Face Template Protection Algorithm Based on DNA Encoding Encryption

With the rapid development of information technology, biometric technology has been widely used. However, biological information is limited to everyone, once it is leaked, it can no longer be safely used, which will cause lifelong damage to users. Therefore, the study of biological template protection technology is of great significance. This paper introduces the deoxyribonucleic acid (DNA) coding theory into biometric template protection and proposes a face template protection algorithm based on DNA coding encryption. Experiments and analyses are carried out on Olivetti Research Laboratory (ORL) face database. The results show that the proposed algorithm not only enhances the security of the original template, but also ensures the recognition performance of the system.
