Comment(by mikeperry):
From the FTC's report on DNT, page 53 (PDF page 69):
http://www.ftc.gov/os/2012/03/120326privacyreport.pdf
> "The Commission commends recent industry efforts to improve consumer
control over behavioral tracking and looks forward to final
implementation. As industry explores technical options and implements
self-regulatory programs, and Congress examines Do Not Track, the
Commission continues to believe that in order to be effective, any Do Not
Track system should include five key principles:
>
> First, a Do Not Track system should be implemented universally to cover
all parties that would track consumers. Second, the choice mechanism
should be easy to find, easy to understand, and easy to use. Third, any
choices offered should be persistent and should not be overridden if, for
example, consumers clear their cookies or update their browsers. Fourth, a
Do Not Track system should be comprehensive, effective, and enforceable.
It should opt consumers out of behavioral tracking through any means and
not permit technical loopholes. Finally, an effective Do Not Track system
should go beyond simply opting consumers out of receiving targeted
advertisements; it should opt them out of collection of behavioral data
for all purposes other than those that would be consistent with the
context of the interaction (e.g., preventing click-fraud or collecting de-
identified data for analytics purposes)."
While we don't meet all of those right now (we miss !#2 due to tbb-
usability bugs, and !#3 due to our lack of updater, and !#4 due to the
above bugs in this ticket's description), there's no technical reason we
couldn't meet them all. However, the task is impossible for the actual
DNT:1 header. In particular, there's no way for DNT:1 to ever satisfy
requirements !#1 or !#4 (and arguably even !#5).
