Secure Hamming Distrance based Biometric AuthenticationAuthors: Rohan Kulkarni,Anoop Namboodiri Conference: IAPR International Conference on Biometrics, 04-07 June 2013, Madrid, Spain. Date: 2013-06-04 Report no: IIIT/TR/2013/64 AbstractConcerns of privacy, template security and efficiency of biometric authentication systems have received consider- able research attention in the recent past. Binary template representations have been shown to provide significant im- provements in efficiency without compromising accuracy for a variety of biometric modalities including fingerprints, palmprints and iris. Most of the secure authentication pro- tocols work with generic feature representations or propose new secure templates for specific modalities. In this work, we propose an authentication protocol that works with any binary biometric representation that employs hamming dis- tance for comparison and convert it into a secure, privacy preserving protocol that provides template protection. We also provide the ability to use masks while computing the hamming distance. The protocol retains the accuracy of the underlying representation as demonstrated by our experiments.
