Blockchain-based distributed application for multimedia system using Hyperledger Fabric

Over the past few years, blockchain technology has acquired good faith as a modern, secure distributed network in the form of a ledger to conduct and store records of transactions. Blockchain is an evolving technological innovation that can offer solutions to real-world problems of various domains such as cloud computing, the Internet of Things, supply chain, and multimedia. In multimedia, there is an increased requirement for security due to various threats, including replicating digital data without any information loss and manipulating the same without any detection. Moreover, the security of personal multimedia systems is perceived as one of the fundamental human rights concerns. Therefore, this paper proposed a blockchain-based distributed application to secure personal multimedia data such as images, text, videos, etc. The proposed work maintains personal multimedia data's security, privacy, and integrity to meet multimedia security requirements and address the above issues. The blockchain architecture is developed on Hyperledger Fabric, a permissioned blockchain structure using Hyperledger Composer, and stores multimedia data by utilizing SWARM decentralized storage system. The proposed architecture provides a cross-platform, low-cost, and energy-efficient blockchain prototype to manage and secure personal multimedia data. Many experimental tests are conducted to evaluate the performance of the proposed work based on various parameters such as transaction latency, asset latency, throughput, power consumption, upload, and download time for multimedia data. Finally, the proposed work's robustness, feasibility, and reliability are proved by comparing it with the existing works. Results and discussion show that the proposed scheme is more efficient than the existing schemes.
