RE: Issue-39: Tracking of Geographic Data

Aleecia,

The geo-location discussion was on the first day and fairly early in the event.  I believe the conversation has progressed significantly and as we narrow in on the "cross-site" element of "tracking" I'm struggling to see how geo-location fits into the "cross-site" model.  If the group feels that IP Address derived geo-location should not be used across sessions if the user has DNT activated, that makes sense to me but I'm not sure if geo granularity is important in this context (any geo vs. Zip4).

Reminder: we had a fairly lengthy discussion about geoIP in the context of how identifying zip plus 4 is (about 12 households) and had a general sense that it is hard to claim there is no tracking if you can identify location that closely. I can pull the call minutes and/or prior email threads where Shane argues against zip plus 4 being ok if that is helpful context.

Is it perhaps the concept of across sites, over time? I think this is what Jeff is getting at too, when he talks about multiple data sources.

If ad network just uses the IP address that accompanies HTTP request to provide relevant content or ads, OK. If ad network remembers it in a profile it retain about you based on cross site activity, that is not OK, when DNT signal is sent (absent some other exception).

Yes?

nope. not what I meant. I'm trying to find a better way
to express the cross-data aggregation around IP geolocation.
