提出了计算机化的记录散列编码和链接程序，以允许在流行病学后续行动的框架内链接医疗信息。在提取文件之前，文件使用基于标准散列算法(SHA)函数的单向散列编码进行匿名处理，以尊重有关数据隐私和安全的立法。为避免字典攻击，在SHA编码中添加了两个密钥。一旦匿名，患者信息的链接就可以通过统计模型来完成，同时考虑到几个识别变量。对这一匿名记录链接程序的质量评估显示，特异性为100%，敏感性为95%。(C)1998爱思唯尔爱尔兰科学有限公司。保留所有权利。
A computerised record hash coding and linkage procedure is proposed to allow the chaining of medical information within the framework of epidemiological follow-up. Before their extraction, files are rendered anonymous using a one-way hash coding based on the standard hash algorithm (SHA) function, in order to respect the legislation on data privacy and security. To avoid dictionary attacks, two keys have been added to SHA coding. Once rendered anonymous, the linkage of patient information can be accomplished by means of a statistical model, taking into account several identification variables. Quality assessment of this anonymous record linkage procedure shows a specificity of 100% and a sensitivity of 95%. (C) 1998 Elsevier Science Ireland Ltd. All rights reserved.
