An authorization management system and method can be provided.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a diagram for explaining the configuration of the admission permission management system 1. The entrance permission management system 1 is installed on the entrance side of a room 900 that is a management area, and includes a reader / writer 510 for communicating with an IC card and a gate device 500 having an electric key 521 that needs to be unlocked when the door 910 is opened. The employee card 300 that is a permission card possessed by a user (here, an employee) who has been previously permitted to unlock the electric key 521 of the gate device 500 and the unlocking of the electric key 521 of the gate device 500 are permitted in advance. It consists of a visitor card 100 possessed by a visitor who is not.

From here, when the employee card 300 and the visitor card 100 are not particularly distinguished, they are simply referred to as an IC card.

The employee card 300 and the visitor card 100 store a card number for identifying each IC card, and the gate device 500 has a card number of the employee card 300 possessed by an employee permitted to unlock the electric key 521. Is remembered.

When issuing the visitor card 100, the gate device 500 requires authentication of an employee who is permitted to unlock the electric key 521 in advance, and the employee is authenticated by authenticating the employee card 300. The gate device 500 reads the card number from the employee card 300, and checks whether the read card number is the card number of the employee card 300 possessed by the employee who is permitted to unlock the electric key 521. Authenticate 300. If the employee card 300 is successfully authenticated, the electric key 521 is unlocked.

When the gate device 500 detects the visitor card 100 immediately after the electric key 521 is unlocked using the employee card 300, the gate device 500 temporarily uses the temporary key to unlock the electric key 521. The key data is written to the visitor card 100, and the electric key 521 using the visitor card 100 can be unlocked temporarily.

From here, the procedure in which the gate apparatus 500 issues the visitor card 100 in the admission permission management system 1 is demonstrated. FIG. 2 is a flowchart showing a procedure in which the gate device 500 issues the visitor card 100.

The gate device 500 needs to authenticate the employee card 300 when issuing the visitor card 100. The gate device 500 repeatedly transmits an initial response command (for example, a polling command described in the ISO / IEC14443 standard) to detect an IC card existing in the detection range of the reader / writer 510 on the entrance side.

The gate device 500 receives the response of the initial response command from the IC card, reads the card number from the detected IC card, and confirms whether the read card number is a card number registered in the gate device 500 in advance. Then, it is confirmed whether the detected IC card is the employee card 300, and the employee card 300 is authenticated (S1).

When the card number is included in the response of the initial response command, the gate device 500 does not perform the operation of reading the card number from the detected IC card. Further, in the present embodiment, the gate device 500 authenticates the employee card 300 using the card number, but key data is stored in the employee card 300 in advance separately from the card number, and the gate device 500 May authenticate the key data stored in the employee card 300.

When the authentication of the employee card 300 is successful, the gate device 500 unlocks the electric key 521 (S2), and starts a detection operation of a passerby passing through the door 910 (S3). Note that the gate device 500 locks the electric key 521 after a certain time has elapsed after unlocking the electric key 521, and if a passer-by of the door 910 is detected, there is a passer-by of the door 910. Is held until this procedure ends.

When the electric key 521 is unlocked and the detection operation of the passerby of the door 910 is started, the gate device 500 repeatedly transmits the initial response command, so that the IC card existing in the detection range of the reader / writer 510 on the entrance side is detected. Perform detection operation.

The gate device 500 receives the response of the initial response command from the IC card, reads the card number from the detected IC card, and confirms whether the read card number is a card number not registered in the gate device 500 in advance. Thus, it is confirmed whether the detected IC card is a visitor card (S4).

The gate device 500 measures the time from the start of the IC card detection operation, and when the visitor card 100 cannot be detected within a certain period (for example, until the electric key 521 is locked). This procedure is terminated without issuing the visitor card 100.

When the gate device 500 detects the visitor card 100, the gate device 500 refers to the flag described above to check whether there is a passerby who has passed through the door 910 (S5). This procedure ends without issuing, and if there is no passerby of the door 910, the process proceeds to S6.

The reason why the gate device 500 confirms whether or not there is a passerby of the door 910 before issuing the visitor card 100 is to prevent the visitor card 100 from being illegally issued. The absence of a passer by the door 910 means that the employee who has the authenticated employee card 300 does not pass through the door 910 and stays on the entrance side of the door 910. Can be prevented from being issued.

When the gate device 500 confirms the passerby of the door 910, the gate device 500 generates temporary key data to be written on the visitor card 100 and temporary key authentication data which is information for authenticating the temporary key data to be written on the visitor card 100 ( S6).

When generating the temporary key data and the temporary key authentication data, the gate device 500 writes the temporary key data to the visitor card 100 and stores the temporary key authentication data (S7). The generated temporary key authentication data is stored in the gate device 500 in association with the card number read from the visitor card 100.

In addition, the gate device 500 transmits a command message in which the generated temporary key data is written in association with the gate number of the own device to the visitor card 100 and stores the generated temporary key data in the visitor card 100 in association with the gate number. Let When the generated temporary key data is associated with the gate number and stored in the visitor card 100, a record having temporary key data as data may be written in the visitor card 100 using the gate number of the own device as a tag.

When the gate device 500 writes the temporary key data to the visitor card 100 and stores the temporary key authentication data, the procedure for issuing the visitor card 100 ends.

Based on the flow illustrated in FIG. 2, immediately after unlocking the electric key 521 using the employee card 300, the visitor card 100 is held over the reader / writer 510 of the gate device 500, thereby temporarily holding the visitor card 100. Data is written and the electric key 521 can be unlocked using the visitor card 100.

If the temporary key data written in the visitor card 100 is deleted when the visitor leaves the company, unauthorized use of the visitor card 100 can be prevented.

FIG. 3 is a flowchart showing a procedure when the gate device 500 unlocks the electric key 521. In order to unlock the electric key 521, the gate device 500 repeatedly transmits an initial response command, and performs an operation of detecting an IC card existing in the detection range of the reader / writer 510 on the entrance side.

By receiving the response of the initial response command from the IC card, the gate device 500 detects the IC card existing in the detection range of the reader / writer 510 on the entrance side, and when detecting the IC card, the gate device 500 detects the IC card. The card number is read from the IC card (S10).

As described above, when the card number is included in the response of the initial response command, the gate device 500 does not need to perform the operation of reading the card number from the detected IC card.

When the card number is read from the IC card, the gate device 500 checks whether the read card number is a card number registered in the gate device 500 (S11). If the read card number is the card number registered in the gate device 500, the gate device 500 determines that the detected IC card is the employee card 300, and proceeds to S14, where the gate device 500 unlocks the electric key 521. . If the read card number is not the card number registered in the gate device 500, the gate device 500 determines that the detected IC card is the visitor card 100, and proceeds to S12.

When the gate device 500 determines that the detected IC card is the visitor card 100, the gate device 500 detects the temporary key data associated with the gate number of the own device from the visitor card 100. Read from 100 (S12).

In order to read out the temporary key data associated with the gate number of the own device, the gate device 500 transmits a command message for reading out all the temporary key data to the visitor card 100 and is stored in the visitor card 100. All the temporary key data is read, and it is confirmed whether the temporary key data associated with the gate number of the own device is present in the read temporary key data.

If the temporary key data of the own device is not stored in the visitor card 100, this procedure is finished without unlocking the electric key 521, and the temporary key data of the own device is stored in the visitor card 100. If yes, go to S13.

When the temporary key data of the own device is stored in the visitor card 100, the gate device 500 reads out from the visitor card 100 using the temporary key authentication data corresponding to the card number read out from the visitor card 100. By authenticating the temporary key data, the legitimacy of the visitor card 100 is verified.

If the temporary key data authentication is successful, the process proceeds to S14, where the gate device 500 unlocks the electric key 521, and if the temporary key data authentication fails, this procedure ends without unlocking the electric key 521.
