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...
We propose a blind watermarking technique to embed multiple watermarks simultaneously. It allows the use of correlated key to embed multiple watermarks. A dual-key system is used ...
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...
The recent proliferation of digital multimedia content has raised concerns about authentication mechanisms for multimedia data. A number of authentication techniques based on digi...
In this paper we introduce the idea of using Computer Vision techniques for improving and enhancing watermarking capabilities. Specifically, we incorporate Geometric Hashing techn...
