Geographical Location on the Internet: Architectures for Privacy and Policy
Jon Peterson, NeuStar, Inc.

Date: Thursday, February 12
Time: 11:45am - 12:30pm
Location: California Ballroom C

Location information is frequently propagated on the Internet today without any appreciable privacy controls, creating a troubling opportunity for potential abuse of user location by advertisers or other unwelcome parties. The Geographical Location and Privacy (GEOPRIV) working group of the Internet Engineering Task Force (IETF) has investigated a number of problems related to the distribution of geographical information on the Internet, from both a security angle and a policy angle.

The result of the IETF's work is a generic framework for the creation and distribution of location information on the Internet that enables confidentiality and policy directives, which are abstracted from the format of the location information. By coupling privacy controls with location information, the GEOPRIV object format ensures that usage rules are carried with location information throughout its lifecycle. Because it is founded on MIME and XML, GEOPRIV has applicability to the Internet's most prevalent applications (including email, the Web, and voice over IP). This presentation introduces the GEOPRIV work and shows its potential applicability to one important service, the dissemination of location for Internet-based emergency services.
