Advanced Signal Processing for Personal Image Encryption on Consumer Electronics

In this paper, an advanced signal encryption processing for personal image is developed, which provide a more secure way to protect the privacy of images transmitted through consumer electronics. A selected moving window is decided before operating the two main encryption stages, which divides the plain image into several sub-images. Shuffling pixels in binary is obtained in the permutation stage, and multi-level ciphering process, comprising cipher-data picking up as well as information hiding, asymmetric translation, is implemented in the diffusion stage. Simulation results show that the proposed advanced signal processing for image encryption is effective to protect the privacy of personal images.
