摘要
可扩展标志语言在实现信息标准化、信息统一、信息交换和共享上有其独特的技术优势。利用这些优势可以将可扩展的标记语言(extensible markup language,XML)技术运用到电子病历系统中。由于电子病历具有法律效力,因此需要一种机制来确保其安全。点对点的安全机制例如SSL和TLS仅仅能确保数据的完整性与机密性,电子病历系统需要解决的安全问题是对多重签名的不可抵赖性。该文通过介绍签名文档及其元素的XML模式来显示如何确保不可抵赖性。
Electronic medical record（EMR） system is used for storage and transmission in the form of extensible markup language（XML） documents. The structure of XML document is very appropriate description of the contents of the medical documents. According to the characteristics of XML.-based EMR, this system uses XML schema models for developing the structure and content of medical documents,and makes sure the medical documents can be linked smoothly between different hospitals. Furthermore,this system provides encryption and signature components which uses encryption and signature standards followed by W3C. This paper tells how to develop EMR security system,and then analyses some key modules.
