基于时间约束的隐私保护数据查询方法研究
Research on Privacy Preserving Data Query Method Based on Time-constrained
摘要
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.关键词
