Abstract
We propose a privacy preserving biometric based authentication protocol by which user can authenticate to different service providers from mobile phone, without involving identity provider in transactions, thus enhancing privacy. Authentication is based on a cryptographic identity token which embeds a unique, repeatable and revocable identifier generated from the user’s biometric image and a random secret, supporting two-factor authentication based on zero-knowledge proofs of knowledge. Our approach for generating biometric identifiers from users’ biometric is based on perceptual hashing and SVM classification techniques.
