Title:
AUTHENTICATION DEVICE, AUTHENTICATION METHOD AND PROGRAM STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2014/132570
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent a reduction in authentication accuracy caused by identity fraud. An authentication device (20) has a score calculation unit (30), a probability calculation unit (31) and a determination unit (32). The score calculation unit (30) compares each of a plurality of types of biological information, acquired as acquired biological information from the person whose identity is to be confirmed, to the same type of registered biological information registered in advance. Further, on the basis of that comparison, the score calculation unit (30) calculates (35) an authentication score that expresses the degree of similarity between the acquired biological information and the registered information, for each type of acquired biological information. For each type of the acquired biological information, the probability calculation unit (31) uses the calculated authentication score to calculate (38), as an identity fraud probability, the probability that the person whose identity is to be confirmed is fraudulently pretending to be the registered person who registered the registered biological information. The determination unit (32) uses the calculated identity fraud probabilities to determine whether the person whose identity is to be confirmed is the registered person, and/or to determine whether the person whose identity is to be confirmed is fraudulently pretending to be the registered person.
