<p><P>PROBLEM TO BE SOLVED: To provide a password system using dynamic graphical images. <P>SOLUTION: The graphical images are arranged as a grid or matrix for presentation on a facial expression device for authentication of a user. The kinds of graphical images are derived from each of a designated authentication category and a non-authenticating category. A series of password elements corresponding to the graphical images are displayed with the graphical images. The user may enter the series of one or more password elements corresponding to graphical images from the authentication category which combine to form a password entry (14). An authentication server compares the password entry to an authentication password corresponding to the particular arrangement of the dynamic graphical images (16). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
