Review on Storage Platforms and Access Control Policies in Blockchain

A cloud storage can be construed as a storage with different devices, diverse domains, and services. It is less expensive and more reliable and efficient when compared to local storage. The cloud storage had one of the significant issue of lack of control in transparency over the data stored. The users cannot assert the compensation if their data is compromised or damaged. The provenance of data can be maintained using the blockchain. In this paper, we study the existing access control policies and real time storage frameworks of blockchain used in applications to solve the existing problems of security and the performance parameters.
