Abstract

Provided are a media content licensing method and device based on block chain technology. In the media content licensing method, a block chain node receives a media content licensing request sent by a sending end, wherein the media content licensing request comprises media content identification information and user identification information; and the block chain node returns a temporary license to the sending end according to the media content identification information and the user identification information, wherein the temporary license comprises a decryption key and a temporary licensing time for the media content. The media content licensing method makes it possible to realize a decentralized media content licensing control mechanism by introducing block chain technology.
