Abstract: Location-based applications (e.g., foursquare, Groupon) rely on each client's assertion of his or her location (e.g., uploaded GPS coordinates). Yet these service providers seek methods to authenticate the location of clients to enhance targeted service delivery and support their advertisers. We propose an intelligent infrastructure-based solution that provides spontaneous, transaction-oriented, collusion-resistant mobile device location authentication to a remote party via an integrated 802.11x wireless access point and 3G femtocell access system.
