Geographic Location/Privacy Working Group (GEOPRIV)

GEOPRIV (http://www.ietf.org/html.charters/geopriv-charter.html Links to an external site.) an IETF working group tasked with establishing a means of disseminating geographic data that is subject to the same sorts of privacy controls as presence is today.

The requirements for GEOPRIV are given in RFC 3693. Security threats are examined in RFC 3694.

“A Presence-based GEOPRIV Location Object Format” is defined in

RFC 4119 based on earlier work done in formulating the basic requirements for presence data -- the Presence Information Data Format (PIDF) and a means of distributing these object described in RFC 4079.

Transcript

[slide441] But there's also a working group within IETF called GeoPriv. And it's the geographic location privacy working group. And they've been trying to understand, how can you scope the geographic location information to provide privacy? So for instance, I might be willing to disclose to you that I'm in room KA211 this afternoon starting at 1 o'clock. But this afternoon at 1800, maybe I don't want to disclose to you my location because you don't have any need to know it. But you might be willing to disclose to some of your friends, oh yes, I'm in Stockholm. And if you happen to be in Stockholm this weekend, let me know and we'll meet and go whatever. But you don't need to tell them your exact geographic coordinates. So one of the things that GeoPriv introduces is the idea of being able to have a means of describing a location object, but scope them in terms of accuracy. So instead of always giving very precise, you can give to some people less precise location information. And they've described a presence information data format to describe objects.
