ABSTRACT

This paper presents a robust digital image watermarking technique. The proposed technique uses a circularly symmetric watermark to embed it into an image. Watermark is embedded in the middle frequencies of DFT domain. To make watermark less visible in spatial domain multiplicative embedding rule is used. This method is resistant to JPEG compression, filtering, noise addition and cropping. Results prove the robustness of this method against the above-mentioned attacks.
