The purpose of the present invention is to propose a dual-channel identity authentication selection device, system and method. During payment or login, a security method, where one channel is used to transmit a user name, identity authentication data and devices are selected by a selection device according to the transformed user name, and the other channel is used to transmit the user name to a server, is used. When a computer terminal which may be insecure is used, another computer terminal can be used to cooperate with a server to achieve secure payment login. 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 services of banks, games and the like by combining with a good cryptographic protocol. |
