Abstract
In order to strengthen the security of standard JPEG format color images in network transmission, this paper proposes a kind of JPEG color image encryption algorithm which combines the efficient and stable compression encoding with encrypting selectively. First, it selects out mapping better chaotic characteristics as a pseudo-random number generator, and uses the generated chaotic sequence for the encryption algorithm. Then, it uses the edge detection algorithm to find the blocks with rich image contour information, which provides a basis for selection and encryption of later images. It Encrypts the quantized image coefficients and embeds in the important block information. The experimental results shows that the algorithm in this paper can hide the color information and contour information of the plaintext image effectively. At the same time, the key is more sensitive. Compared with the classic encryption algorithm AES, it has better performance in terms of time complexity and encryption quality.
