The proliferation of networked authentication
systems has put focus on the issue of interoperability.
Fingerprint sensors are based on a variety of different technologies that introduce inconsistent distortions and variations in the feature set of the captured image, which makes the goal of interoperability challenging. The motivation of this
research was to examine the effect of fingerprint sensor interoperability on the performance of a minutiae based matcher. A statistical analysis framework for testing
interoperability was formulated to test similarity of minutiae count, image quality and similarity of performance between
native and interoperable datasets. False non-match rate (FNMR) was used as the performance metric in this research.
Interoperability performance analysis was conducted on each sensor dataset and also by grouping datasets based on the
acquisition technology and interaction type of the acquisition sensor. The lowest interoperable FNMR observed was 0.12%.
