This work explores the problem of using biometric data to achieve non-transferability of anonymous credentials; that is, sharing of anonymous credentials, which allow one to anonymously authenticate, can be severely limited if their use requires possession of the credential owner's biometric. We target to provide strong security guarantees using minimal trust assumptions, namely that a fresh reading of a biometric is enforced on each use of the credentials. Furthermore, no biometric or other information is compromised if an adversary obtains full access to all credential-related data. Our solution relies on constructions for fuzzy extractors that allow one to extract and reproduce a random string from noisy biometric images. We first examine security requirements of biometric key generators, and then show how they can be integrated with anonymous credentials to achieve a high degree of non-transferability and security.
