33、he on-card biometric comparison paradigm. While the most common commercial realization of this capability has been the comparison of fingerprint minutiae templates on card, comparison of data from other modalities has been implemented also. Indeed the relevant card standards have been explicitly dra

34、fted to support arbitrary biometric modalities. Further information on modality-specific aspects can be found in ISO/IEC 19795-3. In any case, while the computational capability of such cards has increased in recent years, there remains the question of whether verification accuracy needs to be trade

35、d off for speed or data size or both. For fingerprint templates, the goal of improved efficiency has led to the development of the ISO/IEC 19794-2:2005 compact-size card formats specifically for on-card biometric comparison. This part of ISO/IEC 19795 specifies a mechanism for measuring both accurac

36、y and speed of ISO/IEC 7816 integrated circuit cards processing data from arbitrary modalities. It includes examples for the data structures and commands needed to match conformant ISO/IEC 19794-2:2005 minutiae templates on cards.
