Description

  The present invention relates to a mobile phone having a function that requires personal authentication and an electric lock system using the mobile phone.

In recent years, mobile phones have rapidly spread, and mobile phones are increasingly used in place of fixed phones and public phones that have been shared by families. Mobile phones are no longer owned by certain people, but it is natural that they are owned by young and elderly people, and in the future it is fully expected that they will own each kitchen. In addition, the number of functions of mobile phones is remarkable, and mobile phones are now used as communication devices for e-mail and the Internet, not just call devices, and are also being used for applications such as identification and electronic money. And if anyone has a high-performance mobile phone in this way, it is also possible to give the mobile phone a function of a key for a door of a building or a car on the condition of ensuring security. Patent Document 1 describes a mobile phone that secures security by fingerprint authentication and locks / unlocks (unlocks) a door.
However, in the mobile phone described in the document, since fingerprint collation is always performed, battery consumption is significant, and there is a restriction in layout that the fingerprint detection unit must always be in a place where the finger touches.
On the other hand, with existing mobile phones that perform fingerprint authentication and password authentication, the user selects and executes functions as necessary under the condition that the lock against unauthorized use is released in advance by fingerprint authentication or password authentication. ing. Therefore, if the user leaves or loses the mobile phone after the authentication is completed, it may be illegally used by a third party, which is not preferable.
In other words, as shown in FIG. 11, in such a mobile phone, when a fingerprint or password is entered by the user (step 1101 (described as “S1101” in the figure, the same applies hereinafter)), the registered regular phone number is entered. The user's fingerprint data or password data is collated (step 1102). In step 1103, whether the user is legitimate is confirmed by this collation. For example, an input of an operating means operated to execute highly confidential information display, telephone setting change, or door locking / unlocking as described above is accepted (step 1104). When a function is selected by the user and the operation means is actually operated, the predetermined function is executed (step 1105). Here, when there is a time interval between the authentication in step 1103 and the operation in step 1104 (that is, when the operation waiting time of the operation means becomes long), unauthorized use by a third party may occur during that time. There is a problem. Further, if the user loses the mobile phone after completing the authentication in step 1103, there is also a problem that the third party is illegally used.

Can be prevented and safety can be improved.

The best mode for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing a mobile phone according to the present embodiment and a door locked by the mobile phone, and FIG. 2 is a block diagram showing an internal configuration of the mobile phone of FIG. The mobile phone 1 includes a display unit 3, a button 4, an execution key 5, and a camera 6 on the front surface of the housing 2. The display unit 3 is composed of a liquid crystal, an organic EL, or the like. The display unit 3 displays various information such as a transmission number, an incoming call number, contents of transmitted / received mail, a standby screen, and an operation state. The button 4 functions as a numeric keypad for inputting numbers (and characters) or a function key to which various functions are assigned.
The execution key 5 is operated to execute a predetermined function requiring personal authentication. In this embodiment, the execution key 5 also serves as a fingerprint reader for acquiring the fingerprint information of the user, and the operation of the execution key 5 is used. This is done by putting a finger on the person and inputting fingerprint information.
The camera 6 can be arbitrarily used by the user for still image shooting and moving image shooting, and can be set to be activated in conjunction with the operation of the execution key 5 and used for authentication, which will be described later. (See Example 2).
The door 7 or its surroundings is provided with a receiving unit 15 for pre-registering a locking signal that should arrive from the mobile phone 1 and receiving the locking signal actually transmitted in step 307, and a locking / unlocking mechanism 16 It has been.

  As shown in FIG. 2, the housing 2 includes an antenna 8 that transmits and receives radio signals, a transmission and reception unit 9 that performs transmission processing and reception processing of transmission signals and reception signals transmitted and received by the antenna 8, Vibrator 10 for notifying the user of an alarm by vibration, microphone 11 to which uttered voice is input, speaker 12 for outputting received voice and the like, control unit 13 for integrally controlling these units, and control processing of control unit 13 And a memory 14 for storing personal information of the user and the like.

Next, a case where the mobile phone 1 locks the building door 7 will be described as a predetermined function requiring personal authentication.
FIG. 3 is a flowchart showing a locking procedure by the mobile phone according to the present embodiment.
When the door 7 is locked by the mobile phone 1, as shown in FIG. 3, the user operates the button 4 and selects “lock door” from the menu displayed on the display unit 3 ( In step 301, the fingerprint of the finger is applied to the execution key 5 to confirm this selection (step 302). In the mobile phone 1, fingerprint information of the finger of a regular user who is the owner or the like is registered in the memory 14 in advance, and when the control unit 13 acquires the fingerprint information of the user in step 302, it is stored in the memory. 14 is collated with that of an authorized user stored in 14 (step 303).
After collation in step 303, in step 304, it is confirmed whether or not the input fingerprint information matches the fingerprint information registered in the memory 14. If it is determined that they do not match, the control unit 13 displays an error message on the display unit 3. It is displayed (step 305). On the other hand, if it is determined in step 304 that the fingerprint information matches, the control unit 13 generates a locking signal for locking the door 7 (step 306), and sends this to the door 7 via the transmission / reception unit 9 and the antenna 8. Then, the data is transmitted (step 307).
When receiving the locking signal, the receiving unit 15 confirms whether or not it matches the registered locking signal (step 308), and as long as it matches the registered locking signal, the locking / unlocking mechanism 16 of the door 7 is reached. When the door 7 is unlocked, it is locked (step 309). The collation of the fingerprint information in steps 303 and 304 and the generation of the lock signal in step 306 may be performed by generating a password by, for example, encrypting the fingerprint information. The same may be done.

  In the mobile phone according to the present embodiment, the execution key 5 for executing a predetermined function requiring personal authentication is not operated as necessary in a state where the lock for unauthorized use is released by performing authentication in advance. Since the user's biometric information (fingerprint information) is acquired and authentication is performed at the stage where the execution key 5 is actually operated, the operation timing of the execution key 5 and the authentication timing are close in time, It is possible to effectively prevent unauthorized use by a third party without always performing personal authentication. In this embodiment, in particular, the execution key 5 is commonly responsible for acquiring fingerprint information, so that not only can the number of parts be reduced and the arrangement space thereof can be reduced, but the operation timing and authentication timing can be reduced. It coincides and becomes almost simultaneous, and unauthorized use is surely prevented.

In the first embodiment, only the user's fingerprint information is used for personal authentication, but in this embodiment, a case where the user's face information is also used will be described.
FIG. 4 is a flowchart showing a locking procedure by the mobile phone according to the present embodiment.
As shown in FIG. 4, when the control unit 13 obtains the fingerprint information of the user in step 302, the control unit 13 activates the camera 6 to capture the user's face image (step 401). In this embodiment, the regular user's face image information is also registered in the memory 14 in advance, and the control unit 13 determines whether or not the acquired fingerprint information is authentic by comparing it with the registered information. At the same time (steps 303 and 304), whether or not the acquired face image information is legitimate is also determined by comparing with the registered information (steps 402 and 403). Note that the order of step 401 and steps 303 and 304 may be reversed, and the image may be taken only when fingerprint authentication is obtained in step 304.
In step 403, when the control unit 13 determines that the input face image information and the face image information registered in the memory 14 do not match, an error message is displayed on the display unit 3 (step 404). On the other hand, if the control unit 13 determines that the pieces of face image information match, the processing after step 306 is performed as in the first embodiment.
In the mobile phone according to the present embodiment, not only fingerprint information but also face information is used for user authentication, so that the accuracy of authentication becomes stricter and unauthorized use by a third party can be prevented more reliably.

In the first embodiment, the control unit 13 displays an error message on the display unit 3 when determining that the acquired fingerprint information does not match the pre-registered fingerprint information. In the present embodiment, the control unit 13 displays an error message. Instead, (or an error message is displayed), a case where the fact is notified to the notification destination registered in advance in the memory 14 will be described.
FIG. 5 is a flowchart showing a locking procedure by the mobile phone according to the present embodiment.
As shown in FIG. 5, when it is determined in step 304 that the input fingerprint information does not match the registered information, the control unit 13 does not use step 305 (or after step 305). Using the communication network, a report is made by telephone, fax, or e-mail to the previously registered report destination (step 501). The content of the notification in step 501 may simply indicate that there has been unauthorized use (unauthorized use). However, if there is a past history of unauthorized use in the memory 14 as described in the fourth embodiment, the past information A report corresponding to the history (for example, a report that there has been an unauthorized use by the same person as an unauthorized user for ** year * month * day * hour **) may be made.
In the mobile phone according to the present embodiment, the possibility of unauthorized use by a third party can be communicated to related places at an early stage, and the security can be further improved.

  In this embodiment, as shown in the flowchart of the locking procedure using the mobile phone shown in FIG. 6, the control unit 13 determines whether or not the acquired fingerprint information matches the pre-registered fingerprint information, and then determines the determination target. (Acquired fingerprint information) and determination results (regular use or unauthorized use) are stored in the memory 14 as a verification history, and the history is also stored for the update (steps 601 and 602). Thereby, management of locking / unlocking of the door 7 and identification of an unauthorized user can be provided.

In each of the above embodiments, collation of input fingerprint information and the like was performed by the mobile phone 1, but in this embodiment, as in the explanatory diagram showing the electric lock system according to the present embodiment shown in FIG. The collation is performed by the collation device 17 provided in or around the door 7, and the mobile phone 1, the door 7 and the collation device 17 constitute an electric lock system 18.
The verification device 17 includes an antenna 19 that transmits and receives radio signals, a transmission and reception unit 20 that performs transmission processing and reception processing of transmission signals and reception signals transmitted and received by the antenna 19, a control unit 21, a memory 22, an LED, and the like. An error lamp 23 is provided. In the memory 22, fingerprint information of a legitimate user's finger is previously converted into a password and registered.

Here, the locking procedure by the electric lock system of a present Example is demonstrated using the flowchart of FIG.
As shown in FIG. 8, when fingerprint information is input in step 302, the control unit 13 converts it into a personal identification number and then transmits it to the verification device 17 via the transmission / reception unit 9 and the antenna 8 (step 801). ). When the transmission / reception unit 20 of the verification device 17 receives the password from the mobile phone 1 via the antenna 19 (step 802), the control unit 21 obtains the received password and the password registered in the memory 22. Collation is performed (step 803), and it is confirmed whether or not the passwords match (step 804). If the control unit 21 determines in step 804 that the passwords do not match, the controller 21 turns on the error lamp 23 to notify the user (step 805). If the password is determined to match, the controller 21 locks / unlocks. If the door 7 is unlocked via the mechanism 16, it is locked (step 806).

In the electric lock system according to the present embodiment, since the fingerprint information is collated by the collation device 17 provided on the door 7 side, the processing load on the mobile phone 1 can be reduced, and the power consumption can be reduced. It is possible to reduce the cost and size of the control unit 14 due to a decrease in the number of devices constituting the control unit 14 and the need for high performance, and further downsizing of the mobile phone terminal itself. In addition, since the fingerprint information of a legitimate user as a reference for verification is registered on the side of the door 7, there is a possibility of personal information leaking due to loss of the mobile phone 1, etc., and forgery of the lock signal and unlock signal The possibility of this can be reduced.
In addition, a comparison with a case where a fingerprint reader is installed on the side of the door 7 and authentication is performed. In such a case, the fingerprint reader is easily soiled and inferior in terms of hygiene and fingerprint recognition rate. Therefore, it is difficult to install the fingerprint reader at an appropriate position in a situation where people of various physiques (heights) use in common. In addition, it is costly to install the fingerprint reader for each door, and when installing a fingerprint reader for primary authentication, especially for condominium auto-locks, the user's fingerprint pattern itself is provided to a third party. However, according to the electric lock system, these problems do not occur.

Note that the present invention is not limited to the above-described embodiment. For example, in the second to fourth embodiments, modifications to the first embodiment are shown. However, these modifications may be applied to the fifth embodiment. Moreover, you may combine suitably.
Here, using the flowchart showing another example of the locking procedure by the electric lock system of FIG. 7 shown in FIG. 9 and FIG. 10, illustrating the case where the configuration for issuing the notification at the time of unauthorized use is applied to Example 5, In FIG. 9, instead of turning on the error lamp 23 (or turning on the error lamp 23), the control unit 21 directly reports to a predetermined report destination using a public telephone network or a dedicated line (step 901). On the other hand, in FIG. 10, the control unit 21 reports to the mobile phone 1 as a predetermined report destination (step 1001), and uses the transmission function of the mobile phone 1 (using the form telephone network or the packet communication network). ) Furthermore, another reporting destination is notified (step 1002).
In each of the above embodiments, the execution key 5 is commonly used as the operation means and the biometric information acquisition means. However, each means may be provided in a different form, and the personal information can be provided by face information or other biometric information regardless of the fingerprint information. You can authenticate.
Further, in the present embodiment, the description has been made using the personal identification number. However, the present invention is not limited to the identification using the personal identification number, and other authentication data in addition to the personal identification number such as authentication using the fingerprint shape for solid recognition. An authentication method may be used.
