Research And Realization Of Integrated Management Of Copyright Assets Based On DRM

In the Internet-based information society, the new copyright industry,which focuses on digital products, network media, literature and art,computer software and other industries, has developed rapidly and has a strong scale and strength. However, copyright assets can be easily copied,modified and disseminated in the process of uploading, storing, trading,etc., thus making the copyright assets illegally infringed on the patent rights, and bring economic losses to the rights holders of copyright assets.Copyright transactions in the course of the user's privacy can easily be leaked, user privacy once the leak will give users incalculable losses.Aiming at the digital easily copied and distributed illegally and copyright trading when user privacy is easy to leak problem, put forward to protect the copyright assets model, this model can protect digital content from illegal copying and dissemination, proposes a user privacy protection method of transaction user authentication based on two-way,the method can guarantee the copyright purchase user's personal privacy is not compromised.The main contents of this paper are as follows:(1) A comprehensive management model of copyright assets based on DRM was proposed. The model is mainly composed of five parts,which are the copyright assets encryption system, the property right distribution center, the key management system, the transmission system of the copyright and the decryption system of the copyright assets. The encryption function of copyright assets is encrypted by AES encryption technology, which ensures that the copyright assets are not illegally copied and spread, and the key management system uses the technology of digital watermarking to authenticate users.(2) A user privacy protection method based on bidirectional identity authentication of transaction users was proposed. This protocol is used to solve the problem of privacy disclosure when the copyright asset is transacted. The protocol stipulates that the mutual information can be viewed only after the bidirectional authentication of the transaction user.(3) An integrated management system of copyright assets based on DRM was designed and implemented.Users can make copyright registration in the system, you can also view the copyright asset statistics.At last, the function and performance of the system are evaluated, and the results show that the proposed method has some efficiency.The copyright protection model proposed in this paper has certain value and reference value to the research of the copyright asset management and the copyright protection technology.
