Abstract
A sensor acquires the same type of biometric information from plural fingers in association with an ID. A processor generates feature data used for verification from the biometric information, and generates characteristic data used for calculation of similarity between the plural fingers from the biometric information. Next, the processor compares the characteristic data and calculates the similarity between the plural fingers. The processor determines whether the feature data is registrable based on the similarity, and a memory stores the feature data in association with the ID when the feature data is registrable.
Claims9
A biometric information registration apparatus, comprising:
- a biometric information sensor configured to acquire a fingerprint image from a plurality of fingers in association with one ID;
- a processor configured to generate feature data used for verification from the fingerprint image, to generate characteristic data used for calculation of a similarity between the plurality of fingers from the fingerprint image, to calculate the similarity between the plurality of fingers by comparing the characteristic data, and to determine whether the feature data is registrable based on the similarity, the characteristic data indicating a size of a fingerprint of the fingerprint image, a likelihood of the fingerprint image being a type of fingerprint pattern, a quality of the fingerprint image, a width of a ridge of the fingerprint image, or a distance between ridges of the fingerprint image or any combination thereof;
- and
- a memory configured to store the feature data in association with the ID when the feature data is registrable.
A biometric information registration method, comprising:
- acquiring a same type of biometric information from a plurality of fingers in association with one ID;
- generating by a processor feature data used for verification from the biometric information;
- generating by the processor characteristic data used for calculating a similarity between the plurality of fingers from the biometric information, the characteristic data indicating a size of a fingerprint of the fingerprint image, a likelihood of the fingerprint image being a type of fingerprint pattern, a quality of the fingerprint image, a width of a ridge of the fingerprint image, or a distance between ridges of the fingerprint image or any combination thereof;
- calculating by the processor the similarity between the plurality of fingers by comparing the characteristic data;
- and
- determining by the processor whether the feature data is registrable based on the similarity and registering the feature data in a memory in association with the ID when the feature data is registrable.
A non-transitory computer-readable recording medium having stored therein a biometric information registration program causing a computer to execute a process comprising:
- acquiring a same type of biometric information from a plurality of fingers in association with one ID;
- generating feature data used for verification from the biometric information;
- generating characteristic data used for calculating a similarity between the plurality of fingers from the biometric information, the characteristic data indicating a size of a fingerprint of the fingerprint image, a likelihood of the fingerprint image being a type of fingerprint pattern, a quality of the fingerprint image, a width of a ridge of the fingerprint image, or a distance between ridges of the fingerprint image or any combination thereof;
- calculating the similarity between the plurality of fingers by comparing the characteristic data;
- and
- determining whether the feature data is registrable based on the similarity and registering the feature data in a memory in association with the ID when the feature data is registrable.
