PROBLEM TO BE SOLVED: To provide a system for integrating a plurality of pieces of information and for performing analysis with high accuracy.SOLUTION: A multiple information analyzing system includes: a plurality of information providing systems each having analyzed information including confidential information; and a convergence system that receives the analyzed information provided from each of the plurality of information providing systems and makes the plurality of pieces of analyzed information available as a target of analysis processing in accordance with the confidential information. The a plurality of information providing systems perform commutative encryption of the confidential information included in each of the analyzed information by an individual encryption key included in the plurality of information providing systems, and transmit commutative encryption analyzed information including commutative encryption confidential information of which commutative encryption is performed by the plurality of information providing systems, to the convergence system. |
