<P>PROBLEM TO BE SOLVED: To enhance a degree of freedom at the time of communication. <P>SOLUTION: This authentication system 1 is constituted so as to detect tissue data D5 and walking data D7 as biological identification data of a pattern peculiar to a user on the basis of a walking quasi-electrostatic field HSE, which is formed in the vicinity of the user during the walking motion of the user, which is an essential motion for the passage through an entrance and exit passage part 4 (Fig. 6), from a detection electrode 52 through an FET 11 and data high in identification properties peculiar to the user can be obtained without controlling user's motion and applying special processing such as encoding or the like. As a result, the degree of freedom at the time of communication can be enhanced. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
