Digital Rights Management Ecosystem: Open Issues and Challenges

Digital rights management ecosystem is a comprehensive copyrighted contents value chain and its measures to counteract copyright infringements, and nowadays there is primarily involved with security-centric policies and mechanisms. Regarding the ecosystem enabling contents acquisition and share scenarios, we highlighted a range of open issues and frontier challenges on hard security and soft computing in the ecosystem, such as the usage control in digital home networks, multi-stakeholder trust and assessment in multimedia social networks, as well as security risk management for digital contents and rights redistribution led by the limited security and uncertain trust, in order to establish a prosperous and healthy digital contents industry.
