Sign On Authentication Ari Silversteinn 08-15-2005

Is there a way to automatically authenticate a user, not the user's
computer, when he logs in to a website? The reason for this is to validate
that a multiple choice test that is taken was performed by Bob X and not by
Charles Y in a distance learning application.

No additional hardware can be used (such as fingerprint reader); there
would have to be no reconfiguration of Bob's computer since Bob is
incapable of performing any such task.

If this is possible, then can Bob also be identified if using *any*
computer not just his own.

Isn't this normally done with a username and password prompt? It can be
improved with token-based authentication like SecurID or Defender.

This is a notion known as "individual identification" and "individiual
authentication."

It's normally done with a username and password. The username
identifies a unique user. The password set by that person
authenticates that user that hopes to confirm the user is who they say
they are.

If by automatic you mean the user doesn't have to enter anything, the
answer is "no, with your requirements, there's no practical way to do
this."

If you're willing to give up strong authentication, you could email
URL's to specific users, each of them uinque, and containing an
encoded username to uniquely identify them.

However, if someone happens to get hold of that email maliciously or
by a manager forwarding their email to all their subordinates and
saying "take the is test" then you've lost authentication, and
everyone who got the email will be indistinguishable.

Can you control the access to the physical terminal?

If so, yes, this access control is good for identifying the users, if the
terminals are secure.

If not, no, you cannot make this secure.

Yes, this can be accomplished through the use of bar code e-mail.
