Personal authentication system
First Claim
1. A person authentication apparatus having a memory unit, a processing unit and a login function. said apparatus comprising:
- a reader unit for reading radio tag information on a radio tag that is present therearound;
wherein;
said processing unit checks up information from a plurality of radio tags detected by said reader unit with a list concerning radio tag information on personal belongings acquired at the time of login,said list has a weighted coefficient showing an extent of time length at which an RFID tag is mounted for each personal belonging classification,a login state is adapted to be held in the case where an extent of check-up coincidence meets a predetermined reference value, andthe calculation of said extent of check-up coincidence is performed by means of an operation using said weighted coefficient.

Abstract
An apparatus is disclosed for reducing the vexatious complication of personal authentication when using an information technology device or a card. A combination of RFID tags worn by a user is stored when personal authentication is carried out. The RFID tags are detected again In a situation where personal authentication is required. The continuous use of the previous personal authentication is permitted depending on the extent of coincidence between pieces of RFID information thus detected and the combination of stored RFID information, so that further authentication operations can be omitted. In addition, reference is made to a past archive when an RFID list is created. A weighted coefficient is then calculated based on the put-on frequency (put-on archive) in terms of a user'"'"'s single article or a combination of such articles. The utilization of the weighted coefficient provides personal authentication with a high level of reliability.
