Geolocation Policy: A Document Format for Expressing Privacy Preferences
                        for Location Information

Abstract

   This document defines an authorization policy language for
   controlling access to location information.  It extends the Common
   Policy authorization framework to provide location-specific access
   control.  More specifically, this document defines condition elements
   specific to location information in order to restrict access based on
   the current location of the Target.

   Furthermore, this document defines two algorithms for reducing the
   granularity of returned location information.  The first algorithm is
   defined for usage with civic location information while the other one
   applies to geodetic location information.  Both algorithms come with
   limitations, i.e. they provide location obfuscation under certain
   conditions and may therefore not be appropriate for all application
   domains.
