In this paper we propose a content based multibit watermarking method robust to print–scan
attack. A method to extract feature points, robust in terms of watermarking, is proposed. The …

In this paper, we propose a blind method to embed multibit watermarks in images, robust to
various attacks on geometry and print-scan process. For carrying the multibit information, a …

This paper proposes a methodology in designing a spatial watermark which is robust to
geometrical attacks. The proposed watermarking methodology is based on self-registering …

For most watermarking methods, preserving the synchronization between the watermark
embedded in a digital data (image, audio or video) and the watermark detector is critical to …

This paper presents a new approach for watermarking of digital images providing
robustness to geometrical distortions. The weaknesses of classical watermarking methods to …

Watermark attacks are first categorized and explained with examples in this paper. We then
propose a new image watermark attack called'Pixel Reallocation Attack'. The proposed …

Recently, we proposed a method for constructing a template for efficient temporal
synchronization in video watermarking. Our temporal synchronization method uses a state …

In this paper, a novel multi-channel image watermarking framework which is able to resist
geometric attacks is proposed, and a spatial domain watermarking scheme which benefits …

Synchronization is crucial to design a robust image watermarking scheme. In this paper, a
novel feature-based image watermarking scheme against desynchronization attacks is …

In this paper, we present two watermarking approaches that are robust to geometric
distortions. The first approach is based on image normalization, in which both watermark …
