Iris recognition system has demonstrated its strong capability in performing personal verification and identification with promising recognition accuracy. However, the conventional iris recognition system stores the unprotected iris templates in a database, which is potentially being compromised. Even though biometric template protection provides a feasible solution to secure biometric template, a trade-off between security and recognition accuracy is incurred. That is, the higher security level always trades with poor recognition accuracy and vice versa. In this paper, a new iris template protection scheme is proposed, namely “Indexing-First-One” (IFO) hashing. IFO hashing transforms the binary feature into index value with Jacaard distance preservation. The resultant template offers a good indication of inheriting similarity from the IrisCode and strong concealment of IrisCode against inversion attack as well as other major security and privacy attacks. Experiments on CASIA-v3 data set substantiate that the proposed scheme can achieve as low as 0.54 % equal error rate and well preservation of recognition performance before and after IFO hashing.
