With the advent of the Internet and multimedia technology,the multimedia communication has become more and more important,which makes research multimedia information and picture information and sound information.This paper discusses an image encryption algorithm based on chaotic binary sequences and improves algorithm of gray distance to evaluate the effect of binary image encryption.Experiment on chaotic sequence sensitivity on their initial condition,the scrambling of distance pixels,and the encrypting and de encrypting speed of images.The result shows that the encryption algorithm effect is good and has low computational complexity and high security.
