I agree that the level of fraud we have seen in the past has not worried the
banks, the merchants or governments.  But, in my view, widespread e-commerce
in the presence of the lack of security that currently exists will provide
scope for fraud on a scale that it will be difficult to ignore.

Whether the reaction is a sensible one is much less certain though.  I read
in the paper today that Charles Clarke is worried about this - in view of
the GAK in RIP disaster I wonder what we are now in for?
