In this work we propose a novel H.264/CAVLC structure-preserving substitution watermarking algorithm. The proposed watermarking algorithm enables extremely efficient watermarking by simple bit substitutions. Furthermore our watermarking algorithm can be applied in applications scenarios, that require exact structure-preservation. The quality and robustness of the approach are in depth evaluated...

There is a need for real-time copyright logo insertion in emerging applications, such as Internet protocol television (IPTV). This situation arises in IP-TV and digital TV broadcasting when video residing in a server has to be broadcast by different stations and under different broadcasting rights. Embedded systems that are involved in broadcasting need to have embedded copyright protection. Ex...

The aim of this work is to produce a novel hybrid digital watermarking technique, based on the exploitation of both the RGB and the YCbCr colour spaces, using spatial domain techniques, to increase robustness to attacks. Results demonstrate that the proposed hybrid technique can withstand levels of geometric attacks and processing attacks up to a point where the commercial value of the images t...

Teleradiology plays a vital role in the medical field, which permits transmitting and imaging data over communication network. It ensures reliability provides convenient for clinical interpretation diagnostic purposes. The transmission of this network raises problems legal, ethical issues, privacy, copyright authenticity. protection images is significant issue field. Watermarking schemes are us...

Ceramic art is essential in interior design and decoration, making exquisite ceramic tiles imposes strict requirements for inkjet printing technology. High-resolution are often produced through printing, which the input images converted into a halftone format. However, traditional binary halftoning techniques cannot produce high-resolution ensuing process. Given that processes of high-temperatu...

Problem statement: The issue of having robust and fragile watermarking is still main focus for various researchers worldwide. Performance of a watermarking technique depends on how complex as well as how feasible to implement. These issues are tested using various kinds of attacks including geometry and transformation. Watermarking techniques in color images are more challenging than gray image...

Abstract Video piracy is a challenging issue in the modern world. Approximately $$90\%$$ 90 % of newly released films were illegally distributed around world via Internet. To overcome this issue, video watermarking an effective process that integrates logo frames as wat...

With the explosive growth of internet technology, easy transfer of digital multimedia is feasible. However, this kind of convenience with which authorized users can access information, turns out to be a mixed blessing due to information piracy. The emerging field of Digital Rights Management (DRM) systems addresses issues related to the intellectual property rights of digital content. In this p...

An entirely novel approach to image indexing is presented using content-based watermarking. The proposed system uses colorimage segmentation and watermarking in order to facilitate content-based indexing, retrieval and manipulation of digital images and image regions. A novel segmentation algorithm is applied on reduced images and the resulting segmentation mask is embedded in the image using w...
