摘要： A method and system for publication control of digital content for validating the rights information registered by a plurality of separate content providers. When receiving a digital content publication application from a content publication unit, a publication control unit queries whether rights information corresponding to the digital content to be published is stored in a rights publication unit, and if stored, allows the publication of the digital content and of a download address thereof. By messaging rights information in this centralized manner, it may be ensured that a content buyer can efficiently obtain the rights object distributed after the digital content is published.
