<p><P>PROBLEM TO BE SOLVED: To provide an authentication apparatus and program which facilitate user's input operation of a password character string and more surely prevent the leakage of the password character string thereby excluding spoofing by a third person. <P>SOLUTION: When the distribution of a login screen is requested from a terminal, the authentication apparatus causes a display of a terminal to reproduce and display a moving image in which the display positions of image portions corresponding to individual characters "0" to "9" usable for a password are changed with the lapse of time like (B) to (F), causes a user to perform input operation for repeating click operation for clicking a display position of a circle in the moving image corresponding to a specific character in the password successively from a top character of the password and receives click information expressing operation time and the click position from the terminal in each execution of the click operation. The authentication apparatus recognizes an input password on the basis of the click information receiving time and the click position and recognizes an input password on the basis of the operation time and the click position, and when both passwords coincide with a formal password, authentication success is assumed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
