BLOCKCHAIN BASED DATA SHARING

In traditional cloud storage systems, all data is stored in the cloud server, which could lead to major issues including key misuse and privacy data leaking. However, because the traditional cloud storage system depends on centralized storage, a single point of failure could cause the system to fail. With the advancement of blockchain technology, decentralized storage has become more well-known. Decentralized storage can overcome the problem of a single point of failure in typical cloud storage systems while also providing a variety of benefits over centralized storage, including low cost and fast throughput. In this work, focus on data storage and sharing in decentralized storage systems and propose a framework that includes IPFS, an encryption technique, and blockchain technologies. The data holder can distribute secret keys to data users and encrypt shared data location by Blockchain network. In this research contribute to data integrity verification in the blockchain network.
