Hi all, Sam Hartman, our Security AD, reviewed the Geolocation Policy document (see http://tools.ietf.org/html/draft-ietf-geopriv-policy-12). Here is the issue he identified: " I'm trying to think about the mechanisms in section 6 of the geopriv document for reducing the granularity of location. I'm wonder though how effective these mechanisms are in cases where in addition to getting one-time location information I'm also seeing transitions in location information. As an example if I see a transition from one building to a near by building, I may well know much more about the civic location than granularity. Similarly, I'm wondering how much information monitoring transitions in geodetic location would help me in discovering where someone is in the best case. I.E. where they are near a discontinuity in the rounding. " Thanks to Sam for providing a detailed review of our document. In had a discussion with Sam about this issue. I agreed that some information is disclosed when you cross the boundaries. More information is disclosed when the user picks small regions for the boundary (e.g., only room numbers are not shown). I believe it is useful to document this issue. So, I would need feedback from the group. a) Do you think that this is indeed a problem? b) If yes, how should we document this aspect?
