A system includes a control source that is provided on a server and control logic that executes on a terminal. The control logic executes on a terminal to (i) identify a plurality of attributes on the terminal, the attributes including an identifier for each of a plurality of terminal assets that include one or more of a hardware fixture, firmware, or operating system; and (ii) generate signature data from the plurality of attributes. The control source is configured to make a determination from the signature data as to whether the terminal is known or unknown.
