Abstract
There is provided a fingerprint authentication method. The method includes a first step of acquiring measurement data for a part of a fingerprint, a second step of calculating a matching rate by comparing the measurement data with at least one of a plurality of registration data, a third step of determining whether the matching rate is equal to or greater than a threshold and whether the measurement data has been previously processed for an authentication, a fourth step of calculating a security level accumulation value based on a result of the third step, and a fifth step of determining whether the security level accumulation value is equal to or greater than a threshold. If NO in the fifth step, processes of the first to fifth steps are repeated. If YES in the fifth step, a success of the authentication is determined and outputted.
