Abstract: An identity recognition pre-processing method, an identity recognition method, and devices. The identity recognition pre-processing method comprises: after any user carries his/her own mobile device and enters a pre-set nearby region of a biological feature collection device, the mobile device of the user receiving a wireless signal broadcast by the biological feature collection device, wherein the wireless signal triggers the mobile device to provide, to a recognition serving end, a group identifier of a user group to which an owner user belongs; the recognition serving end determining, from a registered biological feature set, a registered biological feature associated with each user in the user group corresponding to the group identifier, and issuing the determined registered biological feature to the biological feature collection device; and the biological feature collection device adding, to a locally built screened feature set, the registered biological feature issued by the recognition serving end. Thus, a biological feature collection device subsequently compares each registered biological feature in a screened feature set with a collected biological feature (i.e. a collected biological feature) of a user to be recognized, so as to recognize the identity of the user.
