Secure watermarking scheme against watermark attacks in the encrypted domain ?
We have proposed a robust watermarking scheme in the encrypted domain. For traditional schemes, original media could be exposed to the embedder. The robustness of watermark in the encrypted domain should be taken into account. We investigate the watermark attacks that can be performed in the encrypted domain. Our watermarking scheme would be helpful for copyright protection in the cloud.
