Biometric Authentication in Broadband Networks for Location-Based Services

Abstract

Broadband communication networks have begun to spread rapidly over fixed networks, with wireless networks following at close distance. The excess capacity allows the offering of broadband services at competitive rates. Location-based services (LBS) over wireless broadband networks are becoming mainstream in an emerging ambient intelligence society. For LBS over broadband and, in particular, peer-to-peer networks, such as ad hoc networks, unambiguous user authentication is of paramount importance to user trust and safety, thus ultimately to the success of such service. Biometric authentication is an approach to providing irrefutable identity verification of a user, thus providing the highest level of security. This chapter addresses some of the issues associated with the use of biometric ID for user and apparatus authentication over broadband wireless networks (e.g., GPRS, UMTS, WiFi, LANs) and narrow band local networks (e.g., bluetooth, Zigbee, PANs, BANs).
