Abstract
A short video copyright storage method based on blockchain and expression identification, wherein first, the video key information of face short videos is calculated by an method of convolution neural network based on visual priority rules, and second the key information is stored in an alliance blockchain in the form of log files to complete the digital copyright storage of short videos. The method includes: authenticating alliance chain member nodes, which can store the short video digital copyright and perform other operations after being authenticated; extracting key information of face short videos; calculating the feature vector of key information through a deep learning method; enhancing the calculation of the feature vector to improve the efficiency of certificate storage; generating JSON file of digital copyright identification tag value of face short video.
