Digital watermarking is a technique to protecting copyright of digital data. In this paper, we proposed a digital image watermarking scheme based on invariant wavelet domain. A watermark image is embedded into a host image via modular operations and can be extracted without resorting to the original image. Experiment results show that our scheme is robust enough to be against attacks, such as multiples of 90° rotation, jpeg compression, adding noise, blurring, and sharpening.
