In this paper, we propose a watermarking method that does not requires an original image to extract embedded data. In our proposal, watermark information data are embedded by using the differences between the neighboring wavelet coefficients of the lowest band in the wavelet domain. Though such a concept have been already proposed by H.S. Kim et al., the original image is needed for extracting embedded data in their method. We developed a new scheme which does not requires the original image to extract embedded data, by modifying the embedding algorithm. Simulation results show that our proposed scheme indicates good picture quality in the watermarked image and robustness to some types of image processing attacks including JPEG compression.
