Patent ID: 7274807

Claim:
A method for matching biometric data on a smart card including the steps of: providing a smart card having biometric template data stored thereon; providing a host processor in communication with the smart card; providing a sensed biometric image to the host processor; providing co-ordinate data relating to a plurality of non-contiguous features of the template data from the smart card to the host processor, wherein the non-contiguous features of the template data include minutia recorded within the template and false features for which data is other than stored within the template; extracting other data from the biometric image, the other data for correlation with the provided co-ordinate data; aligning the biometric image within a known frame of reference relative to the template data on the basis of the provided co-ordinate data and the other data; extracting biometric data from the biometric image, the biometric data within a known frame of reference; and providing the biometric data to the smartcard for matching with the biometric data stored on the smart card.
