[Prior art]
2. Description of the Related Art Conventionally, a personal authentication system using a card (recording medium) such as a magnetic card, a contact type IC card, and a non-contact type IC card has been used for room entry / exit management and device use management. In such a personal authentication system, a card holder makes a card reader read ID information magnetically or electronically recorded on the card, and the ID information read by the card reader is registered in advance as ID information. If it matches, the owner of the card is authenticated as a legitimate person.
[0005]
For example, such a personal authentication system can be used for a security system that controls unlocking of a locked door. In this security system, the locked door is unlocked only when the card holder is authenticated as an authorized person in the personal authentication system. Therefore, a person who does not have an authorized card cannot unlock the locked door. Thereby, human security of the space inside the door can be maintained.
[0006]
However, in the personal authentication system as described above, if the ID information read from the card matches the pre-registered ID information, the owner of the card is always authenticated as a legitimate person. Even the person who obtained it is authenticated as a legitimate person. In order to solve such a drawback, a ten-key unit is provided in the vicinity of the card reader, and both the ID information read from the card by the card reader and the password input by operating the ten-key unit are checked. A system for performing personal authentication has been proposed (for example, see Patent Document 1). In such a system, a person who illegally obtains the card cannot be authenticated as a legitimate person without knowing the password.
[0007]

[0008]
[Problems to be solved by the invention]
However, in such a personal authentication system, a legitimate cardholder must always perform an operation of inputting a personal identification number in addition to an operation of reading a card, and this operation is complicated. Therefore, when such a personal authentication system is applied to a security system that controls the unlocking of a locked door as described above, it takes time to operate the door, and the door of a room where many people frequently enter and leave repeatedly. In such a case, smooth entry and exit of a person may be hindered.
[0009]
Therefore, the present invention has been made to solve the above-described problem, and it is possible to perform personal authentication with a simple operation and to prevent a person who has illegally obtained a card from being authenticated as an authorized person. Personal authentication system and method are provided.
[0010]
The present invention also provides a security system to which such a personal authentication system is applied.
[0011]
Further, the present invention provides an ID information reading system applicable to such a personal authentication system.
[0012]
[Means for Solving the Problems]
The personal authentication system according to the present invention includes: a plurality of reading devices; an ID information acquisition unit configured to acquire the ID information read from any of the plurality of reading devices from a recording medium on which ID information is recorded; A correspondence storage unit for storing a registration correspondence relationship that is a correspondence relationship between the determined registration ID information and the reading device; and an ID information acquired by the ID information acquisition device and a reading device that reads the ID information. Determining means for determining whether the correspondence corresponds to the registered correspondence stored in the correspondence storage means, and performing personal authentication based on a result of the determination by the determining means. You.
[0013]
With such a configuration, the person holding the recording medium on which the registered ID information (registered ID information) is recorded is determined by the correspondence (registration correspondence) between the predetermined registration ID information and the reading device. When a reading operation of the recording medium is performed on a reading device corresponding to ID information (registered ID information) recorded on the recording medium, ID information read from the recording medium by the reading device is obtained. It is determined that the correspondence between the acquired ID information and the reading device matches the registration correspondence. Based on this determination result, the owner of the recording medium can be authenticated as a legitimate person.
[0014]
On the other hand, the person holding the recording medium on which the registered ID information (registered ID information) is recorded is recorded on the recording medium determined by the correspondence (registered correspondence) between the predetermined registration ID information and the reader. When a reading operation of the recording medium is performed on a reading device other than the reading device corresponding to the input ID information (registered ID information), the correspondence relationship between the ID information acquired from the reading device and the reading device becomes: It is determined that the registered correspondence does not match. Based on the result of the determination, it is possible to prevent the authentication that the owner of the recording medium is a legitimate person.
[0015]
Therefore, a person who knows the reader corresponding to the ID information recorded on the recording medium determined by the correspondence (registration correspondence) between the predetermined registration ID information and the reader is required to record on the reader. By performing a read operation of the medium, the user can be authenticated as an authorized person. On the other hand, a person who has illegally obtained the recording medium does not know the reader corresponding to the ID information recorded on the recording medium determined by the registration correspondence, so that the recording medium is surely transmitted to such a reader. Cannot perform read operation. Therefore, if a person who illegally obtains the recording medium performs a reading operation of the recording medium on a reading device other than the above-described reading device, the person cannot be authenticated as an authorized person.
[0016]
The ID information to be recorded on the recording medium is not particularly limited as long as the information is given to a person who is to be authenticated as a legitimate person. Or the same information (single registration ID information) for all individuals.
[0017]
The recording medium on which the ID information is recorded is not particularly limited as long as there is a reader for reading the ID information regardless of contact or non-contact. Magnetic cards, contact IC cards, non-contact IC cards It may be a card-shaped recording medium such as an optical card or the like, from which ID information can be read by a card reader, or may have another shape.

[0019]
With such a configuration, it is determined whether or not the correspondence between the acquired ID information and the reading device that has read the ID information matches the registration correspondence that is a predetermined correspondence between the registration ID information and the reading device. Can be determined. For a recording medium on which ID information different from the registered ID information is recorded or a recording medium in which ID information cannot be read normally, the correspondence between the ID information read by the reader and the reader is determined. As soon as it is determined that the ID information acquired from the reader does not match the registered ID information, it is possible to refrain from giving authentication to a person who possesses such a recording medium.
[0020]
Further, in the personal authentication system according to the present invention, each of the plurality of readers is a non-contact IC card reader, the storage medium is a non-contact IC card, and the ID information acquisition means includes an ID information acquisition unit. It can be configured to acquire the ID information read by any of the plurality of non-contact IC card readers from the recorded non-contact IC card.
[0021]
With such a configuration, the reading operation of the recording medium with respect to the reading device is performed in a non-contact manner, so that it is difficult to specify the position of the reading device where the reading operation of the recording medium is actually performed, and the reading operation of the recording medium is difficult.

[0037]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0038]
The security system according to the first embodiment of the present invention is configured as shown in FIG.
[0039]
In FIG. 1, this security system includes an authentication system 10 and an electric lock 30 provided on a door of a room for ensuring security. The authentication system 10 includes a plurality (five) of non-contact type IC card readers 11, 12, 13, 14, 15 (reading devices), a control unit 16, a data storage unit 17, and an operation unit 18. Each of the non-contact type IC card readers 11 to 15 performs wireless communication with the non-contact type IC card 20 (recording medium) existing in the predetermined range, and records the ID number (ID) recorded on the non-contact type IC card 20. Information). The control unit 16 performs an authentication process based on the ID number read by any one of the plurality of non-contact type IC card readers 11 to 15. The data storage unit 17 stores information necessary for the authentication process performed by the control unit 16. The operation unit 18 is operated by an operator, and supplies information based on the operation by the operator to the control unit 16. The control unit 16 of the personal authentication system 10 controls the unlocking of the locked electric lock 30 based on the result obtained by the authentication processing.
[0040]
The plurality of non-contact type IC card readers 11 to 15 are installed, for example, on a wall near a door provided with an electric lock 30, as shown in FIG.
[0041]
In FIG. 2, a circular reading area mark 40 is drawn on the surface of the wall near the door where the electric lock 30 is provided. Five non-contact type IC card readers 11, 12, 13, 14, 15 are embedded in the wall on which the reading area mark 40 is displayed. The non-contact type IC card reader 13 is arranged at the center in the reading area mark 40, the non-contact type IC card readers 11 and 15 are arranged above and below the non-contact type IC card reader 13, and further, the non-contact type IC card Readers 12 and 14 are arranged on the left and right of the non-contact type IC card reader 13. By arranging the non-contact type IC card readers 11 to 15 as described above, the ID number can be read from the non-contact type IC card 20 at different positions using the read area mark 40 as a guide.
[0042]
The data storage unit 17 stores a registration correspondence table as shown in FIG. Numbers (non-contact type IC card reader numbers) 1, 2, 3, 4, and 5 for specifying the non-contact type IC card readers 11, 12, 13, 14, 15 are given to them. The registration correspondence table represents a correspondence between each predetermined registration ID number and a contactless IC card reader number (hereinafter, referred to as registration correspondence as necessary). Each time an ID number is registered, a contactless IC card reader number corresponding to the registered ID number is determined, and their correspondence is input from the operation unit 18 as a registration correspondence. The registration correspondence input from the operation unit 18 is added to the registration correspondence table of the data storage unit 17 via the control unit 16.
[0043]
The control unit 16 performs processing according to the procedure shown in FIG.
[0044]
In FIG. 4, the control unit 16 is in a state of waiting for input of an ID number read from the non-contact type IC card 20 by one of the plurality of non-contact type IC card readers 11 to 15 (S1). A person who wants to unlock the electric lock 30 reads any one of the non-contact type IC cards 20 carried by the user and reads any one of the non-contact type IC card readers 11 to 15 arranged as shown in FIG. Hold over the implant site. The non-contact type IC card reader embedded in the portion where the non-contact type IC card 20 is held over performs wireless communication with the non-contact type IC card 20 and reads the ID number from the non-contact type IC card 20.
[0045]
The non-contact type IC card reader that has read the ID number supplies the ID number to the control unit 16. As described above, when acquiring the ID number from the non-contact type IC card reader (YES in S1), the control unit 16 in the ID number input waiting state receives the ID number from the non-contact type IC card reader (YES in S1). With reference to FIG. 3), the retrieval process of the acquired ID number is performed (S2), and it is determined whether or not the registered ID number is the same as the acquired ID number in the registration correspondence table (S3). When it is determined that the registration ID number identical to the acquired ID number is present in the registration correspondence table (YES in S3), the control unit 16 further determines the same as the acquired ID number determined by the registration correspondence relation. The non-contact type IC card reader number corresponding to the registered ID number is compared with the number assigned to the non-contact type IC card reader that has read the ID number (S4), and it is determined whether or not those numbers match. A determination is made (S5).
[0046]
If it is determined that the numbers match (YES in S5), the correspondence between the acquired ID number and the non-contact type IC card reader that has read the ID number matches the registration correspondence, so that control is performed. The unit 16 authenticates a person who has performed a reading operation on the non-contact type IC card reader of the non-contact type IC card 20 as an authorized person, and supplies an unlock control signal to the electric lock 30 (S6). The locked electric lock 30 is unlocked by the unlock control signal. On the other hand, if it is determined that the numbers do not match (NO in S5), the correspondence between the acquired ID number and the contactless IC card reader that has read the ID number is included in the registration correspondence table. The control unit 16 does not match any of the registration correspondences, and the control unit 16 issues a warning message without authenticating a person who has performed a reading operation of the non-contact type IC card 20 to the non-contact type IC card reader as an authorized person. A predetermined process related to the refusal of unlocking, such as the output of a password, is performed (NG). Thus, the electric lock 30 is not unlocked.
[0047]
Since the above-described processing is performed, the contactless IC card reader (number) corresponding to the ID number (registered ID number) recorded on the own contactless IC card 20 determined in the registration correspondence relationship That is, an authorized holder of the non-contact type IC card 20 that knows the buried portion reads the non-contact type IC card 20 and uses the area mark 40 as a guide to check the non-contact type IC card reader. The locked electric lock 30 can be unlocked by holding it over the buried part. On the other hand, the unauthorized holder of the non-contact IC card 20 cannot know the non-contact IC card reader corresponding to the ID number recorded on the non-contact IC card 20 determined in the registration correspondence, Even if the contactless IC card 20 is held over an arbitrary position in the reading area mark 40, the correspondence between the contactless IC card reader that has read the ID number and the ID number does not match the registration correspondence, The electric lock 30 cannot be unlocked.
[0048]
According to the security system as described above, the legitimate holder of the non-contact IC card 20 holds the non-contact IC card 20 over the embedded portion of the legitimate non-contact IC card reader determined by the registration correspondence. Only by a normal operation, the user is authenticated as an authorized person and the electric lock 30 can be unlocked. However, since the unauthorized holder of the non-contact type IC card 20 cannot operate the regular non-contact type IC card reader determined by the registration correspondence, the person is prevented from being authenticated as a legitimate person. The unlocking of the electric lock 30 is prevented. Therefore, the security can be improved without forcing the authorized holder of the non-contact type IC card 20 to perform an extra operation.
[0049]
In addition, even if an unauthorized person intercepts the operation of holding the non-contact type IC card 20 over the embedded portion of the normal non-contact type IC card reader using the reading area mark 40 as a guide, the operation of the regular non-contact type IC card reader is performed. It is difficult to accurately determine the location of the card reader. Therefore, the legitimate non-contact type IC card reader has a high resistance to illegal knowledge of the embedded portion.
[0050]
Further, since the reading area mark 40 is drawn, an ordinary person (including an unauthorized person) holds the non-contact type IC card 20 over the center thereof. Therefore, the non-contact type IC card reader 11, 12, 14, 15 (see FIG. 2) embedded in a portion other than the center of the reading area mark 40 (see FIG. 2) records the ID number in which the correspondence is defined. With regard to the type IC card 20, the possibility that an unauthorized person accidentally holds the non-contact type IC card 20 over the embedded portion of a regular non-contact type IC card reader is reduced.
[0051]
As described above, an ordinary person holds the non-contact type IC card 20 over the central part of the reading area mark 40. Therefore, the non-contact type IC card reader is not embedded in the central part of the reading area mark 40. You can also do so. When the non-contact type IC card reader 13 is buried in the central portion, the registration correspondence between the non-contact type IC card reader 13 (No. 3) and the registration ID number may not be created. Further, when the non-contact type card reader 13 is buried in the center of the reading area mark 40, the registration ID number corresponding to the non-contact type IC card reader 13 is stored in another non-contact type IC card reader, for example, a non-contact type IC card reader. It can also be associated with the contact type card reader 11. In this case, when the same ID number as the registered ID number is read by the non-contact type ID card reader 13 and further read by the non-contact type card reader 11, regular authentication is performed. be able to.
[0052]
Security can be further improved by the above-described device resulting from the ordinary person holding the non-contact type IC card over the central portion of the reading area mark 40.
[0053]
In the above-described processing (see FIG. 4), when it is determined that there is no registered ID number identical to the ID number acquired from the non-contact type IC card reader (NO in S3), the control unit 16 sets the non-contact type A predetermined process related to unlock rejection, such as outputting a warning message, is performed without authenticating a person who has performed a reading operation of the non-contact type IC card reader of the non-contact type IC card 20 as an authorized person (NG). With this process, a non-contact type IC card on which an ID number different from the registered ID number is recorded, or a non-contact type IC card in which the ID number cannot be read normally can be read by the non-contact type IC card reader. The predetermined process relating to the refusal to unlock is performed without determining the correspondence between the given ID number and the contactless IC card reader. Therefore, the processing is simplified.
[0054]
Next, a security system according to a second embodiment of the present invention is configured as shown in FIG. The security system according to the second embodiment differs from the security system according to the first embodiment in that authentication and unlock control of the electric lock 30 are performed in consideration of illuminance.
[0055]
In FIG. 5, this security system has an authentication system 10 and an electric lock 30, as in the first embodiment. The authentication system 10 includes a plurality of (five) non-contact type IC card readers 11, 12, 13, 14, buried in a wall as shown in FIG. 2, as in the first embodiment. 15, a control unit 16, a data storage unit 17, and an operation unit 18. The authentication system 10 further includes an illuminometer 19 for measuring illuminance (brightness) around the wall where the non-contact type IC cards 11 to 15 are embedded.
[0056]
The data storage unit 17 stores a registration correspondence table as shown in FIG. In this registration correspondence table, a plurality of types of registration correspondences corresponding to the registration ID numbers and the contactless IC card reader numbers are set according to the illuminance range. That is, an illuminance range of less than 20 lux (Lx), an illuminance range of 20 lux to less than 40 lux, an illuminance range of 40 lux to less than 60 lux, an illuminance range of 60 lux to less than 80 lux, and an illuminance range of 80 lux or more Different types of registration correspondences (correspondences between registration ID numbers and contactless IC card reader numbers) are set for each of them.
[0057]
The control unit 16 performs processing according to the procedure shown in FIG.
[0058]
In FIG. 7, the control unit 16 is in a state of waiting for input of an ID number read from the non-contact type IC card 20 by any of the plurality of non-contact type IC card readers 11 to 15 (S11). When a person who wants to unlock the electric lock 30 holds the non-contact type IC card 20 over the read area mark 40 (see FIG. 2) as a guide, the user holds the non-contact type IC card 20 over any of the embedded portions of the non-contact type IC card readers 11 to 15. A non-contact type IC card reader embedded in a portion where the non-contact type IC card 20 is held holds wireless communication with the non-contact type IC card and reads an ID number from the non-contact type IC card 20.
[0059]
As described above, upon acquiring the ID number from the non-contact type IC card reader that has read the ID number, the control unit 16 in the ID number input waiting state issues an illuminance measurement request to the illuminometer 19 (S12). , And enters a state of waiting for input of the measured illuminance (S13). The illuminometer 19 that has received the illuminance measurement request from the control unit 16 measures the illuminance and sends the measured illuminance value to the control unit 16. When inputting the measured illuminance value from the illuminometer 19 (YES in S13), the control unit 16 that is in a measurement illuminance input waiting state refers to the registration target table (see FIG. 6) stored in the data storage unit 17 A search process for the acquired ID number is performed (S14), and it is determined whether or not the registered ID number is the same as the acquired ID number in the registration correspondence table (S15).
[0060]
If it is determined that the registered ID number identical to the acquired ID number is present in the registration correspondence table (YES in S15), the control unit 16 further determines the measured illuminance value input from the illuminometer 19 and the acquired Based on the registered ID number and the same registered ID number, a non-contact type IC card reader number corresponding to the registered ID number determined by the registered correspondence of the type set for the illuminance range including the measured illuminance value Search (S16). Then, the control unit 16 compares the contactless IC card reader number obtained as a result of the search with the number assigned to the contactless IC card reader that has read the ID number (S17). It is determined whether the numbers match (S18).
[0061]
If it is determined that those numbers match (YES in S18), the correspondence between the acquired ID number and the non-contact type IC card reader that has read the ID number is determined for the illuminance range including the measured illuminance value. The control unit 16 authenticates a person who has performed a reading operation on the non-contact type IC card reader of the non-contact type IC card reader 20 as a legitimate person. An unlock control signal is supplied to 30 (S19). The locked electric lock 30 is unlocked by the unlock control signal.
[0062]
On the other hand, if it is determined that the numbers do not match (NO in S18), the correspondence between the acquired ID number and the non-contact type IC card reader that has read the ID number indicates the illuminance range including the measured illuminance value. Does not match any of the registration correspondences of the types set for, and the control unit 16 performs a predetermined process of unlock rejection such as outputting a warning message (NG). Thus, the electric lock 30 is not unlocked.
[0063]
Knowing a non-contact IC card reader (number) corresponding to an ID number (registered ID number) recorded on its own non-contact IC card 20 determined by the type of registration correspondence set in each illuminance range That is, the authorized holder of the non-contact type IC card 20 that knows the buried part determines the current brightness (illuminance) and determines the normal non-contact type IC card 20 based on the registered correspondence at that brightness. The non-contact IC card 20 can be held over an embedded portion of the non-contact IC card reader determined as the IC card reader. By the above-described processing in the authentication system 10 for such an operation, the authorized holder of the non-contact IC card 20 unlocks the locked electric lock 30 after being authenticated as an authorized person. be able to.

If so, the registration correspondences applied to each differ. Therefore, even if the non-contact type IC card 20 is held over a site that the unauthorized person has peeped at, the correspondence between the non-contact type IC card reader embedded in the site and the ID number read from the non-contact type IC card reader is read. Does not match the registration correspondence applied to the illuminance at that time, and the electric lock 30 is not unlocked.
[0066]
As described above, the security is further improved by changing the registration correspondence (correspondence between the registration ID number and the contactless IC card reader) applied at the time of authentication in accordance with the contents of the illuminance condition (illuminance range). Can be done.
[0067]
In the second embodiment, the registration correspondence applied at the time of authentication is changed according to the contents of the illuminance condition around the embedded wall of the plurality of non-contact type IC card readers 11 to 15. The registration correspondence can be changed according to the contents of other environmental conditions, for example, temperature conditions, humidity conditions, and atmospheric pressure conditions. In that case, measuring instruments (thermometer, hygrometer, barometer) necessary for determining the contents of the applied environmental conditions are used.
[0068]
Further, in addition to the above-described environmental conditions, the registration correspondence applied at the time of authentication can be changed in accordance with the temporal conditions or the contents of other conditions. When the registration correspondence applied at the time of authentication is changed according to the content of the time condition, it is necessary to change the registration correspondence for each time period (for example, every three hours, in the morning time period and in the afternoon time, the work time zone and the Different types of registration correspondences (correspondences between registration ID numbers and contactless IC card reader numbers) may be set in the registration correspondence table (at time periods other than the above). Then, the authentication system 10 may include a clock for determining the time zone instead of the illuminometer 19.
[0069]
As the other condition, a condition defined as a rule among those who use the security system (authentication system 10) can be used. In this case, there is no particular limitation as long as the contents of the condition can be recognized by the persons and the authentication system 10 can determine the condition. For example, a mark or a number to be displayed on a display provided near the plurality of non-contact type IC card readers 11 to 15, an operation state of a predetermined device provided near the plurality of non-contact type IC card readers 11 to 15 Can be used as the condition. When a mark or a number to be displayed on the display is used as the condition, different types of registration correspondence may be set in the registration correspondence table according to the shape, color, or number of the mark to be displayed. When the operating state of the predetermined device is used as the condition, different types of registration correspondence may be set in the registration correspondence table according to the high-speed operation, the medium-speed operation, the low-speed operation, and the like of the predetermined device.
[0070]
In addition, in the system in which the registration correspondence is changed according to the contents of the environmental conditions and the contents of the temporal conditions as described above, a display for displaying the contents of the current environmental conditions and the time conditions is provided. A plurality of non-contact type IC card readers 11 to 15 may be arranged in the vicinity of the installation. Thereby, the authorized holder of the non-contact type IC card 20 accurately recognizes the contents of the environmental conditions and the time conditions when performing the reading operation of the non-contact type IC card 20 with respect to the non-contact type IC card reader. Will be able to do it. Therefore, erroneous operation of the non-contact type IC card 20 by an authorized holder can be prevented.
[0071]
Further, the first and second embodiments described above are systems using a non-contact type IC card and a non-contact type IC card reader. However, the present invention is not limited to this, and a magnetic card and a magnetic card reader may be used. System that uses a contact-type IC card and a contact-type IC card reader, an optical system that reads an object and ID information (such as a bar code) described on the object. The present invention can be applied to a system using the above-described reading device, or a system using a semiconductor memory unit and a reading device to which the semiconductor memory unit can be connected.
[0072]
【The invention's effect】
As described above, according to the present invention, it is possible to know a reader corresponding to ID information recorded on a recording medium determined by a correspondence (registration correspondence) between predetermined registration ID information and a reader. Is authenticated as an authorized person by performing a reading operation on the recording medium with respect to the reading device, while notifying the reading device corresponding to the ID information recorded on the recording medium determined by the registration correspondence. An unauthorized holder of a blank card cannot reliably read a recording medium to such a reading device, and thus cannot be reliably authenticated as a legitimate person. Therefore, it is possible to provide a personal authentication system and method that can perform personal authentication with a simple operation and can prevent a person who has illegally acquired a recording medium from being authenticated as an authorized person.
