| description | In a confidential information processing server, when a processing query execution unit receives a processing request, a TEE trusted part processing unit generates a confidential extraction query for extracting data that matches with a condition of a processing target in the processing request by confidential extraction based on the processing request and an encryption key that can be used only in a TEE trusted part, the confidential extraction processing unit instructs execution of the confidential extraction query so as to extract encrypted data of the processing target while the data is kept encrypted from an encryption DB unit, the TEE trusted part processing unit decrypts the encrypted data of the processing target extracted by the confidential extraction processing unit with an encryption key, and executes data processing requested by the processing request, and a processing query execution unit returns an execution result of the data processing to a transmission source of the processing request. |
