The expansion of technology has made several simple ways to manipulate the original content. This has brought the concern for security of the content which is easily available in open network. Digital watermarking is the most suitable solution for the defined issue. Digital watermarking is the art of inserting the logo into multimedia object to have proof of ownership whenever it is required. The proposed algorithm is useful in authorized distribution and ownership verification. The algorithm uses the concept of AC prediction using DCT to embed the watermark in the image. The algorithm has excellent robustness against all the attacks and outperforms the similar work with admirable performance in terms of Normalized Correlation (NC), Peak Signal to Noise Ratio (PSNR) and Tamper Assessment Function (TAF).Keywords
