Many scholars and institutions protect the site data privacy and security through the global data mining in the research of distributed 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 processing in data integration,how to protect the privacy information of data sources is a problem that must be solved.Propose a privacy-preserving 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 experimental results demonstrate that this method is effective and greatly improves the efficiency and significantly reduce response time of the privacy-preserving data query.
