【Abstract】Advancement in Internet technology is providing the exponential growth to the multimedia industry, which handles digital content broadcast and distribution over the internet. It also faces several series of challenges such as the transgression of copyrights, multimedia content security, efficient communication, user privacy, secure and authorized communication, etc. In general, centralize authority works to address security and privacy. Thus, the existing mechanism will not work if the decentralized and heterogeneous system occurs. To attain an effective solution for content distribution, blockchain-based content distribution framework is provided to ensure authenticated and efficient access. The proposed protocol gives the method of blockchain-based access control with user revocation, which provides an alternative solution to handle the decentralization and revocation issues. This multimedia content distribution framework ensures security against malicious users. The proposed scheme security is proved in the widely recognized random oracle model. The comparative analysis of the proposed scheme with relevant schemes shows the enhancement in term of efficiency.
