ePrint Report: Oblivious Extractors and Improved Security in Biometric-based Authentication Systems

Ivan De Oliveira Nunes, Peter Rindal, Maliheh Shirvanian

We study the problem of biometric-based authentication with template confidentiality. Typical schemes addressing this problem, such as Fuzzy Vaults (FV) and Fuzzy Extractors (FE), allow a server, aka Authenticator, to store “random looking” Helper Data (HD) instead of biometric templates in clear. HD hides information about the corresponding biometric while still enabling secure biometric-based authentication. Even though these schemes reduce the …
