Recently, chaos based encryption techniques introduce several merits over the classical techniques such as extensive security levels, complexity and fast speed. In this paper, a chaotic based cipher that incorporates both Logistic chaotic map and Tent map is proposed. An external biometric key of length 256-bits is employed to derive the initial seeds of the applied chaotic maps. In the encipher stage, the pixels information are masked based on an iterative structure using a data-dependent… Expand
