Abstract: A method for logging in an online system through an authentication server is provided. The authentication server records an authentication account of the authentication server, and an alias, a login username of the online system, and an authentication device that are associated with the authentication account. The method includes steps of: the online system sending a user-input name to the authentication server; the authentication server finding the authentication account; the authentication server, when determining that the user-input name conforms with the alias, sending a query message to the authentication device that is associated with the authentication account thus found; the authentication server, when receiving a confirmation message from the authentication device, providing the login username to the online system; and the online system, when determining that the login username has been registered on the online system, allowing an Internet device to log in to the online system.

Abstract: A method is to be implemented using a network authentication device and a user end for authenticating the user end. The network authentication device stores hardware information associated with unique identification codes of hardware components of the user end. In the method, the user end executes a terminal program for scanning the hardware components to obtain the identification codes, for establishing a hardware list according to the identification codes, and for automatically sending to the network authentication device verification data associated with the hardware list without user operation. The network authentication device verifies identity of the user end based on the verification data and the hardware information.

Abstract: In a network authentication method, a content-provider server redirects a user terminal to an identity verification server for acquiring therefrom an encrypted web address signed with an asymmetrical private key and downloaded from a downloading unit. The user terminal transmits hardware scan data associated therewith to the identity verification server upon determining, based on the encrypted web address and an asymmetrical public key from the downloading unit, that the identity verification server is currently valid to perform identity verification. The identity verification server verifies the identity of the user terminal based on relationship between the hardware scan data and pre-stored reference hardware scan data.

Abstract: A network authentication method is to be implemented using a network authentication device and a user end for authenticating the user end. The network authentication method includes the steps of: configuring the network authentication device to store hardware information associated with unique identification codes of hardware components of the user end; when it is intended to verify identity of the user end, configuring the user end to execute a terminal program stored therein for scanning the hardware components thereof to obtain the identification codes of the hardware components, for establishing a hardware list according to the identification codes thus obtained, and for sending to the network authentication device verification data that is associated with the hardware list; and configuring the network authentication device to verify identity of the user end based on relationship between the verification data received from the user end and the hardware information stored therein.
