Location-Based Access Control (LBAC) techniques allow taking users' physical location into account when determining their access privileges. This paper presents an approach to LBAC aimed at integrating location-based conditions along with a generic access control model, so that a requestor can be granted or denied access by checking her location as well as her credentials. The LBAC model includes a novel way of taking into account the limitations of the technology used to ascertain the location of the requester. Namely, the authors describe how location verification can be encapsulated as a service, representing location technologies underlying it in terms of two semantically uniform Service Level Agreement (SLA) parameters called confidence and timeout.
