Abstract (en)
[origin: WO0179959A2] A system and method for the protection of electronic communications and data transmission using multiple, single-use key codes is described. When a data transmission or other transaction is initiated through the use of a device or medium specific identification number (SIN) and a personal identification number (PIN) by the central or a remote node, the first code in the recorded sequence is transmitted to the receiving node. If the code received corresponds, to the first available in the recorded sequence, the requested communication or transaction is verified and approved. If the key codes do not correspond, the communication or transaction is rejected. Once the first code in the sequence is used, it is erased or otherwise inactivated in both the central and remote nodes, and the subsequent code is activated for use in the following communication or transaction.
