[Abstract]:Digital copyright protection is a hot issue in the field of copyright protection, which is related to the protection of intellectual property. It has important theoretical research value and extensive application background. Digital rights protection mainly through the digital rights management system, using encryption, digital watermarking, digital signature and other technologies to upload, download, use of digital media files to carry out omni-directional follow-up and protection. Prevent the improper use of digital media documents and protect the legitimate interests of copyright parties. With the rapid development of Internet, the circulation of digital media files becomes very easy, and the copyright protection of digital media files becomes more and more difficult. The main problems facing digital copyright protection are: relying on anti-counterfeiting packaging and various kinds of anti-counterfeiting labels for digital copyright protection, copyright infringement and piracy, such as copy, illegal download and transmission, have been completely invalidated; Traditional packaging anti-counterfeiting and other anti-infringement technology can not provide effective technical support for public security organs to crack down on piracy infringement. In addition, the current digital rights management system is generally more cumbersome, sometimes in order to strictly protect the copyright of digital media files, the rights and interests of some legitimate users are often not protected. In view of the above problems, we first analyze the digital rights encryption management system, and use reasonable encryption technology to encrypt the digital media files to ensure the secure transmission of the digital media files in the Internet. To protect the contents of digital media files; Secondly, in order to combat piracy and provide effective tracing to the source, the corresponding digital watermarking technology is used to embed copyright, user characteristics and other information into digital media files to provide technical support for public security organs to combat piracy infringement; Finally, simplify the use of digital rights encryption management system, pay attention to user operation and experience, while protecting the copyright of digital media files, effectively protect the interests of legitimate users. Based on the basic principle of digital rights encryption management system, this paper designs and implements a digital rights encryption management system with the function of tracing and tracing the source by using encryption and digital watermarking techniques. The experimental results show that the system can effectively manage the copyright of digital media files.
