Using sessions, $HTTP_HOST, form keys, $HTTP_REFERER, ip address,
On a session you can record the user_agent on the first page, the ip, the
host, and check on the form's action page. Form keys are some number you

between page transitions or things that you can invent.
Not 100%, but the more, the best.
