Watermarking is the process of embedding watermarks into an image such that the embedded watermark can be extracted later. Lossy compression attacks in digital water-marking are one of the major issues in digital watermarking. Cheddad et al. proposed a robust secured self-embedding method which is resistant to a certain amount of JPEG compression. Our experimental results show that the self-embedding method is resistant to JPEG compression attacks and not resistant to other lossy compression attacks such as Block Truncation Coding (ETC) and Singular Value Decomposition (SVD). Therefore we improved Cheddad et al's. method to give better protection against ETC and SVD compression attacks.
