Abstract
An authentication device includes a comparison unit and a determination unit. The comparison unit compares, with feature value master data for authentication, each feature value needed for authentication that has been extracted from a plurality of pieces of acquired biometric information. The determination unit determines not to provide authentication when, as a result of comparison by the comparison unit, there is no difference in each of the feature values that resulted in a mismatch.
Claims12
An authentication device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- compare, with feature value master data for authentication, each of a plurality of feature values needed for authentication, the plurality of feature values respectively having been
- extracted from a plurality of pieces of acquired biometric information;
- determine whether there is a difference among a plurality of mismatches in a feature value between the feature value master data and each of the plurality of feature values;
- and
- determine not to provide authentication in a case where there is no difference among the plurality of mismatches,
- wherein fraudulent authenticating by at least spoofing is prevented by determining not to provide authentication in the case where there is no difference among the plurality of mismatches.
An authentication method executed by a computer, comprising:
- comparing, with feature value master data for authentication, each of a plurality of feature values needed for authentication, the plurality of feature values respectively having been extracted from a plurality of pieces of acquired biometric information;
- determining whether there is a difference among a plurality of mismatches in a feature value between the feature value master data and each of the plurality of feature values;
- and
- determining not to provide authentication in a case where there is no difference among the plurality of mismatches,
- wherein fraudulent authenticating by at least spoofing is prevented by determining not to provide authentication in the case where there is no difference among the plurality of mismatches.
A non-transitory recording medium that stores a program
- for an authentication device that causes a computer to execute:
- comparing, with feature value master data for authentication, each of a plurality of feature values needed for authentication, the plurality of feature values respectively having been extracted from a plurality of pieces of acquired biometric information;
- determining whether there is a difference among a plurality of mismatches in a feature value between the feature value master data and each of the plurality of feature values;
- and
- determining not to provide authentication in a case where there is no difference among the plurality of mismatches,
- wherein fraudulent authenticating by at least spoofing is prevented by determining not to provide authentication in the case where there is no difference among the plurality of mismatches.
