<p>The purpose of the present invention is to propose a dual-channel identity authentication method and system. When a computer terminal which may be insecure is used, another computer terminal can be used to cooperate with the computer terminal to achieve secure payment. In the method, it is impossible for the bank card number and password to simultaneously appear in a device which may be insecure. The method can be used for network payment, and can simply and securely solve the problems of identity authentication and payment data security in the process of using the services of banks, games and the like by combining with a good cryptographic protocol.</p> |
