Geographic Location/Privacy (geopriv) ------------------------------------- Charter Last Modified: 2011-01-07 Current Status: Active Working Group Chair(s): Richard Barnes Alissa Cooper Real-time Applications and Infrastructure Area Director(s): Gonzalo Camarillo Robert Sparks Real-time Applications and Infrastructure Area Advisor: Robert Sparks Technical Advisor(s): Lisa Dusseault Mailing Lists: General Discussion:geopriv@ietf.org To Subscribe: https://www.ietf.org/mailman//listinfo/geopriv In Body: subscribe Archive: http://www.ietf.org/mail-archive/web/geopriv/index.html Description of Working Group: The IETF has recognized that many applications are emerging that require geographic and civic location information about resources and entities, and that the representation and transmission of that information has significant privacy and security implications. We have created a suite of protocols that allow such applications to represent and transmit such location objects and to allow users to express policies on how these representations are exposed and used. The IETF has also begun working on creating applications that use these capabilities, for emergency services, general real-time communication, and other usages. The GEOPRIV working group is chartered to continue to develop and refine representations of location in Internet protocols, and to analyze the authorization, integrity, and privacy requirements that must be met when these representations of location are created, stored, and used. The group will create and refine mechanisms for the transmission of these representations that address the requirements that have been identified. The working group will work with other IETF working groups and other standards development organizations that are building applications that use location information to ensure that the requirements are well understood and met, and that no additional security or privacy issues related to location are left unaddressed as these location information is incorporated into other protocols. It remains a goal of the GEOPRIV working group to deliver specifications of broad applicability that will become mandatory to implement for IETF protocols that are location aware. This working group will not develop location-determining technology. However, the IETF acknowledges that information used in the location- determination process will in some cases need to be carried over the Internet. Where necessary, this working group will develop protocols or protocol extensions to encode location-determination data structures defined elsewhere. This working group will not develop technologies to directly address any particular regulatory requirements (e.g. 9-1-1). The group will continue to coordinate with any other IETF entities that are working on those problems to ensure the technologies created here meet the needs of those entities, and that the authorization, integrity, and privacy requirements on the mechanisms provided by these technologies continue to be met.
