AN "ALL-IN-ONE" MOBILE DRM SYSTEM DESIGN

Intellectual property violation events have caused enterprises to respect digital content protection. However, valuable digital content without effective management mechanisms will make the content vulnerable to unauthorized copying, modification. and re-distribution., causing revenue losses to service providers In this paper, we propose an efficient rights management protocol for mobile devices We integrate the role of the Mobile Network Services Provider (MNSP) and Content Provider into our scheme to provide an "All-In-One" mobile DRM system. The proposed scheme is superior to the Microsoft, and OMA DRM system in privacy protection Our scheme extends the non-repudiation service in a OMA-based DRM version and also proposes a novel DRM content formal (DCF) structure that integrates the existing applications To overcome the computing resource weakness problem m. mobile devices, we also integrate a password mechanism and a one-way hash function such that the security, individualization, flexibility, efficiency and practicability issues will be assured in this way. the mobile user can conduct a transaction. anywhere wild anytime and the digital content provider will not suffer from unauthorized mobile users accessing digital content.
