Facial Template Protection Using Extended Visual Cryptography And Chaotic Encryption

ABSTRACT Protection of biometric data is of prime importance now a days. In this paper a new method is proposed for the protection of biometric facial data using visual cryptography and chaotic encryption. By using visual cryptography each private face image is decomposed into two public host images. The original image gets revealed only when both of these images are available simultaneously. By using chaotic encryption extra protection as well as privacy is ensured for these images. Chaotic encryption is applied onto each share. Any system having chaotic behaviour is used for getting values for encrypting the shares. Here 1D logistic map is used.
