基于联盟链的安全可信电子病历智能合约设计
Design of Secure and Trusted Electronic Medical Record Intelligent Contract Based on Alliance Chain

随着医院信息化的发展，越来越多的医院开始着手重点建设智能医疗化电子病历系统，但是，在电子病历等医疗信息数据的存储、访问与管理方面，传统的医疗系统会存在很多问题。区块链技术中的联盟链具有部分去中心化、可控性较强、数据不会默认公开和交易速度很快等特性，能够保护医疗信息数据安全可信同时又能够实现共享。本文针对传统医疗系统在电子病历信息数据方面的痛点，引用联盟链在数据存储中安全可信的特性，提出了一种合理的基于联盟链的安全可信电子病历智能合约设计方法。这种新型的设计方法可以很好的解决目前医疗行业在信息化过程中遇到的数据安全可信与共享方面的难题。
With the development of hospital informatization, more and more hospitals begin to focus on the construction of intelligent medical electronic medical record system. However, there are many problems in the storage, access and management of medical information data, such as electronic medical record. The alliance chain in blockchain technology has some characteristics, such as partial decentralization, strong controllability, no default disclosure of data and fast transaction speed, which can protect the security and credibility of medical information data and realize sharing at the same time. Aiming at the pain point of traditional medical system in electronic medical record in-formation data, this paper introduces the security and credibility of alliance chain in data storage, and proposes a reasonable design method of secure and trusted electronic medical record intelligent contract based on alliance chain. This new design method can well solve the problems of data security, credibility and sharing encountered by the medical industry in the process of informatization.
