Keyboard Apparatus for Personal Identification

When a user of a data processing system accesses the system through a terminal keyboard, it is common to identify the user in order to verify that he has authority to make the access. For example, the user may key in a secret code word.

To simplify this procedure, a keyboard is provided with means for sensing the time pattern and the key pressure, as a user keys in a standard entry code. These patterns are characteristic of an individual user, in much the same way that the pattern of a telegraph signal is characteristic of the telegraph key operator.

When an initial user of the system first enters the code, the time and pressure characteristics are recorded by the system. Thereafter, the user enters the system by keying in the standard entry code and other information, such as an individual identification. The system compares the entry code with the reference pattern and identifies the user.

The system can be variously modified for a selected security level, by choosing an appropriate length for the standard entry code and the degree of match that is required.
