In this paper, we focus on a step of the watermarking process whose importance has been disregarded so far. In this perspective, we introduce the vector extraction paradigm which i...

We present an asymmetric watermarking method for copyright protection that uses different matrix operations to embed and extract a watermark. It allows for the public release of a...
