A wireless battery-powered fingerprint identification system for ubiquitous user authentication

This paper descrihes a fingerprint identjfication .system. The s.v.7tem con,sist.s of an identification module. which identifies the user bv fingerprint, a host. and .service-providing eyiriprnent that offers servims to tlie user. Users carr?; their, o w identification mod& and the module transmits the ideritification result to the host. The host activates the service-providing eynipment accordirig to this result and deactivates the equipment when it recognizes that the iiser has left. The .sv.vtem provides continnoits user airthentication. which certi/ie.s not on!v the presence hut also the ahsence of the genuine user. Protoype systems were fahricated with a fingerprint identification LSI (FIL) that sen.se.7 and verjfies fingerprints at low power withoitt any processor chips. The ,FIL makes possible a small hatter?;. powered module, and the experimental results con/irm tlie .systems can authenticate users continuou.s!v. The proposed sy.stem achieves uhiquitous user authentication in which the itsel’ cun he authenticated anytime anywhere and offered services .secureiv.
