<p><P>PROBLEM TO BE SOLVED: To provide an information retrieval system which secures confidentiality of a retrieval key while preventing the retrieval key from being identified by an information retrieval device, even in distributed processing using a plurality of information retrieval devices, and to provide an information retrieval device, an information retrieval terminal, an information retrieval method, and a program. <P>SOLUTION: The information retrieval system 100 includes an information retrieval device 110 and an information retrieval terminal 130. The information retrieval device 110 includes: a data storage unit 121; a retrieval area data receiving unit; a retrieval result data extraction unit; a corresponding data generation unit; and a corresponding data transmitting unit. The information retrieval terminal 130 includes a retrieval key input receiving unit; a retrieval key storage unit; a retrieval area data generation unit; a retrieval area data transmitting unit; a corresponding data receiving unit; a retrieval result data extraction unit; and a retrieval result information output unit which outputs retrieval result data extracted by the retrieval result data extraction unit as retrieval result information for a retrieval key received by the retrieval key input receiving unit. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
