To secure business continuity is indispensable for hospitals to fulfill its social responsibility under disasters. Although to back up the data of the hospital information system (HIS) at multiple remote sites is a key strategy of business continuity plan (BCP), the requirements to treat privacy sensitive data jack up the cost for the backup. The secret sharing is a method to split an original secret message up so that each individual piece is meaningless, but putting sufficient number of pieces together to reveal the original message. The secret sharing method eases us to exchange HIS backups between multiple hospitals. This paper evaluated the feasibility of the commercial secret sharing solution for HIS backup through several simulations. The result shows that the commercial solution is feasible to realize reasonable HIS backup exchange platform when template of contract between participating hospitals is ready.
确保业务连续性对于医院在灾难期间履行社会责任至关重要。虽然在多个远程站点备份医院信息系统（HIS）的数据是业务连续性计划（BCP）的关键策略，但处理隐私敏感数据的要求增加了备份成本。秘密共享是一种将原始秘密消息拆分的方法，这样每个单独的部分都毫无意义，但将足够数量的部分组合在一起就能揭示原始消息。秘密共享方法便于我们在多家医院之间交换HIS备份。本文通过多次模拟评估了用于HIS备份的商业秘密共享解决方案的可行性。结果表明，当参与医院之间的合同模板准备好时，该商业解决方案对于实现合理的HIS备份交换平台是可行的。
