Application And Study Of Text Digital Watermarking On Copyright Protection

This paper is mainly about digital watermarking, focusing on the text digital watermark in the application of copyright protection issues. On the basis of introducing the definition,function and method of digital watermarking, analysise, compare algorithms and modesl of the existing text digital watermarking,and propose a new digital watermarking algorithms according to the characteristics of information hiding and digital watermarking.Considering algorithms and models of the existing digital watermarking, on the basis of the actual situation and own in-depth study,propose a more practical and more generic digital watermarking model.In the course of studying digital watermarking,firstly introducing basic concept and the existing algorithms of digital watermarking, then summary and analyze the strengths and weaknesses the existing digital watermarking,and propose a more practical,safer digital watermarking algorithm according to reality, including embedding algorithms and extraction algorithm.At the same time combined with copyright protection and other technical means,proposing an integrated digital watermarking system that is greater in capacity,smaller in visual impact, stronger in anti-attack capability,and that not only protect the copyright of digital works,but also protect their integrity.
