Journal Article
A joint color image encryption and compression scheme based on hyper-chaotic system
2016
Overview
For the low security and compression performance of the existing joint image encryption and compression technology, an improvement algorithm for joint image compression and encryption is proposed. The algorithm employs the discrete cosine transformation dictionary to sparsely represent the color image and then combines it with the encryption algorithm based on the hyper-chaotic system to achieve image compression and encryption simultaneously. Through the experimental analysis, the algorithm proposed in this paper has a good performance in security and compression.
