"BIOMETRIC FACTOR ENHANCEMENT METHOD FOR A SHEET BASED IDENTIFICATION SYSTEM". The most preferred method for extending an existing chip-based identification system is to mend in a data stream transmitted from a chip reader to a control panel such that a chip factor acquired from a user is intercepted. by a biometric identification or authentication system, which is serially inserted into a splice in the data stream. When the card reader transmits a data stream, such as a Wiegand interface, to the control panel, the data stream is used by the biometric identification system to guide the user to present an anatomical feature to a biometric reader. The biometric reader creates a biometric query model that is transmitted to a biometric search engine, along with the acquired card factor, such as a PIN or barcode, to perform data matching analysis against one or more models. associated with the acquired card factor. The search engine will match an authorized user or reject an unidentifiable user. If there is a match, then the data stream is allowed to pass from the biometric reader to the existing chip-based identification system control panel. The existing system does not need to be modified otherwise. The security of an Access Control System (ACS) can be greatly enhanced by this scaling method which preferably inserts an automatic fingerprint identification system (AFIS) into the data stream of an established ACS.
