<p><P>PROBLEM TO BE SOLVED: To provide a technique capable of performing authentication using only one authentication device while effectively preventing unauthorized use of a computer. <P>SOLUTION: In the authentication program, based on authentication information input by a user's operation, whether input of normal or illicit information by the user's operation is performed as preset or not is determined. The determination processing is repeated twice or more, and when it is determined in all the determination processing that the input by the user's operation is performed as it is set, the user concerned is authenticated. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
