A biometric data acceptance method allowing input biometric data obtained by an incorrect input operation not to be accepted. At least one reference biometric image is stored in a memory. A degree of similarity between an input biometric image and a reference biometric image is calculated. It is determined that the input biometric image is acceptable, when the degree of similarity is smaller than a predetermined threshold. If the degree of similarity is not smaller than the predetermined threshold, the input biometric image is not acceptable.
