ABSTRACT:
A mouse computer input peripheral device includes a window area integrally constructed within the mouse and positioned at an area on the mouse upon which a user normally places a finger in operating the mouse. The mouse further includes an illuminating device and a light sensitive detection device for providing a user signature signal representative of the characteristics of the ridge and valley pattern of the fingerprint of a finger placed upon the window area. The signature signal is transmitted to the BIOS within the computer system in which the mouse is operating and compared with one or more stored patterns which have previously been authorized for access to the computer system. When the user's signature signal is compared with and matches one of the stored and approved signature signals, the system is enabled and the user is granted access.
