| Digital Rights Management (DRM) is the tool that protects and manages the intellectual property of digital content during producing, spreading, selling and using. Its target is to make use of technique means to suppress pirating, to protect the intellectual property of digital product, to ensure the outlet of the market sale expedite of digital products, and to guarantee the benefits of authors, publishers and the legal usage right of the customers.Based on collecting and analyzing literatures internal and overseas about DRM, the paper studies the technique system, function structure and information structure, main technical theory, and the system model of DRM. The paper also probes into the application of DRM on e-book copyright management. Combining with elliptic curve digital signature, the paper forwards an e-book attestation arithmetic which is based on hardware fingerprint. And then the paper takes the advantage of mobile agent technique and forwards a reformative DRM system model.With the quick development of network, various forms of e-book publication, such as bookstore, appear on internet. In order to suppress these actions, such as pirating, illegal copying and spreading, it is important to protect copyright of e-books. So, a simple e-book on-line distribution system, which is based on DRM, is finally designed and achieved in this paper. The system uses machine fingerprint to achieve customer identity attestation and license usefulness verification, and thus achieving copyright protection of e-books on-line and off-line efficiently. |
