Blockchain technology has been expanding in the field of digital rights management. Blockchain has the characteristics of openness and transparency. If the digital copyright is stored in the Blockchain as a whole, it is difficult to protect the privacy of the copyright. At the same time, due to the limitation of the block size, large copyright files are difficult to store. This study proposes a Blockchain video rights management framework based on deep learning. Under the condition of ensuring that the video copyright can be stored in the basic Blockchain, this architecture uses OpenPose to output the 18 key points for the pose of the characters in the character video, extracts the key information of the relevant digital copyright, and finally stores it in the Blockchain, which not only ensures the privacy of the information, but also ensures the efficient storage of the information.
