| titleOfInvention | Server device, retrieval system, terminal device, and retrieval method |
| abstract | The present application provides a server device, a retrieval system, a terminal device and a retrieval method. In the server device (301), a data storage unit (303) stores a plurality of encrypted data. An index storage unit (304) stores, as an index I, a data structure for searching using a function H that outputs a unique numerical value for an input keyword, the data structure having a plurality of storage areas corresponding to the numerical values output from the function H one-to-one, For the plurality of keywords corresponding to the plaintext data, in the storage area corresponding to the numerical value output from the function H by inputting each keyword, the data obtained by encrypting the plaintext data corresponding to each keyword, that is, the identifier of the encrypted data is stored symbol. The retrieval unit (305) inputs an arbitrary keyword among a plurality of keywords to the function H, specifies the storage area corresponding to the value output from the function H based on the index I, and obtains from the data storage unit (303) the storage area corresponding to the specified storage area. The encrypted data corresponding to the stored identifier. |
