I've been thinking about how to do authentication and user recognition
for my site without cookies. I had this idea but I don't really know
if its possible at all.
If I got the IP address from the request could I use ARP to get the
MAC address for that IP? If so I could compare that MAC address with
a (previously obtained) database of addresses and if it matches they
would automatically be logged in. So I could preauthorize my friends
and remember other users once they have signed up.
It seemed like a cool idea but is this at all possible or am I just
insane?
Thanks,
Leo
