Advanced face recognition system using chaos cryptography and haar wavelet

Recently, face recognition systems with extra features gain high attention than classical ones. Although, there are various attacks for breaching typical systems, one of the most malicious attacks is evoking the face pattern when transferring over non-secure channels to compromise user's privacy forever. Thus, the introduced protection routine based on mixture of chaos maps offers much speedy ciphering methodology and more robustness against malicious attacks. A complete security examination is achieved to confirm the secrecy of the face identifier. It introduces a remarkable improvement in key sensitivity plus introducing large key space and being more robustness against different malicious attacks. Moreover, being noninvasive to the identification process, matching the decrypted templates offers 97% for authentication plus creating efficient renewable secure sketches.
