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.
