In “Convenient Security”, Dave Crawshay-Hall surveys fingerprint sensing technologies. He presents a technical discussion of why sensor technology affects biometric performance, concluding that the traditional tension between convenience and security is a false choice:
The traditional way of looking at high-security applications is to sacrifice user convenience in order to keep the false accept rate at an acceptable level…. Multispectral imaging is a sensor technology that improves image quality to such a degree that it is possible to have a reasonably low FAR and FRR at the same operating point. Multispectral imaging technology is a game-changer. It pushes that ROC curve in.
