Thus spake Katya Titov (kattitov@yandex.com):
Testing: tor-browser-gnu-linux-i686-2.2.37-1-dev-en-US.tar.gz Platform: Debian 6.0.5 Processor: Intel(R) Pentium(R) CPU B950 @ 2.10GHz
I think people can leave off CPU. What we care about here is if you're using the x64 or i386 packages.
- https://panopticlick.eff.org/ - one in 223,553, 17.77 bits of identifying information
Great test url, Katya. We have issues with how Panopticlick is run, though. It has inherent bias against any change from established norms, even if that change is in the direction of uniformity amongst a population.
In particular, the largest sources of entropy in Panopticlick come from our solutions to fingerprinting issues. The largest source of bits (screen resolution) come from what is perhaps our most effective reduction in information available to the fingerprinter: https://trac.torproject.org/projects/tor/ticket/4810#comment:3
Perhaps we should ask EFF to provide us with the Panopticlick source code or so we can run a unique instance to evaluate TBB users only?
I've created this ticket for that: https://trac.torproject.org/projects/tor/ticket/6119
If you have any comments or suggestions wrt the above, please comment on the bugs or create a new tor-qa thread rather than reply here.
