基于医院信息系统和Oracle9i数据库的网络化口腔电子病历安全体系的研究

Study of stomatological electronic medical record network security system based on hospital information system and Oracle9i database

目的探讨网络化口腔电子病历安全体系的实现方式。方法在Windows 2000/XP平台上,结合基于HL7标准的XML语言、Oracle9i数据库构建多层分布式的网络化口腔电子病历系统,通过用户名和密码MD5技术加密、角色分配、分级权限、痕迹保留、审计追踪、DES数据加密、数据备份、实时监控、网络管理、服务器双机热备份等方法构建网络化口腔电子病历系统的安全体系。结果本研究构建了基于局域网的网络化口腔电子病历系统安全体系,可确保电子病历信息录入、修改、存储和传输的安全。结论该网络化口腔专科电子病历符合口腔专科医院信息系统安全管理的需要,有助于推动口腔专科医院的信息化管理建设。

Objective To develop a security system for stomatologieal electronic medical reeord network system. Methods On the basis of Windows 2000/XP operation system, XML based on HL7, oracle9i database, client/server architecture, the stomatological electronic medical record network security system was built up by usernames and passwords encipherment with MD5 technique, roll allocation, rank management and right constraint, trail reservation, auditment and tracing, DES encipherment, data backup, real-time monitoring, network security control and double servers warm-back-up. Results The stomatologieal electronic medical record network security system based on local-area network was success- fully built up, and was assured in imput, revision, preservation and transportion. Conclusion This system met the security management needs for stomotologieal hospital information system and improved the information management in stomotological hospitals.
