Intelligent Mediator-based Enhanced Smart Contract for Privacy Protection

Abstract

With the development of ICT technology, users are actively participated in content creation and sharing. Service providers have provided more diverse and extensive information services. With the recent evolution to a customized service, the demand for the use of personal information is increasing. However, it affects the efficiency and convenience of service provision, as social problems and security threats such as personal information leakage, human trafficking, and misuse increase. In this article, we proposed an intelligent mediator-based enhanced smart contract for privacy protection. The proposed approach performs the tasks, which are mediation transactions, authorization, and transaction record management, with blockchain-based personal information management. Then it is possible to prevent misuse of personal information and to support rational decision-making on the transparency of information and the use of personal information by autonomously performing personal information management.
