Joint image compression and encryption method

摘要：

　　Joint encryption and compression method not only ensure the uniformity of the algorithm but also can enhance the security of algorithm,so it have very important practical significance.This paper studies the over complete dictionary of DCT and OMP algorithm,uses the two kinds of common chaos mapping and learns China remainder theorem.Then one joint image compression and encryption algorithms using chaos map,sparse decomposition and Chinese remainder theorem is proposed to realize image compression and encryption.The experimental results show that the algorithm realizes information transmission requirements in security and efficiency,and achieves the desired requirements.
