Fingerprint identification security system
First Claim
1. A key-lock operated security system utilizing a fingerprint of an authorized user to control access to the security system comprising:
- a. an intelligent key comprising a mechanical key having an enlarged base end to be grasped between a thumb and forefinger of an authorized user and a narrow blade extending from the enlarged base end which can be inserted into and rotate a lock, said intelligent key having a fingerprint scanning means embedded in the surface thereof, and further having a microcontroller and a memory to provide an intelligent key for scanning and distinguishing between different fingerprints entirely within the intelligent key, wherein the scanning means is interfaced to the microcontroller which controls operation of the scanning means and reads data from the scanning means, to scan and correlate the minutia patterns of an individual fingerprint against one or more patterns of finger fingerprints of one or more authorized users of the security system stored within the memory, such that fingerprint recognition is performed entirely within the intelligent key, and the intelligent key having a data transmission means for transmitting encoded data signals indicating control functions in the security system;
b. said lock mechanically interfacing with the intelligent key when the intelligent key is inserted into the lock;
c. a key-lock controller for receiving and decoding the encoded signals from the intelligent key and in response thereto, controlling security functions of the security system.

Abstract
A key-lock operated security system utilizing a fingerprint of an authorized user to control access to the security system, such as the ignition system of an automobile. An intelligent key has a fingerprint scanning chip embedded in the surface thereof, and further has a microcontroller, a memory and electrical contacts to provide an intelligent key capable of scanning and distinguishing between different fingerprints. The scanning chip is interfaced to the microcontroller which controls the operation thereof and reads data from the scanning chip, to scan and correlate the minutia patterns of an individual fingerprint against one or more patterns of fingerprints of authorized users of the security system stored within the memory. A lock has electrical contacts which contact the electrical contacts on the intelligent key when the intelligent key is inserted therein, to provide electrical power to the circuitry of the intelligent key, and to enable a data signal to be transmitted from the intelligent key through the electrical contacts to a key-lock controller, which in response thereto controls security functions of the security system, such as the operation and control of the ignition system of an automobile.
