Enhanced Biometric Recognition for Secure Authentication Using Iris Preprocessing and Hyperelliptic Curve Cryptography
Algorithm 7: Proposed Iris Template Encryption (ITE).
Input: Original iris template I | Output: Encrypted iris template I’ | Process: | Choose genus 2 HEC using ECM | Convert original iris template to points in HEC | Convert all the points of HEC to divisors using PDC | Select random divisor e11 based on algorithm RCD | Select public key | For each 4 consecutive samples (I1, I2, I3, I4) do | Form randomized divisor e1 using algorithm RCD | Calculate using DACA | Return all computed cipher divisors. | Convert cipher divisors to cipher points using DPC | Convert cipher points to cipher template | Store cipher template in database |
