We introduce a novel method for secure computation of biometric hash on dynamic hand signatures using BioPhasor mixing and 2 discretization. The use of BioPhasor as the mixing process provides a one-way transformation that precludes exact recovery of the biometric vector from compromised hashes and stolen tokens. In addition, our user-specific 2 discretization acts both as an error correction step as well as a real-to-binary space converter. We also propose a new method of extracting compressed… CONTINUE READING

Key Quantitative Results

  • Our results show that the proposed method could produce stable and distinguishable bit strings with equal error rates (EERs) of 0% and 9.4% for random and skilled forgeries for stolen token (worst case) scenario, and 0% for both forgeries in the genuine token (optimal) scenario.
