PROBLEM TO BE SOLVED: To provide a convinient authentication environment in which any security hole does not exist, a service providing side can check an authentication system and authentication algorithm is easily updated. SOLUTION: In the system connecting a user side terminal 1 and a center side device 7 through a network 11, when performing personal authentication by using human body information, the user side terminal 1 extracts features from the human body information and transmits data showing the features to the center side device 7 and the center side device 7 performs authentication by using the data and previously registered data. In this case, a program for feature extracting processing in the user side terminal is enciphered and transmitted to the user side terminal by the center side device. Besides, the data showing the features are scrambled and transmitted to the center side device by the user side terminal. As human body information, a fingerprint or handwriting can be used. |
