The progress in computer network technology, processing, reproducing and distribution of digital images has becomes very easy. Apart from its advantages, it also gives an opportunity to the attacker or illegal user. Two major approaches available to protect digital images are watermarking technique and encryption technique. This paper presents a combined watermarking and encryption method to further improve the security of the images. It uses Discrete Wavelet Transform (DWT)-Singular Value Decomposition (SVD) watermarking technique and chaotic encryption method. After embedding the two watermark images into the host image it is encrypted and transmitted. At the receiver side it is decrypted and the watermarks are recovered. Simulation results prove that the proposed method is simple and more secure.
