One of the things that can partition anonymous messages is
a pattern
to the headers. For example, if somebody uses an odd header
and the
final remailer doesn't remove it, the sender could
compromised.
Parsifal gets around this by removing all headers except
those needed
to send the message, but, even there, patterns can
sometimes be
discerned.
For example, if somebody uses the same four m2n gateways,
in the same
order, he might begin to stand out.
There must be a number of other things in headers that tend
to
partition senders, and which could be 'normalized' for all
senders,
thus lessening the problem.
People may object, however, to any such tampering. Would
it, for
example, be objectionable, in your opinion, if a final
remailer were
to replace the mail2news gateways with 3 or 4 of its own
choosing,
putting them in a random order?
Another example of possible partitioning might be the
structure of a
reply: the number of lines between paragaphs, the number of
> left
between the original message and the reply. Things like
that could be
normalized without affecting the sense of the message, but,
again,
some people might find it objectionable.
I suppose the reply to such objections would be that the
message is
going to be changed by definition, since it has been
encrypted and
various headers removed, so anything that can be done to
keep the
sender unknown should be welcomed by the sender.
That's certainly how I would feel, but others may feel
differently.
So I'm asking for ideas as to what can be normalized,
either in the
headers or in the message, and whether any, or all, of such
normalization is objectionable.
