Abstract: Identity identification preprocessing methods and systems, and identity identification methods and systems are disclosed. 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.

Abstract: A method includes: pre-generating a key pair including a first public key and a first private key; acquiring identification information about a mobile terminal; encrypting the key pair including the first public key and the first private key using the identification information to obtain a first encrypted public key and a first encrypted private key and saving same; when a service key is encrypted, encrypting the service key using the first private key to obtain an encrypted service key; when the service key is decrypted, decrypting the encrypted service key using the first public key to obtain the service key; acquiring data needing to be encrypted/decrypted of the mobile terminal; and encrypting/decrypting the data using the service key. The security of the data can be protected off-line with low cost and without hardware protection, so that the data cannot be intercepted and tampered with.

Abstract: This disclosure relates to identification preprocessing. In one aspect, a method includes receiving at an identification server, and from a mobile computing device that has entered a predetermined area surrounding a biometric feature collection device, a group identifier of a user group to which a user of the mobile computing device belongs. The group identifier is transmitted by the mobile computing device in response to the mobile computing device receiving a radio signal broadcast to the predetermined area. The user group is one of multiple user groups. Based on the group identifier, the identification server selects, from a stored registration biometric feature set, a registration biometric feature associated with each user in the user group. The identification server adds the registration biometric feature to a screening feature set established for the biometric feature collection device. Biometric feature-based identification is performed on the user using the screening feature set.

Abstract: A display instruction associated with a graphic code is received from a terminal device and at a client computing device. A biometric feature identifier associated with a biometric feature that is verified by a server is obtained by the client computing device. A code string that includes the biometric feature identifier is generated by the client computing device. The graphic code that includes the code string is displayed at the client computing device, to permit completion of a service by the terminal device using the graphic code.
