- Abstract
Image encryption is a useful technique of multimedia security and has been widely used in content protection, image authentication, data hiding, and so on. In this paper, we investigate the use of projection partition in image encryption, and then design an efficient image encryption algorithm based on random projection partition and chaotic system. Specifically, our algorithm randomly divides the input image into overlapping blocks. For each block, our algorithm further divides it into a set of projection lines. And then, chaotic system is exploited to generate a secret data pool. Finally, data encryption is done by random projection line swapping and XOR operation between projection line and secret sequence selected from the secret data pool. Many experiments are conducted to validate efficiency of our algorithm. Comparisons are also done and the results show that our algorithm is better than some popular algorithms.
