Abstract: The present application provides identity registration and authorization methods using biometric feature information of user. In one example method, a terminal device receives biometric feature information of a user that is to be verified in association with a service processing request. The terminal device can then match the received biometric feature information to be verified with a pre-stored biometric feature of the user, where the pre-stored biometric feature of the user is associated with a corresponding identifier. In response to matching the received biometric feature information to be verified to a particular pre-stored biometric feature of the user, a private key store is searched for a private key associated with the identified of the particular pre-stored biometric feature of the user. In response to determining that no private is associated with the identifier, a user identity of the user is registered with a server.

Abstract: A request is received from an intelligent terminal by an intelligent wearable device for enabling a one-time password function, and the intelligent wearable device is configured with an embedded algorithm chip. Provisional data from a provisioning server is obtained using the intelligent terminal. The provisional data is verified. If the provisional data is verified, the verified provisional data is stored on the intelligent wearable device. Using a micro operating system, the embedded algorithm chip is invoked to generate a one-time password, and the one-time password is displayed on a computer display of the intelligent wearable device. The one-time password is configured to permit a verification server to verify the intelligent wearable device.

Abstract: An intelligent terminal scans, as a scanned identification code, an identification code that is displayed by an intelligent wearable device. A wireless broadcast signal is transmitted by the intelligent terminal to identify the intelligent wearable device. A response to the wireless broadcast signal is received by the intelligent terminal and from the intelligent wearable device, where the response includes an identification code. The identification code is extracted by the intelligent terminal from the response and as an extracted identification code. The intelligent terminal compares the scanned identification code and the extracted identification code. If it is determined that the scanned identification code and the extracted identification code are the same, the intelligent terminal is paired with the intelligent wearable device.
