  • Publication number: 20240169087
    Abstract: A searcher terminal acquires condition data. The searcher terminal extracts a feature from the condition data. The searcher terminal generates a flag from the feature of the condition data. The searcher terminal encrypts the flag of the condition data. The searcher terminal encrypts the feature of the condition data. The secure search apparatus acquires an intermediate search result indicating a ciphertext of a target feature corresponding to a target flag matching the condition flag while keeping the target flag and the condition flag secret. The secure search apparatus acquires a search result indicating a ciphertext of target data corresponding to a target feature similar to the condition feature among target features indicated by the intermediate search result while keeping the target feature and the condition feature secret. The secure search apparatus transmits the search result to an encryption apparatus and the searcher terminal.
