Abstract

A highly secure Dialogic Enciphered Dynamic PIN System is used to prevent fraud of credit card, debit card and any account access on-line and POS transactions effectively with low-cost and convenience. Each cardholder or account owner has a small special passcode protected calculator to store the operation addend and long secure formula for each account. Card issuer sends back an inquiry PIN number after receiving a request of transaction, the cardholder or account owner selects the card or account from the calculator, enters the transaction amount, inquiry PIN number, and secure PIN number as memorized, then the calculator does special calculation to the transaction amount or base by the sequence of secret formula + inquiry PIN number + secure PIN number, and generates an answer PIN number which is sent back to card issuer. The same calculation is done in the card issuer side to authenticate the user and authorize the transaction at the same time with high security.
