Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A peripheral device for inputting information and allowing access to a computer system by a user, the computer system including a main housing for housing computer processing circuitry, the device comprising: a peripheral housing separate from the main housing, said peripheral housing being arranged to contain at least one switching device for generating input information; fingerprint acquisition means selectively operable for providing a user fingerprint signal representative of the fingerprint of a user; peripheral processing circuitry disposed within said peripheral housing for processing said user fingerprint signal; and comparison circuitry disposed within said peripheral housing and coupled to said peripheral processing circuitry for comparing said processed user fingerprint signal with authorized fingerprint signals to allow access to computer system by the user when predetermined criteria are satisfied.
Claim 2
Dependent Claim
127 words
A peripheral device for inputting information and allowing access to a computer system by a user, the computer system including a main housing for housing computer processing circuitry, the device comprising: a peripheral housing separate from the main housing, said peripheral housing being arranged to contain at least one switching device for generating input information; fingerprint acquisition means selectively operable for providing a user fingerprint signal representative of the fingerprint of a user; peripheral processing circuitry disposed within said peripheral housing for processing said user fingerprint signal; and comparison circuitry disposed within said peripheral housing and coupled to said peripheral processing circuitry for comparing said processed user fingerprint signal with authorized fingerprint signals to allow access to computer system by the user when predetermined criteria are satisfied.
Claim 3
Dependent Claim
19 words
The invention as set forth in claim 1 wherein said peripheral device is movable relative to the main housing.
Claim 4
Dependent Claim
63 words
The invention as set forth in claim 1 further including memory circuitry, said memory circuitry being coupled to said comparison circuitry, wherein said comparison circuitry being operable to compare said user fingerprint signal with authorized fingerprint signals in said memory circuit and to provide an access enable signal when said user fingerprint signal meets predetermined criteria with one of said authorized fingerprint signals.
Claim 5
Dependent Claim
40 words
The invention as set forth in claim 1 wherein said switching device is selectively operable by a user to input information to the computer system, said switching device and said fingerprint acquisition means having at least one common operative part.
Claim 6
Dependent Claim
57 words
The invention as set forth in claim 4 wherein said common operative part comprises a switching plate, said switching plate being operable by a user's finger to selectively provide a switch closure signal, said switching plate being simultaneously operable to provide an impression of the fingerprint of the user as an input to said fingerprint acquisition means.
Claim 7
Dependent Claim
55 words
The invention as set forth in claim 5 wherein said peripheral device further includes a light source within said peripheral housing and arranged to illuminate said switching plate from within said peripheral housing means, said peripheral device further including a light sensitive device responsive to said illuminated switching plate for providing said user fingerprint signal.
Claim 8
Independent Claim
125 words
A method for obtaining security clearance to enable a user to have access to one or more applications on a computer system, said computer system having a main housing and having a peripheral input device separate from said main housing for inputting information to said computer system, said peripheral input device housing memory circuitry and processing circuitry therein, said method comprising the steps of: (a) sensing a predetermined characteristic of a user's fingerprint using said mouse peripheral device; (b) producing a user identification signal representative of the sensed characteristic; (c) comparing said user identification signal with authorized user identification signals stored in said memory circuitry; and (d) providing a security clearance signal representative of the results of said step of comparing to said main housing.
Claim 9
Independent Claim
125 words
A method for obtaining security clearance to enable a user to have access to one or more applications on a computer system, said computer system having a main housing and having a peripheral input device separate from said main housing for inputting information to said computer system, said peripheral input device housing memory circuitry and processing circuitry therein, said method comprising the steps of: (a) sensing a predetermined characteristic of a user's fingerprint using said mouse peripheral device; (b) producing a user identification signal representative of the sensed characteristic; (c) comparing said user identification signal with authorized user identification signals stored in said memory circuitry; and (d) providing a security clearance signal representative of the results of said step of comparing to said main housing.
Claim 10
Dependent Claim
30 words
The invention as set forth in claim 7 wherein said characteristic is a fingerprint topography of the user, and said identification signal is a fingerprint signal representative of said topography.
