Abstract
A secure and novel watermarking system based on complemented Maximum Length Cellular Automata (MLCA) and Two-Dimension Cellular Automata Transform (2D CAT) is proposed. In this watermarking scheme, the original watermark which is first encrypted by complemented MLCA with the private keys, and the encrypted watermark is embedded into the CAT domain of the cover image. Experiment results show that this new method is more secure and provides robust performance against watermarking attacks.
