Because of multimedia information has huge amount of data and high redundancy, traditional encryption technology is not suitable for multimedia information encryption. Multimedia information encryption get great development when chaos appears. Chaos is very suitable for image encryption because of its many advantages. In this paper, I analysised the shortcomings of color image encryption algorithm based on 3D unified chaotic system, then aiming at the algorithm deficiency, I analysised the algorithm which improved by cat map, the security of the algorithm has been greatly improved.
