PROBLEM TO BE SOLVED: To authenticate a person oneself by using both biological authentication including a fingerprint or the like and terminal device (stick) authentication. SOLUTION: In this ID stick system, by reading the fingerprint by a fingerprint authentication-equipped and chip USB 6, individual authentication is performed in the first stage. In the second stage, random number data of a random pulse are transmitted to a PC or an authentication server, and the authentication of a terminal device (a stick) is performed. At that time, because it is possible to perform false recognition at the probability of 1/10,000, a confirmation signal is sent to the stick terminal from the authentication server, and the authentication of the terminal device is performed after confirmation. Thereby, the authentication of 100% becomes possible. A random pulse signal has a function not capable of generating the same key by replacing the random pulse spontaneously generated by a special chip by data as a random number and setting them as a cardinal number of encryption. Accordingly, falsification of data or decryption of the encryption by a malicious third party becomes impossible 100%. COPYRIGHT: (C)2007,JPO&INPIT |
