発明の名称 (英語) ENCRYPTED DATA PROCESSING SYSTEM AND PROGRAM NEW
発明の概要(英語) Provided is an encryption data processing system, comprising: an encryption device comprising an encryption unit for encrypting first information on the basis of a first encryption key and transmitting encrypted information for registration to a server and for encrypting second information on the basis of a second encryption key and transmitting encrypted information to be collated to the server, the server comprising a collation unit for collating the encrypted information to collate the encrypted information for registration with the encrypted information to be collated using an encryption collation function and transmitting a collation result to the encryption device; the encryption device further comprising a collation result decoding unit for determining the degree of matching between the first information and the second information on the basis of a decoding function for decoding the collation result using the first encryption key and the second encryption key.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventionally, the encrypted information has been developed is a technique for processing.
For example, the database server and a client terminal for encrypting information during communication, one using the encryption key 2 encrypted to improve security is a technique (Japanese Patent Laid-Open Patent Publication 2007-318518).
In addition, the double encrypted registered data and generates the encrypted data is registered, is a technology for preventing illegal alteration (Japanese Patent Laid-Open Patent Publication 2015-192446).
In addition, the collation biometrics characteristic data and comparing the registered biometric feature data, and collation, if a predetermined matching condition is satisfied, the password, transmitted to the control apparatus from the portable electronic apparatus is a technique (re-published Japanese Patent Application 2001-42938).
In addition, the use of encryption techniques such as a relational database, and the ciphertext, and the ciphertext by comparing the approximate registration, user authentication is a technology (JP-2015-225343 publication, JP-2017-21330 Publication, and Japanese Patent Laid-Open Publication 2017-21331).
