+// This file is temporary for the duration of the evaluation of the

+// *Two domains appear in effective_tld_names.dat and so were manually removed.

What is the privacy story here?

Doesn't this give visibility into per-domain browsing history?

Don't you need to use something like
https://sites.google.com/a/chromium.org/dev/developers/design-documents/rappor
if you want to be doing this?

The privacy protections are:

1) It's a big list, so although we receive information that a user visited
page(s) under one or more of these domains, we don't know which. We could
improve the privacy protection by making the list bigger, but at a cost of
larger binary size. The current list takes ~800 bytes in compiled form.
2) It's a diverse list, since the domains are chosen based on technical aspects
of the site (specifically use of stale-while-revalidate for third-party
subresources) and popularity rather than content. This means that visiting a
site on this list doesn't reveal anything particular about a user.
3) These are popular sites, so many users will visit them, making the fact that
a user visited one or more of them very low in information.

Rappor permits us to get specific information in the aggregate without revealing
specific information about any individual. In this case we don't need specific
information at all--we are not interested in which domain was visited, only how
long it took.

I have cleared it with the Chrome Privacy Team.
