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.

基于智能中介的增强型隐私保护智能合约

随着ICT技术的发展，用户积极参与内容创作和分享。服务提供商提供了更加多样化和广泛的信息服务。随着最近向定制服务的发展，对使用个人信息的需求正在增加。然而，随着个人信息泄露、人口贩卖、滥用等社会问题和安全威胁的增加，它影响了服务提供的效率和便利性。在本文中，我们提出了一种基于智能中介的增强型智能合约来保护隐私。所提出的方法通过基于区块链的个人信息管理来执行调解交易、授权和交易记录管理等任务。
