摘要:
电子医疗记录(EMR)是高度敏感且非常重要的信息记录,医疗记录的共享对患者的准确调治、医疗的发展等方面具有重大意义。 由于各医疗机构的电子医疗记录系统存在数据安全得不到保证、权限验证周期长等问题,造成电子医疗记录不能在安全高效率的环境下共享。 因此,对区块链主要原理和关键技术进行了研究,并基于区块链去中心化、不可篡改、开源透明、可编程等特点,设计了加入改进的拜占庭容错系统共识机制的电子医疗记录共享模型,能够为数据安全和隐私存储提供保障。 文中对电子医疗记录模型进行分析评价,保证安全的同时可以减少医学数据共享的周转时间,从而提高效率。 最后探讨了基于区块链技术的医疗共享系统目前有待解决的问题和局性。
Abstract:
The electronic medical records (EMR) are highly sensitive and very important information records. The sharing of EMR is of great significance for accurate treatment of patients and the development of medical treatment. Electronic medical records of medical institutions cannot be shared in a safe and efficient environment due to problems such as lack of data security guarantee and long period of authority verification. Therefore, the main principle and key technology of Blockchain are studied, and based on the characteristics ofBlockchain decentralization,non-tamper,open source transparency and programmable,an ESR sharing model with improved Byzantine fault tolerant system consensus mechanism is designed,which can provide protection for data security and privacy storage. We analyze and evaluate the electronic medical record model to ensure the safety and reduce the turnover time of medical data sharing,thus improvingthe efficiency. Finally,the problems and limitations of medical sharing system based on Blockchain technology are discussed.
