Smart contract-based access control in file sharing

Abstract

Smart contract is the core of blockchain networks. It eliminates the requirement for third-party services. They are the self- executing contracts that compose rules and terms of transactions that should be agreed upon by every participating node. Smart contracts are executed in a decentralized environment of blockchain. The conditions of an agreement are written in a code that is coded using various programming languages. With more advancement in technology, access control to data has become increasingly difficult. The users need to have access to their assets and resources to complete the job even if the location is remote. We proposed smart contract-based system architecture to implement contract policies to manage access control over the given data. This will help in maintaining data security and integrity and avoid unauthorized attacks.
