Abstract:
[Problem] To provide a user authentication technology whereby hacking of a system by a third party is effectively prevented. [Solution] The present invention is a user authentication method and system, wherein: an information communication terminal allocates numerals, etc., which configure a token code which is generated by time synchronizing with an authentication system side to each cell which configures a user's password derivation pattern, and displays upon a user interface a personal identification table whereupon numerals, etc., are allocated which have been randomly generated with other cells; the user, with reference to the personal identification table, selects the numerals, etc., which are allocated to each cell which configures the user's password derivation pattern, and inputs same as a password; and the authentication system carries out an authentication determination upon the inputted password on the basis of the generated time synchronized token code.
