ABSTRACT:
In an information processing apparatus, a first communication unit receives encrypted data from a portable terminal device when the portable terminal device is within a first communication range, a second communication unit receives decryption information from the portable terminal device when the portable terminal device is within a second communication range shorter than the first communication range, and a decryption unit decrypts the encrypted data with the decryption information.
