Re: [ietf-privacy] [perpass] New Version Notification for draft-cooper-ietf-privacy-requirements-00.txt

I am seriously considering trying to gain enough weight that I can fit this onto myself as a tattoo:

"The information radiated even from protocols which have no obvious connection with personal data can be correlated with other information which can paint a very rich behavioral picture, that only takes one unprotected link in the chain to associate with an identity."

On brief consideration, I cannot think of a single _new_ protocol for which opportunistic encryption shouldn't be the default, for reasons other than interoperability with an existing protocol that has a significant installed base. Even in such cases, I think it would be useful to be very clear that communication in the clear for interoperability is an exception, a "legacy" mode, "to be deprecated", or other not-very-happy-sounding words that mean "we realize we're stuck with it in this case but that's really no excuse."

Opportunistic encryption everywhere reduces the content of this radiated information, as well as reducing the risk of unprotected links holding some associable identifier. So exceptions will have to be very well justified if an aim of this work is protection of privacy against pervasive surveillance.
