We proposed a blind watermarking technique to embed the watermark in JPEG compressed domain. Low frequency DCT coefficients are extracted to form an M-dimensional vector. Watermar...
A drawback of most watermarking techniques is the need for some additional information in order to retrieve the watermark. Additionally, the robustness of the watermark decreases ...
This paper aims to design robust correlation-based watermarking methods for images. We rst present a model of watermark embedding and extracting processes and carry out their ana...
The recent proliferation of digital multimedia content has raised concerns about authentication mechanisms for multimedia data. A number of authentication techniques based on digi...
We lay out a theoretical framework to evaluate watermarking techniques for intellectual property protection (IPP). Based on this framework, we analyze two watermarking techniques ...
