An authentication processing apparatus for performing authentication based on a user's normal operation is provided. The authentication processing apparatus performs the authentication processing on the basis of operation information obtained from normally operating an information processing apparatus. Operation information obtained from operating an input unit by the user, such as a keyboard inputting mode, is obtained to serve as operation information, and the obtained operation information is checked against operation information registered in a database to perform authentication. Authentication is thus made possible without requiring the user to perform the special input processing for the authentication processing. Authentication is performed taking into consideration a plurality of pieces of operation information. With the checking processing in which less dispersed data is weighted, user authentication with high accuracy is made possible.

The present invention relates to individual authentication processing apparatuses and individual authentication processing methods, and more particularly to an individual authentication processing apparatus and individual authentication processing method for performing authentication based on an individual's operation characteristics included in normal keyboard operations by the individual for which authentication is performed and to a computer program.
One typical known individual authentication processing system performs authentication based on a key such as a password. FIG. 1 shows a processing sequence of a known authentication system for performing authentication by receiving a password at the time the processing on an information processing apparatus (for example, a PC) starts.
FIG. 1 shows time course in the abscissa axis and illustrates the processing performed in accordance with the flow of time. An authentication unit 101 performs the authentication processing. The authentication unit 101 is provided in the interior of an information processing apparatus used by unspecified users, such as a PC serving as a user terminal or an information terminal or financial terminal located in a public place, or a server connected with a network over which user input information can be transferred.
FIG. 1 is an illustration showing an example of a sequence of the known authentication processing and the user-operated input processing (example 1).
FIG. 2 is an illustration showing an example of a sequence of the known authentication processing and the user-operated input processing (example 2).
FIG. 3 is an illustration showing a sequence of the authentication processing and the user-operated input processing according to the present invention.
With reference to the drawings, an individual authentication processing apparatus and individual authentication processing method of the present invention will be described in detail.
Using FIG. 3, a processing sequence of an individual authentication processing apparatus according to an embodiment of the present invention will now be described. Similar to FIGS. 1 and 2 which have been described in the above description, FIG. 3 shows time course in the abscissa axis and illustrates the processing performed in accordance with the flow of time. An authentication unit 301 performs the authentication processing. The authentication unit 301 is provided in the interior of an information processing apparatus used by unspecified users, such as a PC serving as a user terminal or an information terminal or financial terminal located in a public place, or a server connected with a network over which user input information can be transferred.
The authentication unit 301 stores operation characteristic information on personal characteristics of user operations corresponding to a pre-registered user in a storage unit (database), and the stored information serves as authentication information. Specific modes of the authentication information are described in detail later. For example, various pieces of keyboard operation information include elapsed time data indicating elapsed time from a previous key input to a subsequent key input, time data indicating time during which a key is pressed, and time data indicating time from releasing a previous key to pressing a subsequent key. These various pieces of keyboard operation information are described in detail later.
