The Design And Realization Of Digital Rights Encryption Management System Based On Watermarking

Digital copyright protection is a hot topic in the field of copyright protection, whichrelates to the protection of intellectual property, it has important theoretical research valueand broad application background. Digital copyright protection, mainly use digital rightsmanagement system, based on encryption, digital watermarking, digital signaturetechnology to protect digital media files while uploading, downloading and using a fullrange of processes such as tracking and monitoring protection against improper use ofdigital media files, protecting the legitimate interests of the copyright side inviolable.With the rapid development of the Internet, distribution of digital media files hasbecome very easy and copyright protection of digital media files has become increasinglydifficult. The main problem faced by digital copyright protection are: dependentanti-counterfeiting packaging and various security labels for digital copyright protectionmethod for copy, piracy, illegal downloading dissemination has been completelyineffective; traditional packaging, such as anti-counterfeiting technology can not fightagainst piracy infringement and have no function of effective traceability forensicstechnical support; otherwise, current digital rights management systems are generallymore cumbersome, because of strict copyright protection of digital media files, some ofthe legitimate interests of the users are often not protected.To solve these problems, firstlyanalyze digital rights management system, using reasonable encryption technology toencrypt digital media files to ensure secure transmission of digital media files on theInternet, protect copyright of digital media files; Secondly, in order to achieve function ofcombating piracy, providing effective traceability, use appropriate digital watermarkingtechnology to embed copyright information and the user characteristics into digital mediafiles, provide technical support for the public security agencies to fight piracy; Finally,to simplify the the operations of digital rights management systems, and focus on userexperience in digital media files while copyright protection, effectively protect theinterests of legitimate users.On the basis of digital rights management system, this thesis design andimplementation of digital rights management encryption system with a trackingtraceability function on the use of encryption and digital watermarking technology, thesystem can effectively manage the copyright of digital media files.
