Abstract
A method for matching biometric data on a smart card is disclosed. A smart card is provided having biometric template data stored thereon. A host processor in communication with the smart card is also provided. A sensed biometric image is provided to the host processor from an individual. From the smart card to the host processor, co-ordinate data relating to a plurality of non-contiguous features of the template data are provided. Other data is extracted from the biometric image, the other data for correlation with the provided co-ordinate data allowing for a subsequent alignment of the biometric image within a known frame of reference relative to the template data on the basis of the provided data and the other data. Once aligned, biometric data is extracted from the biometric image, the biometric data within the known frame of reference and then the extracted biometric data is transmitted to the smartcard.
