摘要： 基于电子病历文档的半结构化特性，构建XML电子病历文档。针对原有多重签名计算开销大以及如何使得分解出的子文档具有意义等问题，在Wu等人的算法基础上，对多重签名算法作了改进，优化签名规则，解决签名效率问题，并对其作评估分析。结合XML电子病历文档的特点，构建医疗关键词索引库，使得分解出的病历子文档具有意义。基于XML签名规范，实现该多重签名方案，具有一定的可扩展性。
关键词: XML, 电子病历, 子文档, 多重签名
Abstract: Based on the semi-structured characters of electronic medical record document, the article constructs the XML electronic medical record document. For a large calculation of the original multi-signature, and how to make meaningful subdocuments, on the basis of the Wu’signature algorithm, the article improves the multi-signature algorithm, by optimizing the signature rules. It solves problem of the signature efficiency and evaluates the multisignature. Based on the structure features of XML electronic medical record, the article constructs the medical keywords index database which makes a meaningful decomposition of the subdocument. Based on XML-signature specification, the article realizes the new multi-signature scheme, and the expansibility can be obtained to some extent.
Key words: eXtensible Markup Language, electronic medical record, subdocument, multi-signature
