Abstract

When transmitting position/time information calculated by means of a GPS function to a server apparatus, authentication is carried out with the server apparatus. The position/time information may be certified as legitimate measured by a portable apparatus with a GPS reception function employed by a user. When transmitting information related to the position and the time acquired from a portable phone terminal having the GPS function and a network function by means of the GPS function to the server apparatus, authentication is carried out between the portable phone terminal and the server apparatus. The position/time information is transmitted to the server apparatus, only if the server apparatus is authenticated as a legitimate counterpart for connection.

Claims

1. An information terminal apparatus, comprising:

reception means for receiving satellite signals transmitted from artificial satellites comprising a global navigation system;

calculation means for calculating, based on said satellite signals, current-position/current-time information indicating a current position and a current time of said information terminal apparatus, independent of a link between said information terminal apparatus and an information processing apparatus;

authentication means for determining whether said information processing apparatus is a legitimate counterpart for connection with said information terminal apparatus, and for permitting communication means to transmit information data to said information processing apparatus only when said information processing apparatus is authenticated as a legitimate counterpart for the connection;

said communication means for transmitting/receiving said information data to/from said information processing apparatus via a communication network, said transmitted information data including identification information identifying said information terminal apparatus and a user thereof to said information processing apparatus, and a condition that is met based on said current-position/current-time information, said communication means not transmitting said current-position/current-time information to said information processing apparatus;

informing means for informing said user of said identification information;

key generating means for generating an encryption key based on said current-position/current-time information after said information processing apparatus is authenticated as a legitimate counterpart;

encryption means for encrypting said information data transmitted by said communication means to said information processing apparatus; and

decryption means for decrypting said information data received from said information processing apparatus using said key only when said information terminal apparatus meets said condition by being within a predetermined position range, a predetermined time range, or both the predetermined position range and the predetermined time range.
