Authentication system
First Claim
1. An authentication system comprising a sending device and a receiving device for sending and receiving information via a quasi-electrostatic field, characterized in that:
- the sending device comprises;
living organism information generation means for generating living organism information specific to a human body; and
electrification induction means for electrifying the human body by generating a quasi-electrostatic field modulated according to the living organism information; and
the receiving device comprises;
demodulation means for demodulating the living organism information based on change in the electrification condition of the human body; and
identification means for identifying the human body based on the living organism information.

Abstract
The present invention enables the degree of freedom in communication to be enhanced. According to the present invention, in an authentication system 1, during a walking motion of a user which is essentially required for the user to pass through an entrance/exit passage portion 4 (FIG. 6), tissue information D5 and walking information D7 as living organism identification information, a pattern specific to a user, is detected from an detection electrode 52 via an FET 11, based on a walking quasi-electrostatic field HSE formed in the neighborhood of the user. Thereby, information with high identifiability specific to the user can be obtained without controlling movements of the user and without performing special processing such as encryption. Thus, the degree of freedom in communication can be enhanced.
