Abstract
Spoofing is prevented in an authentication technique using a portable terminal and the like. A portable telephone includes an authentication unit for performing personal authentication of the user, a moving distance calculating unit for calculating a linear moving distance the portable telephone has moved from a position of the portable telephone at the time the authentication unit succeeds in the personal authentication of the user; and a post-authentication communication control unit for disabling the settlement process communication if the linear moving distance calculated by the moving distance calculating unit exceeds a predetermined distance.
Claims4
A user equipment for performing post-authentication communication with communication equipment after succeeding in personal authentication of the user;
- the user equipment comprising:
- an authentication unit for performing the personal authentication of the user;
- a moving distance calculating unit for calculating a linear moving distance of the user equipment during a predetermined interval;
- a post-authentication communication unit for functioning to perform an electronic money settlement process communication with the communication equipment;
- a post-authentication communication control unit for locking and unlocking the function of the post-authentication communication,
- wherein the post-authentication communication control unit:
- unlocks the function of the post-authentication communication unit after authentication of the user succeeds;
- commands the moving distance calculating unit to start calculating the linear moving distance of the user unit;
- starts receiving, at the predetermined interval, an integrated value of the linear moving distances of the user each of which is calculated by the moving distance calculating unit, wherein the integrated value is obtained by accumulating a plurality of scalar values;
- judges, at the predetermined intervals, whether the integrated value of the received distances exceeds a predetermined reference value;
- and
- locks the function of the post-authentication communication unit if the integrated value of the received distances exceeds the predetermined reference value, and
- wherein the post authentication communication unit is allowed to initiate the settlement process communication when the calculated linear moving distance does not exceed the predetermined reference integrated value, and the user places the user equipment over the communication equipment.
An authentication method in an authentication system, including a user equipment and a communication equipment, for performing a post-authentication communication between the user equipment and the communication equipment after succeeding in personal authentication of the user of the user equipment;
- the method comprising the steps of:
- authentication of performing personal authentication of the user;
- moving distance calculation of calculating a linear moving distance of the user equipment during a predetermined interval;
- and
- post-authentication communication control of:
- approving the post-authentication communication after authentication of the user succeeds;
- starting reception, at the predetermined intervals, of an integrated value of the linear moving distances each of which is calculated in the moving distance calculation, wherein the integrated value is obtained by accumulating a plurality of scalar values;
- judging whether an integrated value of the received distances exceeds a predetermined reference value at the predetermined intervals;
- and
- prohibiting the post-authentication communication if the integrated value of the received distances exceeds the predetermined reference value, wherein the post-authentication communication is an electronic money settlement process communication.
