摘要

With the vast increase in the utilization of biometric recognition, template preservation for biometrics captured attention in the recent years. Due to the irreversible nature of biometrics and the unsecure template management employed by these systems, security and confidentiality issues are raised. In order to address this issue, biometric template protection (BTP) was created. A non-invertible variant of BTP with movable templates is called cancellable biometrics. In this paper, presented cancellable biometric template protection with prior security authentication and by two novel approaches. The very first strategy is based on cancellable facial recognition and homomorphic filtering masking (HFM).The facial photos are subjected to the A Trous Transform (AT) algorithm in the second recommended approach. The picture is then split into seven subcarriers by the AT. The face recognition software uses the generated map, which is encrypted using the HFM encoding technique. Additionally, second phase authentication is applied at the verification phase to restrict the unauthorized access of the user. Moreover, the suggested method gives a respectable recognition rate and maintains the true geometric connections between the enrollment and inquiry templates even after modification. The results of experiments show that the suggested technique performs admirably in terms of recognition rate, computation time, confidentiality, diversity, non-repudiation, and non-invertibility, which are the main problems associated with the development of cancellable templates.
