<p>PROBLEM TO BE SOLVED: To provide an authentication system, which is capable of detecting the fact that feature information generated based on biological information is fabricated on a communication path, for performing personal authentication on the basis of the biological information, a client terminal, an authentication server, a terminal program and a server program.SOLUTION: The authentication system comprises a client terminal 1 connected through a network and an authentication server 51, and the authentication server 51 performs biological authentication. The client terminal 1 generates, from one piece of biological information, multiple pieces of feature information including first feature information and second feature information including first determination information (S102) and transmits authentication information to the authentication server 51 (S103). The authentication server 51 receives the authentication information (S111) and determines whether the authentication information is fabricated (S112).</p> |
