    Kingsley> Can a data access policy deliver unlinkability ?


Absolutely not.  I think you're talking past each other, but the data
access policy on the accessed resource cannot deliver unlinkability in
the sense that I and I think Ben are using.  The data access policy on a
centrally stored credential may be part of delivering unlinkability with
regard to certain parties in some security schemes.

If you believe that data access policies are part of unlinkability, then
I'd suggest starting to see if we're talking about the same definition
of unlinkability.
