environment information in the RAM 22. The CPU 21 of the central server 2 reads out the environment information condition corresponding to the class determined in step S162 from the environment information DB 251 (step S248).

  Then, the CPU 21 determines whether or not the received environment information satisfies the conditions of the read environment information stored in the RAM 22 (step S251). If the condition is not satisfied (NO in step S251), an environment authentication inappropriate flag is set (step S253). On the other hand, if the condition is satisfied (YES in step S251), an environmental authentication appropriate flag is set (step S252). The CPU 21 of the central server 2 stores an environment authentication flag (environment authentication appropriate flag or environment authentication inappropriate flag) in the storage unit 25 (step S254) and transmits it to the mobile phone 1 (step S255). The MPU 51 of the security chip 5 that has received the environment authentication flag stores the environment authentication flag (environment authentication appropriate flag or environment authentication inappropriate flag) in the storage unit 55 (step S256).

  Further, the CPU 21 of the central server 2 reads the software for provision stored in the storage unit 25 from the storage unit 25 (step S257). The CPU 21 calculates a message digest for the read software using the hash function stored in the storage unit 25 (step S258). The CPU 21 reads the personal key of the central server 2 previously issued from the certification authority server 3 from the personal key file 254, and encrypts the software and the message digest (step S259). The CPU 21 reads the electronic certificate issued in advance in the certification authority server 3 from the electronic certificate file 253, attaches the electronic certificate to the encrypted software and message digest, and transmits them to the mobile phone 1 (step S261). The MPU 51 of the security chip 5 stores the transmitted electronic certificate, encrypted software, and message digest in the RAM 52.

  The MPU 51 of the security chip 5 accesses the certification authority server 3 described in the electronic certificate, and requests acquisition of the public key of the received electronic certificate (the public key of the certification authority) (step S262). The certification authority server 3 transmits the public key of the electronic certificate to the mobile phone 1, and the MPU 51 of the security chip 5 receives the transmitted public key (step S263). The MPU 51 reads the stored electronic certificate from the RAM 52, decrypts the electronic certificate using the public key of the certification authority transmitted from the certification authority server 3, and acquires the public key of the central server 2 (step S264).

  The MPU 51 of the security chip 5 decrypts the encrypted software and message digest using the acquired public key of the central server 2 (step S265). Further, the MPU 51 calculates a message digest in the decrypted software using the hash function stored in the ROM 55 of the security chip 5 (step S266). The MPU 51 confirms whether or not the message digest decrypted in step S265 matches the message digest calculated in step S266, that is, whether the software has been tampered with in the middle of transmission, and information is transmitted / received from the authorized central server 2 It is determined whether or not it has been (step S271).

  If the message digests do not match (NO in step S271), the MPU 51 determines that there has been any falsification or impersonation, and sets an inappropriate flag for electronic certificate authentication (step S272). On the other hand, if the message digests match (YES in step S271), an appropriate flag for digital certificate authentication is set assuming that there is no impersonation and tampering (step S273). Then, the MPU 51 of the security chip 5 stores the electronic certificate authentication flag (electronic certificate authentication appropriate flag or electronic certificate authentication inappropriate flag) in the ROM 55 (step S274).

  The MPU 51 reads the fingerprint authentication flag, the electronic certificate flag, and the environment authentication flag stored in the ROM 55, and determines whether all of the fingerprint authentication appropriate flag, the electronic certificate appropriate flag, and the environment authentication appropriate flag are set under the AND condition. (Step S275). If all the appropriate flags are set (YES in step S275), it is determined that the transmitted software is safe and the safety flag is set (step S278). The MPU 51 of the security chip 5 installs the software decrypted in step S265 in the ROM 15 of the mobile phone engine unit 110 (step S2710). Then, the MPU 51 transmits a signal indicating that the installation is completed to the central server 2 (step S2711).

  On the other hand, if any one of the biometric authentication, electronic certificate authentication (PKI authentication), and environment authentication is set (NO in step S275), the inappropriate flag is set (step S279). . In this case, the MPU 51 transmits a signal indicating that installation is refused to the central server 2 (step S2712).

  If NO in step S233, that is, if the main power supply of the mobile phone 1 is off, the CPU 21 of the central server 2 reads the software for provision stored in the storage unit 25 from the storage unit 25 (step S281). The CPU 21 calculates a message digest using the hash function stored in the storage unit 25 in the read software (step S282). The CPU 21 reads the personal key of the central server 2 previously issued from the certificate authority server 3 from the personal key file 254, and encrypts the software and the message digest (step S283). The CPU 21 reads an electronic certificate issued in advance in the certification authority server 3 from the electronic certificate file 253, attaches the electronic certificate to the encrypted software and message digest, and FM broadcast station computer (not shown). (Step S284).

  The FM broadcast station computer converts the digital certificate, encrypted software, and message digest into DARC standard broadcast data, and multiplexes it into FM music data and broadcast data by an FM text broadcast multiplex circuit (not shown). . These data are FM-modulated by an FM modulation oscillator and broadcast. The cellular phone 1 receives the FM text broadcast from the sub-antenna unit 117 (step S285), converts the data described in the DARC standard character code, and extracts the electronic certificate, the encrypted software, and the message digest. A technique related to FM text broadcasting using the DARC standard is disclosed in Japanese Patent Laid-Open No. 10-116237.

  The converted electronic certificate, software, and message digest are stored in the second ROM 116 (step S286). When supply of power by the main power supply unit 114 is started by the operation of the customer input unit 13 (step S291), fingerprint authentication is performed in the same manner as the processing described in steps S236 to S244 (step S292). Environment authentication is performed in the same manner as the processing described in steps S245 to S256 (step S294), and authentication using an electronic certificate is performed in the same manner as the processing described in steps S262 to S274 (step S293). When performing authentication using an electronic certificate, the CPU 51 reads the electronic certificate, encrypted software, and message digest stored in the second ROM 116, stores them in the RAM 52, and then performs authentication using the electronic certificate. . That is, the public key acquired from the certification authority server 3 is used to acquire the public key from the electronic certificate, the software encrypted with the acquired public key is decrypted, and whether or not the decrypted software is appropriate. Judging.

  The MPU 51 reads the fingerprint authentication flag, the electronic certificate flag, and the environment authentication flag stored in the ROM 55, and determines whether all of the fingerprint authentication appropriate flag, the electronic certificate appropriate flag, and the environment authentication appropriate flag are set under the AND condition. (Step S295). If all the appropriate flags are set (YES in step S295), it is determined that the transmitted software is safe and the safety flag is set (step S296). The MPU 51 of the security chip 5 installs the decrypted software in the ROM 15 of the mobile phone engine unit 110 (step S298). Then, the MPU 51 transmits a signal indicating that the installation is completed to the central server 2 (step S299).

  On the other hand, if any one of the biometric authentication, electronic certificate authentication (PKI authentication), and environment authentication is set (NO in step S295), the improper flag is set (step S297). . In this case, the MPU 51 transmits a signal indicating that installation is refused to the central server 2 (step S2910).

  The software provided from the central server 2 may be software for deleting software in the mobile phone 1 that is the target of the DDoS attack, in addition to patch software and the like. For example, when software (program) that performs a DDoS attack is set in a predetermined Web server after several days for some reason, the software that has undergone the authentication of the present invention is provided. The provided software stores date / time information, and erases all data stored after the date / time stored by installing and executing the software.

  FIG. 30 is a flowchart showing the processing contents of the installed erasing software. In step S298, erasing software is installed in the ROM 15. The customer causes the CPU 11 to execute erasure software by operating the input unit 13 (step S301). The CPU 11 reads the storage history in the ROM 15 (step S302). More specifically, data such as stored files and installed software, and information on the date and time when those data are stored are read out. The CPU 11 reads date / time information from the execution program of the erasing software (step S303). Then, referring to the read storage history, all the data stored after the read date and time are deleted (step S304). Thereby, it can prevent that the mobile telephone 1 used as the platform of the DDoS attack is utilized for an attack.

Then, the MPU 51 reads the fingerprint information stored in advance in the fingerprint information file 552 of the ROM 55 at the time of purchase of the mobile phone 1 and compares it with the fingerprint information stored in the RAM 52, that is, the fingerprint information authentication is appropriate. It is determined whether or not there is (step S343).

  If the fingerprints match and it is determined that fingerprint information authentication is appropriate (YES in step S343), a fingerprint authentication appropriate flag is set, and the set fingerprint authentication appropriate flag is transmitted to the mobile phone 1 (step S345). On the other hand, if the fingerprints do not match and it is determined that fingerprint information authentication is inappropriate (NO in step S343), the fingerprint authentication inappropriate flag is set, and the set fingerprint authentication inappropriate flag is transmitted to the mobile phone 1. (Step S344). The CPU 11 of the mobile phone 1 stores the transmitted fingerprint authentication flag (fingerprint authentication appropriate flag or fingerprint authentication inappropriate flag) in the ROM 15 (step S346). In the present embodiment, biometric authentication using fingerprints is executed in the central server 2, but fingerprint information collected in advance is stored in the certification authority server 3 or the mobile phone 1, and the certification authority server 3 Alternatively, the determination may be made by the mobile phone 1. Thereby, the biometric authentication using the fingerprint is completed.

  Subsequently, the MPU 51 of the security chip 5 acquires the environment information of the central server 2 (step S347). As described above, the environment information is collected by the MPU 51 residently monitoring the OS, BIOS and installed software of the ROM 15 of the central server 2, and the device name, OS name, version, external communication port 29 of the central server 2. This is done by collecting the device name and version of peripheral devices connected to the software, software name and version of installed software such as a browser. The collected environment information is stored in the environment information file 551 (step S348).

  The MPU 51 of the security chip 5 reads the environment information stored in the environment information file 551 stored in the RAM 52 (step S349). The MPU 51 of the security chip 5 calculates a message digest using the hash function stored in the ROM 55 as the read environment information (step S351). The MPU 51 reads from the personal key file 554 the personal key of the central server 2 that has been issued in advance from the certification authority server 3, and encrypts the environment information and the message digest (step S352). Further, the MPU 51 reads an electronic certificate issued in advance in the certification authority server 3 from the electronic certificate file 553, and transmits the electronic certificate attached to the encrypted environment information and message digest to the mobile phone 1 (step). S353). The CPU 11 of the mobile phone 1 stores the transmitted electronic certificate, encrypted environment information, and message digest in the RAM 12.

  The CPU 11 of the mobile phone 1 accesses the certificate authority server 3 described in the electronic certificate and requests acquisition of the public key (certificate authority public key) of the received electronic certificate (step S354). The certification authority server 3 transmits the public key of the electronic certificate to the mobile phone 1, and the mobile phone 1 receives the public key of the transmitted electronic certificate (step S355). The CPU 11 of the mobile phone 1 reads out the stored electronic certificate from the RAM 12, decrypts the electronic certificate using the public key of the certification authority transmitted from the certification authority server 3, and obtains the public key of the central server 2 (step) S356).

  The CPU 11 of the mobile phone 1 decrypts the environment information and the message digest encrypted using the acquired public key of the central server 2 (step S361). Further, the CPU 11 calculates a message digest using the hash function stored in the ROM 55 of the mobile phone 1 as the decrypted environment information (step S362). The CPU 11 of the mobile phone 1 determines whether or not the message digest decrypted in step S361 matches the message digest calculated in step S362, that is, whether environmental information has not been tampered with in the middle of transmission, and the authorized central server 2 It is determined whether or not information is transmitted / received from (step S363).

  If the message digests do not match (NO in step S363), the CPU 11 determines that some tampering or impersonation has occurred, and sets an inappropriate flag for electronic certificate authentication (step S365). On the other hand, if the message digests match (YES in step S363), an appropriate flag for digital certificate authentication is set assuming that there is no impersonation and tampering (step S364). Then, the CPU 11 of the mobile phone 1 stores an electronic certificate authentication flag (electronic certificate authentication appropriate flag or electronic certificate authentication inappropriate flag) in the ROM 15 (step S366).

  The CPU 11 of the mobile phone 1 reads the environment information conditions corresponding to the class determined in step S104 from the environment information DB 151 (step S371). Then, the CPU 11 determines whether or not the decrypted environment information satisfies the condition of the environment information read in step S371 (step S372). If the condition is not satisfied (NO in step S372), the environment authentication inappropriate flag is set (step S374). On the other hand, if the condition is satisfied (YES in step S372), an environmental authentication appropriate flag is set (step S373). The CPU 11 of the mobile phone 1 stores an environment authentication flag (environment authentication appropriate flag or environment authentication inappropriate flag) in the ROM 15 (step S375).

  The CPU 11 reads the fingerprint authentication flag, the electronic certificate flag, and the environment authentication flag stored in the ROM 15, and determines whether or not all of the fingerprint authentication appropriate flag, the electronic certificate appropriate flag, and the environment authentication appropriate flag are set in the AND condition. Judgment is made (step S376). If all appropriate flags are set (YES in step S376), the central server 2 is determined to be safe, a safety flag is set, and the process proceeds to step S121 (step S377).

  On the other hand, when at least one of the biometric authentication, electronic certificate authentication (PKI authentication), and environment authentication is set (NO in step S376), the improper flag is set, and the process proceeds to step S123. The process proceeds (step S378). As described above, the mobile phone 1 and the central server 2 are determined to be safe only after all of the biometric information authentication, the environment authentication, and the electronic certificate authentication are determined to be appropriate in both the mobile phone 1 and the central server 2. Since the transmission / reception of the information is permitted, it is possible to provide a more secure communication environment.

  In the present embodiment, the mobile phone 1 and the central server 2 are secured when the biometric information authentication, the environment authentication, and the electronic certificate authentication are all determined to be appropriate by both the mobile phone 1 and the central server 2. Although the technology for allowing the transmission and reception of information thereafter is described, similarly, between the mobile phone 1 and the Web server 4 of the online shop (or other information processing devices such as other mobile phones, washing machines, personal computers not shown). For both, when it is determined that both biometric authentication, environment authentication, and electronic certificate authentication are appropriate, the mobile phone 1 and the Web server 4 are determined to be safe, and subsequent transmission / reception of information is permitted.
