Developing a Transparent Tax Data Access Control System Based on Blockchain

Abstract

Access control systems regulate the access to critical resources and they are vitally important for every organization’s IT infrastructure. Access controls authenticate and authorize individuals to access or deny the information they requested. Access control systems in today mostly provide the ability for centralized authorities, whether governments, service providers or manufacturers, or to gain unauthorized access to users data. The potential of blockchain, distributed ledger technology (DLT) plays an important role because it provides a decentralized and peer-to-peer network system to certain a transparent and secured information storage and transmission. Current DLT systems are now facing some QoS requirements and virtualization for distributed ledger technology (vDLT) can fulfill such requirements with the benefits of virtualization technology. This paper proposes a testnet of transparent tax administration system by using organization based access control (OrBAC), and multichain, a private blockchain platform with the help of vDLT.
