Identity identification and preprocessing

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations 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;
• generating, by the mobile device of the user, a first set of data, wherein the first set of data comprises an identity and an auxiliary identification factor of the user;
• invoking, by the mobile device of the user, a client program corresponding to an identification server based on the received wireless signal, wherein the client program is installed on the mobile device of the user;
• and
• uploading, by the mobile device of the user, the first set of data to the identification server based on the received wireless signal, wherein the first set of data is configured to enable a mapping relationship between the auxiliary identification factor and the identity, and wherein the mapping relationship is used to perform biometric feature-based identity identification on the user at the biometric feature collection device.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations 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;
• generating, by the mobile device of the user, a first set of data, wherein the first set of data comprises an identity and an auxiliary identification factor of the user;
• invoking, by the mobile device of the user, a client program corresponding to an identification server based on the received wireless signal, wherein the client program is installed on the mobile device of the user;
• and
• uploading, by the mobile device of the user, the first set of data to the identification server based on the received wireless signal, wherein the first set of data is configured to enable a mapping relationship between the auxiliary identification factor and the identity, and wherein the mapping relationship is used to perform biometric feature-based identity identification on the user at the biometric feature collection device.
