Patent ID: 8068607

Claim:
An information processing system comprising: a portable terminal device; and an information processing apparatus, the portable terminal device including a first communication unit that establishes wireless communication with the information processing apparatus when the information processing apparatus is present within a first communication range, and that transmits encrypted data to the information processing apparatus; and a second communication unit that establishes communication with the information processing apparatus when the information processing apparatus is present within a second communication range shorter than the first communication range, and that transmits decryption information used for decrypting the encrypted data to the information processing apparatus, and the information processing apparatus including a third communication unit that establishes wireless communication with the portable terminal device based on a first communication protocol same as that of the first communication unit when the portable terminal device is present within the first communication range, and that receives the encrypted data from the portable terminal device; a fourth communication unit that establishes communication with the portable terminal device based on a second communication protocol same as that of the second communication unit when the portable terminal device is present within the second communication range, and that receives the decryption information from the portable terminal device; and a decryption unit that decrypts the encrypted data received by the third communication unit with the decryption information received by the fourth communication unit.
