How about the verifiability of identity courtesy of Linked Data tweak.
Security like Privacy is much deeper when social factors come into play.
This is where policies come into play. Of course, you can't construct
meaningful data access policies without verifiable identity, courtesy of
the kind of authentication accorded by the WebID protocol.
