Abstract
In view of the digital image in the process of transmission, it is easy to leak information, in order to protect the security of image information. This paper proposes an image encryption method which is a combination of image sharing technology and chaos theory. First, dividing the secret image into blocks and coding the blocks, restructuring the blocks by pseudo random sequence which is generated by Logistic chaotic map; Then, processing the restructuring image by the image sharing technology; Finally, the images those be processed by image sharing are embedded into the cover image for network transmission. The experimental results show that the method can be better for digital image encryption.
