        The use of computers in public places in increasingly common
        in everyday life.  In using one of these computers, a user is trusting
        it to correctly carry out her orders.  For many transactions, particularly
        banking operations, blind trust in a public terminal will not satisfy most
        users.  In this paper the aim is therefore to provide the user with authenticated
        communication between herself and a remote trusted computer, via the 
        untrusted computer.
        \par
        After defining the authentication problem that is to be solved, this paper
        reduces it to a simpler problem.  Solutions to the simpler problem
        are explored in which the user carries a trusted device with her.  Finally,
        a description is given of two camera-based devices that are being developed.
