Research And Implementation Of E-Book Copyright Protection Technology Based On Windows Phone

After the emergence of digital media, digital copyright protection technology has become an important research content. At present, the mobile network has increasingly occupied an important position in life, and digital reading has become more and more popular. Therefore under the environment of the mobile Internet, e-book copyright technology has been more valued. Windows Phone started late, but has occupied a certain position during the mobile terminals, so the relevant technology of the Windows Phone platform has a relatively wide research space.In the thesis, in order to solve the problem of copyright protection of eBooks based on Windows Phone (WP) platform, the OMA DRM standard features were analyzed; e-book copyright protection system architecture based on mobile Internet was designed; the system based on the WP8platform was implemented and analyzed; the advantages of the system was presented.The main research works are as follow:(1) Proposed the improved copyright protection model MEDRM based on OMA DRM2.0. According to the inadequacies of OMA DRM2.0, the new features were proposed as follow:The legitimate users were allowed to re-request the appropriate file within its competence to the server. It was allowed to re-bind the device within the same region, and the old device which has been eliminated was recorded in the blacklist. The encryption and decryption was segmented. Because the processing capacity of mobile terminal was weak, the encryption and decryption approach took segmented. (2) Proposed and designed the e-book copyright protection architecture based on MEDRM. Based on the MEDRM, designed the architecture of the e-book copyright protection, and then designed the processes within the subsystems.(3) Designed and implemented the copyright protection system based MEDRM. The function of each module processes of the system design was introduced in detail. The process to implement copyright protection was explained; and then the Implementation technologies were introduced.(4) Tested and analyzed the function and performance of the system. Finally, the system was tested and analyzed to verify the safety of new features.In the thesis, the MEDRM was presented. Comparing with OMA DRM2.0, it was more flexible and closer to the demand of user. In addition, the system based on MEDRM combined the features of the Windows Phone platform, which made the client’s data with higher security. The system which was on the bases of protection the e-book copyright’s security, enhanced the user experience, and provided a reference for the application development under " Windows Phone platform.
