Abstract
When first biometric information is read with an ID number, a first authentication unit acquires second biometric information corresponding to the ID number from a first database, and authenticates when the first biometric information matches with the second biometric information. A transferring unit transfers the second biometric information from the first database to a second database when the authentication is successful. When the first biometric information is read without the ID number, a second authentication unit authenticates if at least one of the second biometric information in the second database matches with the first biometric information among.
Claims10
A biometric authentication device that performs a biometric authentication, the biometric authentication device comprising:
- a receiving unit that receives a request to identify an object to be authenticated, and determines whether the request is assigned to a one-to-one authentication or a one-to-N authentication according to whether or not the request includes an identification information of the object with first biometric information of the object;
- a first authentication unit that, when the request includes the identification information of the object to be assigned to the one-to-one authentication, acquires second biometric information corresponding to the identification information from a first database in which biometric information of all objects to be authenticated is registered, collates the first biometric information received with the acquired second biometric information, and makes an authentication successful when the first biometric information matches with the acquired second biometric information;
- a transferring unit that transfers, when the first authentication unit makes the authentication successful, the second biometric information used in the successful authentication from the first database to a second database and stores the transferred second biometric information in the second database;
- and
- a second authentication unit that, when the request does not include the identification information to be assigned to the one-to-N authentication, makes an authentication successful when there is at least one piece of biometric information matching with the first biometric information received among the transferred second biometric information stored in the second database.

A non-transitory computer-readable recording medium that stores therein a computer program for performing a biometric authentication, wherein
- the computer program causes a computer to execute a process comprising:
- receiving a request to identify an object to be authenticated;
- determining whether the request is assigned to a one-to-one authentication or a one-to-N authentication according to whether or not the request includes an identification information of the object with first biometric information of the object;
- first authenticating including, when it is determined that the request includes identification information to be assigned to the one-to-one authentication at the determining,
- acquiring second biometric information corresponding to the identification information from a first database in which biometric information of all objects to be authenticated is registered;
- collating the first biometric information received with the second biometric information acquired;
- and
- making an authentication successful when the first biometric information matches with the second biometric information;
- transferring, when the authentication is successful, the second biometric information used in the successful authentication from the first database to a second database;
- storing the transferred second biometric information in the second database;
- second authenticating including, when it is determined that the request does not include the identification information to be assigned to the one-to-N authentication at the determining,
- making an authentication successful when there is at least one piece of biometric information matching with the first biometric information received among the transferred second biometric information stored in the second database.

A biometric authentication device that performs a biometric authentication, the biometric authentication device comprising:
- a receiving unit that receives a request to identify an object to be authenticated, and determines whether the request is assigned to a one-to-one authentication or a one-to-N authentication according to whether or not the request includes an identification information of the object with first biometric information of the object;
- a first authentication unit that, when the request includes the identification information to be assigned to the one-to-one authentication, acquires second biometric information corresponding to the identification information from a database in which biometric information of all objects to be authenticated is registered, collates the first biometric information received with the acquired second biometric information, and makes an authentication successful when the first biometric information matches with the second biometric information;
- an identifier attaching unit that attaches an identifier to the second biometric information matching with the first authentication information in the database when the authentication by the first authentication unit is successful;
- and
- a second authentication unit that, when the request does not include the identification information to be assigned to the one-to-N authentication, makes an authentication successful when there is at least one piece of biometric information matching with the first biometric information received among the second biometric information to which the identifier is attached in the database.
