Method for binding card, terminal device, authentication server and storage medium

A method for binding card, applicable to an authentication server, the method comprising:

• receiving a user identifier sent by a terminal device and for logging in a target application by a user of the terminal device without any card information, wherein the terminal device is a user terminal used by the user for a first time for binding card and contains no card information for the user, and the target application is on the user terminal of the user;
• in responsive to a real-name authentication on the user based on the user identifier being determined to be not passed, generating an identity information obtaining request;
• sending the identity information obtaining request to the terminal device, so that the terminal device is to obtain identity information of the user, wherein the identity information of the user includes at least an identification card number of the user and a biometric feature of the user;
• receiving the identity information sent by the terminal device;
• performing a real-name authentication on the user based on the identity information to confirm that the user of the terminal device is a real user as the user presented by the user identifier by matching the biometric feature of the user with biometric features stored in a database;
• in responsive to the real-name authentication on the user based on the identity information being determined to be passed, storing a binding relationship between the user identifier and a result of the passed real-name authentication;
• in responsive to the real-name authentication on the user is passed, searching at least one first card bound to the user identifier;
• and
• sending card information of the at least one first card to the terminal device, wherein the card information is for the terminal device to send a binding request to a card issuing server corresponding to the card information, wherein the binding request comprises the card information without the user entering any card information, the user identifier and a secure element identifier of a secure element of the terminal device, and the binding request is for the card issuing server to bind the card information to the user identifier and the secure element identifier uniquely representing the terminal device such that the card information is bound to the terminal device being used by the user,
• wherein the searching at least one first card bound to the user identifier further includes:
• in responsive to the real-name authentication on the user being passed, firstly finding at least one second card corresponding to the identity information of the user just passed the real-name authentication from cards stored on the authentication server;
• and
• then determining the at least one first card bound to the user identifier from the at least one second card under a condition that the real-name authentication on the user is determined to be passed based on the user identifier.

A terminal device comprising a secure element, comprising:

• an obtaining module configured to obtain a user identifier for logging in a target application by a user and a secure element identifier of the secure element, wherein the terminal device is a user terminal used by the user for a first time for binding card and contains no card information for the user, and the target application is on the user terminal of the user;
• a sending module configured to send the user identifier without any card information to an authentication server, wherein the user identifier is for the authentication server to search at least one first card bound to the user identifier based on a preset binding relationship between at least one user identifier and cards stored on the authentication server;
• and
• a receiving module configured to, in responsive to a real-name authentication on the user based on the user identifier being determined by the authentication server to be not passed, receive an identity information obtaining request sent by the authentication server;
• wherein the obtaining module is further configured to, in responsive to the identity information obtaining request, obtain identity information of the user, wherein the identity information of the user includes at least an identification card number of the user and a biometric feature of the user;
• the sending module is further configured to send the identity information to the authentication server for the authentication server to perform a real-name authentication on the user based on the identity information to confirm that the user of the terminal device is a real user as the user presented by the user identifier by matching the biometric feature of the user with biometric features stored in a database;
• to store, under a condition that the real-name authentication on the user based on the identity information is passed, a binding relationship between the user identifier and a result of the passed real-name authentication;
• to firstly find at least one second card corresponding to the identity information of the user just passed the real-name authentication from the cards stored on the authentication server;
• and to then determine the at least one first card bound to the user identifier from the at least one second card under a condition that the real-name authentication on the user is determined to be passed based on the user identifier;
• the receiving module is further configured to, in responsive to the real-name authentication on the user being passed, receive card information of the at least one first card sent by the authentication server,
• the sending module is further configured to send a binding request to a card issuing server corresponding to the card information without the user entering any card information, wherein the binding request comprises the card information, the user identifier and the secure element identifier, and the binding request is for the card issuing server to bind the card information to the user identifier and the secure element identifier uniquely representing the terminal device such that the card information is bound to the terminal device being used by the user.
