Tracking has privacy implications regardless of whether it is pseudonymised or anonymised, as long as single individual profile is created. Very few network advertisers, for example, currently connect a profile to any information that would generally be considered "identifiable", but these programmes are still heavily scrutinised. See, for example, the discussion in the FTC's self-regulatory principles, here: http://www.ftc.gov/opa/2009/02/behavad.shtm So it's hard to believe that any do-not-track solution would include a carveout for pseudonymous or anonymous profiling. A more relevant question, though, and one that I have not seen a clear answer to, is whether it would also apply to aggregate tracking - the kind of statistical analysis that does not capture individual profiles, but does do some kind of tracking at the very lowest level to create those statistics (unique visitors, for example). Some regulators already consider this too to be privacy-invasive (see, for example, Germany's dealings with Google Analytics: http://eu.techcrunch.com/2009/11/24/google-analytics-illegal-germany/) -----Original Message----- From: public-privacy-request@w3.org [mailto:public-privacy-request@w3.org] On Behalf Of Thomas Roessler Sent: 17 November 2010 12:29 To: Rigo Wenning Cc: Thomas Roessler; public-privacy@w3.org Subject: Re: do not track list?

It would be interesting to look at deployment (and compliance) incentives for this technology, and at what it actually means for a user not to be tracked. Also, what's the scope of this sort of exercise -- Do I opt out of all tracking, including pseudonymous profiles? Do I only opt out of tracking that identifies me? Thoughts? -- Thomas Roessler, W3C <tlr@w3.org> (@roessler)
