Zhu H et.al proposed an image encryption algorithm through 2D compound homogeneous hyper-chaotic system and local binary pattern . Belazi, A. and A. In general, chaos-based image encryption algorithms consist of two steps: pixel permutation and pixel diffusion. The pixel permutation changes pixel position, while the pixel diffusion alters pixel values where a change in a pixel will spread almost to other pixels of entire image. 9120d8e on Mar 24, 2016. … To enhance the level of security, we use wavelet packet transform to decompose and filter the signal. The image encryption algorithm includes two steps: Firstly, the positions of the pixels of the original image are shuffled by Arnold cat map.
