According to the characteristics of the existing copyright protection system and market demand, a copyright registration and monitoring system based on digital watermarking and fingerprint technology was designed and implemented.Users can register audio, video, image and other types of digital content on our system, in which the only fingerprint is used to replace the original work itself for registration. After the approval, the unique watermark is issued for embedding in the digital content, so that when the infringement is identified, the watermark can be extracted from the suspected infringing works to prove the copyright, and this will break through the difficulty of obtaining evidence and safeguarding rights.The system also is real-time and accurate for copyright monitoring works. It can provide users with instant feedback, including suspected infringement works. Our system combines the advantages of digital watermarking and fingerprint technology in copyright protection, simplifies the copyright registration, makes the infringement identification effective, and makes the copyright monitoring accurate, so as to effectively prevent the occurrence of infringement and piracy, which is conducive to the promotion and popularization of digital works copyright protection.
