INDIVIDUAL AUTHENTICATION APPARATUS,INDIVIDUAL AUTHENTICATION METHOD,AND COMPUTER PROGRAM

摘要

An authentication apparatus capable of authentication based on a normal user operation. Authentication is executed according to normal operation information to an information processor. Information on the operation performed to an input apparatus by a user, for example, the keyboard input state is fetched as the operation information and compared to the operation information registered in a database, thereby performing authentication. Thus, authentication can be performed without performing a particular input process for authentication by the user. Moreover, authentication is performed by considering a plurality of operation information items and data with little irregularity is weighted for cross−reference, thereby enabling a highly−accurate user authentication.
