<p>A system and method for enabling a user of a remote controller to transmit a PIN over a wireless connection in a secure manner. In accordance with the present invention, a terminal device, used for conducting transactions with a service provider, is coupled to the service provider via a data network and a display such as that of a television or personal computer. The same remote control device (either IR or RF) that is used to operate the display is also used to transmit an encoded PIN to the terminal. Session-specific coding rules for encoding the PIN are displayed to the user to guide him through the encoding process. Upon receipt of the encoded PIN, the terminal decodes it, validates it and, if appropriate, permits access to the requested transaction or service. <IMAGE></p> |
