This paper presents a model for watermarking and some attacks on watermarks. Given the watermarked signal, the so-called Wiener attack performs minimum mean-squared error (MMSE) es...

In this paper, an efficiently DWT-based watermarking technique is proposed to embed signatures in images to attest the owner identification and discourage the unauthorized copying...

Watermarking is to embed a structure called a watermark into the target data such as images. The watermark can be used, for example, in order to secure the copyright and detect tam...

Watermarks are the most important tool for dating old, not explicitly dated paper documents. Hence, catalogues and databases of watermarks play an eminent role for the work of med...

We introduce a new dynamic technique for embedding robust software watermarks into a software program using thread contention. We show the technique to be resilient to many semanti...

In this paper we present a scene-based video watermarking scheme using support vector machines (SVMs). In a given scene, the algorithm uses the first h′ frames to train an embed...
