PROBLEM TO BE SOLVED: To provide a user identifying device for reducing errors where an unauthorized use is decided as being the user himself. SOLUTION: At registering of a user, a presentation message constituted of the combination of a 'voice' and 'character' is selected from a message group (S3), and authentication data, constituted of the combination of a 'voice' and 'signature' and 'character', are registered in a dictionary (S4). At identifying of a user, the authorized user knows items to be inputted and the input method, while an unauthorized user does not even know what items to be inputted. Actually, the message is presented to the user, and promoted inputting of the authentication data is. When all the input data and the registered data are the same, it is deemed that there is 'succful identification'. |
