Digital Watermarking

This project seeks to develop a Robust Watermarking Software based on the research work carried out earlier. The group while exploring various watermarking techniques and algorithms that have been proposed for developing a Robust Watermarking Solution implemented a proposed Robust watermarking solution. A Robust Watermark is more resilient to the tempering/attacks that a multimedia object (Image, Video, and Audio) had to face like compression, image cropping, image flipping, image rotation to name a few. The group has implemented the solution A Second Order Spread Spectrum Modulation Scheme for Wavelet Based Low Error Probability Digital Image Watermarking. This scheme is proposed by D.A. Karras Chalkis Institute of Technology, Automation Dept. and Hellenic Open University, Rodu 2, Ano Iliupolis, Athens 16342, Greece. This software takes an Image as input and will apply the desired mark that one wishes to embed in the object according to the mentioned solution, so that it is not only invisible to the Human Visionary System but also strong enough to extract the original embedded mark to an extent that it is recognizable despite of the tempering/attacks. The group has worked under the guidance and supervision of Prof . The software works as a benchmarking tool for the proposed solution. The main purpose of this software is its use as test bed for the DWT based watermarking. Later it will become part of a larger system DWT based watermarking protocol.
