After any user carries a mobile device to a predetermined nearby area of a biometric feature collection device, the mobile device of the user receives a wireless signal broadcast by the biometric feature collection device. The wireless signal triggers the mobile device to upload an auxiliary identification factor other than a biometric feature of the owner and an identity of the owner to an identification server. The identification server establishes a mapping relationship between the received identity and the received auxiliary identification factor. After subsequently obtaining a collected biometric feature uploaded by the biometric feature collection device, the identification server can perform two-factor-based user identity identification based on the previously established mapping relationship and the collected biometric feature. ## Claims ### Claim 1 A computer-implemented method comprising: receiving, by a mobile device of a user, a wireless signal, wherein the received wireless signal is broadcasted by a biometric feature collection device to a predetermined nearby area of the biometric feature collection device;
