This paper proposes a digital copyright certification system based on network which extracts the feature information with DCT coefficients and then stores them in the network servers. This can avoid completely distorting images, however, the cost of computing and network transmission will be increased during checking copyright information. To enhance the computation speed and efficiency of extracting and authenticating feature information, the system optimizes the process of extracting and matching with MapReduce model. After actual sample testing, the system has higher copyright recognizing accuracy and scouting speed, as well as outstanding effect on digital right protection.
