Research And Application Of The Digital Content Transaction And Distribution Platform Based On DRM

Combined with the current situation in the field of digital publishing,“Research and Application of the Digital Content Transaction and DistributionPlatform Based on DRM” focused on solving the key thorny problem in the digitalcontent transaction and distribution process. Based on the relevant key technologyresearch, eventual establishs a copyright protection of digital content distributionplatform process. An efficient and flexible Digital Content Transaction andDistribution Platform Based on DRM needs to be studied and designed in thisthesis. The main works are as follows:(1) The DRM technology are studied and analyzed. The main researchachievements about domestic and foreign on DRM as well as their problems andlimitations are described.(2) The DRM technology is studied in detail, of which the rights expressionlanguage is explored specially. The cryptography used in DRM technology isdescribed, and the XML technology and related standards are studied.(3) Currently, Digital rights management can not effectively implementsegment rights expression and dynamic segment authority, this paper demonstrateda model based sectional control, this model carried out segment rights expressionand dynamic segment authority. The process of digital content super-distribution,distribution and secondary distribution are described. The correlation analysis hasshowed the extended model is secure, and easy implementation.The digital content transaction and distribution platform based on DRM iscarried out by this dissertation, which provides solutions for the trading anddistribution of digital content, ensures the dissemination and legal use of digitalcontent throughout the life cycle, and balances the interests and needs of variousroles in a digital content value chain. This platform has been put into practical usein the Anhui Education Press.
