Multimedia Privacy, Security, and Protection within the Blockchain: A Review

Abstract

The fact that wireless and wired sensor and actuator networks have different levels of security is a big challenge when it comes to allowing multimedia applications in the internet of things (IoT). In this work, we create a brand-new, effective security architecture that is both blockchain-based and multimedia-based to support diverse multimedia applications in the IoT. There are several challenges when transferring a file including multimedia data across wireless Internet of Things network peers. Their centralized structure, which increases the risk of security and reachability of users, is one of the key issues. One approach might be simply converting the system to a decentralised network by storing these data on the blockchain network. But it could compromise privacy, longer response time, low latency, and scalability concerns to address users’ low reachability and security problems. Most audiovisual content shared in open spaces (such as wireless networks) runs the danger of being unlawfully duplicated and disseminated with little to no effort, which might have substantial repercussions, including privacy violations and brand damage. It is crucial that an IoT system appropriately secures and protects users’ multimedia data and right to privacy. Unauthorized access to internet of things devices or applications is just one of the unfavorable outcomes of a breach in multimedia data security.
