Abstract
An aspect of the present invention is provided with a sensitive data protection code generating unit which generates a sensitive data protection code of a predetermined data length, a symmetric encryption key generating unit which generates a symmetric encryption key by using a key derivation function that takes, as input, the sensitive data protection code, a sensitive data encrypting unit which encrypts sensitive data by using the symmetric encryption key, a sensitive data protection code encrypting unit which encrypts the sensitive data protection code by using a public key provided from an sensitive data access support terminal, and a deleting unit which deletes the symmetric encryption key and the sensitive data after the encryption of the sensitive data, and deletes the sensitive data protection code after the encryption of the sensitive data protection code.
