Abstract:
A biometric factor augmentation method for an established, token-based identification system comprising the steps of:Splicing into a data stream between a token reader and a control panel of the token-based identification system such that there is an input splice end and an output splice end; Installing a biometric identification system between the input splice end and the output splice end, the biometric identification system having at least a biometric reader and a biometric search engine; Performing a biometric enrollment process to build a database of enrollment templates; Connecting the input splice end so that the data stream may be transmitted from the token reader to the biometric reader; Connecting the output splice end so that the data stream is capable of being re-transmitted from the biometric reader to the control panel; Intercepting an acquired token factor transmitted by the token reader through the data stream, the point of interception being substantially where the input splice end connects to the biometric reader; Utilizing the interception of the acquired token factor to electronically trigger the biometric reader to prompt a user to present a biological characteristic so that the biometric reader can perform a scan and create a biometric inquiry template; Performing a data match analysis of the inquiry template against at least one enrollment template located in the database of enrollment templates accessed by the biometric search engine; and Re-transmitting the data stream through the output splice end when the data match analysis matches an authorized user's enrollment template to the acquired inquiry template.
