Abstract

With networking, big data and rapid development and wide application of 5G networks, traditional network architecture cannot handle massive amounts of media data generated by a large number of mobile or PC devices. In recent years, events on multimedia and data copyright violations of a substantial increase, data security and privacy protection of many original multimedia users is suffering an unprecedented challenge. On the other hand, due to the center and the invariance of the block chain, block chain has become a promising multimedia security technology. Blockchain technology provides a common, digitized and distributed books, P2P network composed of all peer nodes interconnected to each other, all participating nodes are equal, collaborative service, compared to traditional architecture under a single central point, can greatly reduce the risk of single point of failure. In this paper, based access scheme in combination with the secure multi-computing protocol blockchain system, the user needs to conduct the authentication system under the multi-computing in order to receive the data, greatly enhance the data safety of multimedia in complicated communication sceneries. In addition, the program mentioned in the text and related simulations and proof of security, usability and reliability can be guaranteed.
