Abstract:
Based on reg ion sh ifting encoding and p ixe lm apping, the pape r proposes im ag e encryption algor ithm. The image to be encrypted is div ided into several un its, and the positions of these un its are changed random ly. Then each unit is d isturbed by the p ixe lm apping, cutting the relations between the values of pix els in every un it. The a lgo rithm is based on the v irtues of the reg ion sh ifting and p ixe l mapp ing. The results o f computer simu la tion show that th is m ethod is flex ible in the freedom and strong in secrecy, especia lly for the binary im ag es and gray scale im ag es
