Digital Watermarking Technology for Copyright Protection of Network Multimedia Resources
摘要
Abstract
The more easily network multimedia resources are copied, tampered and used by illegal users, the more outstanding the prob-lem of copyright protection of network multimedia resources is. Digital watermarking technology gets more and more attention by scholars as a potential effective way to solve the problem of copyright protection of network multimedia resources. This paper discusses and analyzes the actuality and the tendency of copyright protection of network multimedia resources first and then proposes a novel handy and useful dig-ital watermarking method based on singular value decomposition for copyright protection of network multimedia resources. Experimental results show that the proposed method has fine transparency of the embedded watermark image and is strongly robust against attacks such as JPEG-compression, brightness and contrast adjustment. Thus, the proposed method is much fit for the copyright protection of network multimedia resources.关键词
