摘要:
很多学者和机构在研究隐私保护的分布数据挖掘方法时，通过挖掘全局数据以保护各站点数据的隐私和安全。但是这些方法假设数据集成已经完成，隐私保护数据挖掘处理的是集成问题解决后的知识获取问题。因此，在隐私保护数据处理之前的数据集成中，如何保护来源数据的隐私信息，是一个必须解决的问题。文章在考虑数据的时效性因素下，提出了一种采用Shamir's秘密共享方法的时间约束隐私保护数据查询方法，重点介绍了时间约束下隐私保护数据集成与共享中的聚集操作方法。实验结果表明文中方法可以有效提高隐私保护数据查询的效率，大大降低隐私保护数据查询的响应时间
Abstract:
Many scholars and institutions protect the site data privacy and security through the global data mining in the research of distrib-uted data privacy protection. But these methods assume that the data integration has been completed,processing of privacy preserving data mining is the problem of obtaining knowledge after the integrated problem solving. Therefore,before the privacy preserving data process-ing in data integration,how to protect the privacy information of data sources is a problem that must be solved. Propose a privacy-preser-ving data sharing method applied the Shamir's secret sharing method with time-constrained. Some basic operations utilized this method for the privacy preserving and data integration and sharing,such as intersection,join and aggregation,are emphatically illustrated. The ex-perimental results demonstrate that this method is effective and greatly improves the efficiency and significantly reduce response time of the privacy-preserving data query
