Abstract
A method and a system for authenticating an electronic financial transaction conducted between a user owning a terminal and a third party via two-way transmissions between the terminal and a cable distribution hub which includes a validation server. The method comprises the following: (a) extracting a first identification attribute of the terminal from a first transmission message sent from the terminal to the cable distribution hub, which corresponds to a first set of user identifiers residing in a database accessible by the validation server; (b) extracting a second identification attribute of the terminal from a second transmission message sent from the terminal to the cable distribution hub, which corresponds to a second set of user identifiers residing in the database accessible by the validation server; (c) comparing the first and second sets of user identifiers to validate the identity of the user; (d) interrupting the electronic financial transaction if there is a discrepancy between the two sets of user identifiers; and (e) allowing the electronic financial transaction to proceed if there is no discrepancy between the two sets of user identifiers.
