Information security is very important in modern society. Image encryption is a branch of information security. It can be not only used to protect the copyrights of the ownership of the images from the internet, but also to be used to image information hiding as a key pre-processing in order to increase the security. A novel image encryption method based on modular matrix transformation and coordinate sampling is presented in this paper. The algorithm has an advantage that images can be encrypted by their grey information and their coordinate information in the same time. As an application, the algorithm is used to image information hiding based on LSB. Experiments show that the method reaches a very good image encryption effect, and also can endure some image attacks.
