DIGITAL FINGERPRINT-BASED, OPT-IN BIOMETRIC AUTHENTICATION SYSTEMS

摘要

Devices, systems, and methods use captured image data of any part of a body as a source to form a digital fingerprint to biometrically identify the body. To protect privacy and prevent class-based profiling of people, a biometric authentication system does not preserve any class-based information or do any class-based discrimination. The digital fingerprint uniquely authenticates whether an individual being sampled is a particular previously sampled individual without having to establish an identity of the individual, and cannot be reverse-engineered to produce any information (e.g., a picture) that could be used to identify the individual (e.g., name) or the person's class, gender, race, or any other group information.
