Abstract
An apparatus for generating a secret key generates the secret key by using information of a mobile RFID terminal, transmits the generated secret key to an RFID tag attached on an article, and decrypts a unique item identifier of the article encrypted by using the generated secret key after receiving the unique item identifier of the article encrypted by using the secret key from the RFID tag. By this configuration, it is possible to protect user's personal privacy of the mobile RFID terminal in a state where user's intervention is minimized.
