Biometric Factor Augmentation Method For Identification System
|
|
Abstract
|
The most preferred method ol augmenting an existing token-based identification system is to splice into a data stream transmitted Irom a token reader to a control panel such that an acquired token lactor from a user is intercepted by a biometric identification, or authentication, system that is wedged in series at a splice in the data stream. When the token reader transmits a data stream, such as a Wiegand interlace, to the control panel, the data stream is used by the biometric identification system to prompt the user to present an anatomical feature to a biometric reader. The biometric reader creates a biometric inquiry template that is transmitted to a biometric search engine, along with the acquired token lactor, such as a PIN or barcode, to perform data match analysis against one or more enrollment templates associated with the acquired token lactor. The search engine will either match an authorized user or reject an unidentifiable user. II there is a match, then the data stream is allowed to pass from the biometric reader to the control panel ol the existing token-based identification system. The existing system does not otherwise need to be modified. The security ol an Access Control System (ACS) can be greatly enhanced by this method ol augmentation that, preferably, wedges an automatic fingerprint identification system (APIS) into the data stream ol an established ACS
