This paper presents a method of digital image watermarking that is robust against compression and manipulation based on Adaptive Tabu search. Based on Adaptive Tabu search for finding the region of interest image that usually contains high level of information. Embed watermark in region of interest image (ROI) means better changes of surviving against compression and manipulation . Process time can be saved by selecting of region of interest image and embedding watermark in spatial domain. We use Adaptive Tabu search for finding region of interest. Wavelet transform is proved to be a suitable transformation for selecting appropriate subband for watermarking against compression and manipulation . For security, the watermark bits are randomly permuted before being embedded to the image. Only the owner knew the key randomization which is implemented by Convolution code. The experimental results confirm the validity of the proposed strategy.
