Image Hiding Technology Based on Low Dimensional Compound Chaos Algorithm

Jubao Qu, Hongtao Liang

Abstract


This paper proposes a low-dimensional compound chaotic algorithm to realize plaintext encryption and hide the encrypted text into the image. Because the texture DCT transform characteristics of the image are fully utilized, the embedded ciphertext has good masking and anti-attack ability. Experiments show that the proposed algorithm improves the security of hidden information and reduces the encrypting and decrypting time on the basis of maintaining the visual quality of the image.
