Description

  The present invention relates to an electronic device having a function of authenticating a handler in a device that requires management of the handler or a device that requires security.

  Conventionally, the security of devices such as POS (Point-Of-Sale) terminals and ECR (Electronic Cash Register) that need to be managed by the operator and terminals that can access databases such as personal information is secured. For necessary equipment, the operator is authenticated, and only authorized operators are allowed to use the equipment.

In recent years, there is a technique of reading information stored in an RFID tag using RFID (Radio Frequency Identification) technology and permitting the use of the device based on the read information (for example, see Patent Document 1). ).
JP 2003-36479 A

  However, in the case described in Patent Document 1, it is possible to save the trouble of inputting information for authentication, but since the person who has the RFID tag is not verified whether it is the real owner, Management of handlers could not be performed strictly and sufficient security could not be ensured.

  In order to strictly authenticate the handler, biometric authentication using fingerprints or irises can be considered. However, if high-precision authentication is performed, it takes time to perform authentication and an operation to read biometric information is required. It was so easy to use.

  The present invention has been made to solve the conventional problems, and provides an electronic device with a user authentication function that is easy to use and capable of strictly managing a handler and ensuring security. For the purpose.

  The electronic device of the present invention is a wireless receiving unit that receives information including personal identification information and biometric authentication information from a wireless tag, determines whether the device is permitted to be used based on the identification information, and is permitted to use the device. If not, the wireless tag control unit for disabling the device, the biometric information reading unit for reading the biometric information of the handler, the biometric information read by the biometric information reading unit and the biometric authentication information are collated It has the structure provided with the biometrics authentication control part which determines whether a handler is the owner registered into the said radio | wireless tag, and cancels business, when the said handler is not the said owner.

  With this configuration, in addition to the authentication based on the identification information stored in the wireless tag, the biological information read by the biological information reading unit is authenticated by the biological authentication information of the wireless tag. Therefore, it is possible to strictly authenticate the handler and to shorten the processing time for biometric authentication.

  Here, the biometric authentication information is configured to be feature information obtained by extracting only information on characteristic portions of the biometric information.

  With this configuration, the data amount of biometric authentication information can be reduced, and the biometric authentication processing time can be shortened.

  Further, the biometric information reading unit is a fingerprint sensor, and the fingerprint sensor is built in a key related to completion of operation of the device.

  With this configuration, the biological information can be read without performing an operation for reading the special biological information, and the operability can be improved.

  In addition, a level of authority is given to the owner of the wireless tag, and the work that can be executed according to the level can be set.

  With this configuration, a work that can be executed is automatically set according to the set authority level. Therefore, it is not necessary to switch authority for selecting a specific task, and operability can be improved.

  According to the present invention, the owner of the wireless tag is authenticated by the identification information stored in the wireless tag, and the biometric information read by the biometric information reading unit is authenticated by the biometric authentication information of the wireless tag. Authentication, the management of the handler can be performed strictly, and security can be ensured.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing an electronic apparatus according to a first embodiment of the present invention.

  As shown in FIG. 1, the electronic device 1 according to the present embodiment includes an RFID receiver (wireless tag receiver) 11 that receives information stored in the RFID tag 2 through wireless communication, and an RFID receiver 11 receives the information. It has an RFID control unit (wireless tag control unit) 12 for determining whether the owner of the RFID tag 2 is registered as a device handler based on the information and a key with a built-in fingerprint sensor (biological information reading unit) 13a. An operation unit 13 for performing input operations such as settings and commands by a user, a fingerprint sensor control unit (biometric authentication control unit) 14 for authenticating a handler based on fingerprint data read by the fingerprint sensor 13a, and a control for controlling each unit of the device. Part 15.

  The operation unit 13 of the electronic device 1 includes, for example, a POS terminal, an ECR, etc., a key (for example, a “total” key) that allows money to be taken in and out, and a terminal that can access a database of personal information, etc. A fingerprint sensor 13a is incorporated in a key to be pressed last after the operation of the electronic apparatus 1 is completed, such as a key for requesting access (for example, “ENTER” key), and the fingerprint of the pressed finger is read. ing.

  In addition, in a database (not shown), information on a person who is permitted to operate the electronic device 1 is stored using information for identifying an individual (personal ID (IDentification)) as a key. It can be searched. This database may be held in the electronic device 1 or may be accessible from the electronic device 1 via a network or the like.

  Further, the RFID tag 2 stores the personal ID of the owner of the RFID tag 2, the characteristic information (biometric information) of the fingerprint of the owner of the RFID tag 2, and the like. The feature information of the fingerprint is the information extracted only for the characteristic part in the fingerprint, and all of the characteristic parts may be stored, or a plurality of points may be selected from among them. It may be stored.

  The electronic device 1 authenticates the owner of the RFID tag 2 based on the information received from the RFID tag 2, and the operator who operates the electronic device 1 based on the fingerprint data read by the fingerprint sensor 13a is the owner of the RFID tag 2. It has come to verify.

  Specifically, when the operator who has the RFID tag 2 approaches the electronic device 1, the RFID tag 2 detects the radio wave transmitted by the RFID receiver 11, and sends the RFID tag 2 to the RFID receiver 11. Send the data stored in.

  When receiving data from the RFID tag 2, the RFID receiving unit 11 receives the personal ID of the owner of the RFID tag 2 or the characteristic information of the fingerprint of the owner of the RFID tag 2 from the received data as shown in the flowchart of FIG. Are read out and output to the RFID controller 12 (S11).

  Next, the RFID control unit 12 searches the database of operators who are permitted to operate the device based on the input personal ID (S12), and determines the search result (S13).

  If a personal ID that matches the input personal ID is not found as a result of the search, the RFID control unit 12 determines that the operation of the device is not permitted by the owner of the RFID tag 2, and the control unit 15 Operation impossible is output, the control unit 15 places the electronic device 1 in an operation impossible state (S14), and the process ends.

  As a result of the search, if a personal ID that matches the input personal ID is searched, the RFID control unit 12 outputs the input fingerprint characteristic information to the fingerprint sensor control unit 14, and the fingerprint sensor control unit 14 The characteristic information of the inputted fingerprint is temporarily stored (S15).

  Then, the fingerprint sensor control unit 14 waits for a key (for example, “total” key) including the fingerprint sensor 13a of the operation unit 13 to be pressed and for fingerprint data to be input from the fingerprint sensor 13a (S16).

  When a key containing the fingerprint sensor 13a is pressed and fingerprint data is input from the fingerprint sensor 13a, the fingerprint sensor control unit 14 compares the input fingerprint data with the stored fingerprint characteristic information and reads it. It is compared whether the fingerprint data matches the fingerprint of the owner of the RFID tag 2 (S17), and it is determined whether they match (S18).

  If the read fingerprint data does not match the fingerprint of the owner of the RFID tag 2, the fingerprint sensor control unit 14 outputs a business stop to the control unit 15, and the control unit 15 stops the business (S 19) and ends. .

  If the read fingerprint data matches the fingerprint of the owner of the RFID tag 2, the fingerprint sensor control unit 14 outputs an authentication OK to the control unit 15, and the control unit 15 executes the instructed operation (S20). ),finish.

  As described above, in the present embodiment, the owner of the RFID tag 2 is authenticated based on the information stored in the RFID tag 2, and the operator who operates the electronic device 1 matches the owner of the RFID tag 2. Since it is authenticated by the fingerprint, it is possible to strictly authenticate the handler, to strictly manage the handler, and to ensure security.

  In addition, since fingerprint comparison is performed by comparing the fingerprint feature information stored in the RFID tag 2 with the fingerprint data read by the fingerprint sensor 13a, the processing load due to fingerprint verification can be reduced. The time required for fingerprint verification can be reduced.

  Further, since the fingerprint sensor 13a is built in a key that is finally pressed after the operation of the electronic device 1 of the operation unit 13 is completed and the fingerprint data is read when the key is pressed, the fingerprint is read by the operator. The fingerprint data can be read without performing the operation to improve the operability.

  In the present embodiment, the personal ID stored in the RFID tag 2 is authenticated, and all the handlers whose fingerprint data read by the fingerprint sensor 13a is authenticated can execute the business. An authority may be set for each individual, an operation that can be executed for each authority is set, and an operation that can be executed according to the authority of the operator may be changed. With this configuration, it is not necessary to switch authority to select a specific task, and operability can be improved.

  In the present embodiment, the characteristic information of the owner's fingerprint is stored in the RFID tag 2, but it is stored in the database storing not the RFID tag 2 but the information of the operator who is permitted to operate the electronic device 1. You may keep it.

  As described above, the electronic device according to the present invention has the effect that it is possible to strictly authenticate the handler, to strictly manage the handler, and to ensure security, It is useful as a device that requires management by the operator or a device that requires security.
