Transform domain robust image-adaptive watermarking: Prevalent techniques and their evaluation

In today's world a lot much of the intellectual work is produced and distributed in the digital form and thus it becomes very difficult to prove the ownership claim by the legitimate owner and to stop the unauthorized use of the intellectual property. Robust watermarking provides solution to this problem. In this paper, we have categorized the popular techniques of transform domain robust image-adaptive watermarking techniques and provided a brief review of them. We have evaluated some prevalent watermarking schemes based on their robustness against common watermarking attacks. We have also discussed about the future research directions for the transform domain robust image-adaptive watermarking.
