Abstract: The advent of distributed applications and cloud computing is posing considerable difficulties in securing the data. Centralized data management systems are prone to failures, breaches of security, and lack of transparency. In this research work, we propose an effective model that provides secure data management using blockchain technology by adopting decentralized storage, smart contracts, and cryptography. In the proposed model, we use the InterPlanetary File System (IPFS) for decentralized storage of data, Ethereum blockchain for managing the metadata of the data immutably, and role-based access control through smart contracts. Our performance evaluation shows that our model provides a data availability rate of 99% when 50% chunk is lost. Our proposed framework gives an improvement in data processing time by 2.54 times and 18.3% improvement in data integrity verification over previous methods.
