1. A method for identification and verification of a user at a client platform in a client/server, computer-networking system that implements an authentication server, the method using an authentication credential as a shared secret with the authentication server, the authentication credential comprising a data set (i) identifying a first enumerated pattern of fields on a frame of reference, and (ii) identifying a second enumerated pattern of fields on the frame of reference;

  • the fields in the first and second enumerated patterns having locations on the frame of reference, and numbered positions in the corresponding enumerated patterns;

    the method comprising;

    using a data processing machine or data processing machines, establishing one or more communication channels to the authentication server, and sending a user identifier via said one or more communication channels to the authentication server;

    receiving a session specific instance of the frame of reference as a result of successful identification of the user identifier by the authentication server, from the authentication server, from an application synchronized with a logical function used to produce an instance at the authentication server or from a combination of the authentication server and an application, the session-specific instance of the frame of reference having fields filled with a session-specific content, wherein the session-specific content comprises characters that are members of a set of characters;

    rendering an interface on a display including a graphical representation of the session-specific instance of the frame of reference where;

    a subset of the fields in the first enumerated pattern are populated by characters in said session specific instance identifying a first session specific set of numbered positions of fields along the second enumerated pattern, andcharacters in the fields having the first session specific set of numbered positions in the second enumerated pattern match characters in fields at locations on said session specific instance having a second session specific set of numbered positions in the first enumerated pattern;

    sending authentication response data via said one or more communication channels to the authentication server, the response data identifying said second session specific set of numbered positions in the first enumerated pattern, data identifying said second session specific set of numbered positions in the first enumerated pattern being usable by the authentication server as part of a verification process; and

    receiving a signal via said one or more communication channels from the authentication server that indicates completion of the verification process.
