Digital Image Watermarking based on Successive Division

In this paper, successive division and concatenation based image watermarking scheme has been proposed. Successive division reduces the pixel intensity of watermark image in order to embed the same into host. Concatenation helps in embedding multiple images of watermark into host. After de-watermarking process, the multiple images of same watermark are filtered and unified to get the desired watermark. The watermarked images are subjected for various security attacks such as noise interference and cropping effects. The retrieved watermark gives high degree of similarity to the original watermark. From the security analysis, better results are obtained for the proposed algorithm compared to other existing techniques.
