Abstract: An identity identification method comprises: tracking a current location of each user to determine a current grid area each user is located; receiving an identification request sent by a service terminal; the identification request comprises first location information and biological characteristic information of a target object; determining a first grid area where the service terminal is located based on the first location information; obtaining biological characteristic information of each user with respective current grid area being the first grid area; completing an identity identification according to the biological characteristic information of the target object and the biological characteristic information of each user in the first grid area. A device and server based on dynamic rasterization management are further provided.

Abstract: This application provides an identity Identification method for a fixed-point authorization, and devices and servers therefor, comprises receiving an identification request sent by a service terminal; wherein the identification request comprises terminal information and live body biological characteristic information of a target object; the terminal information comprises a terminal merchant number and terminal location information; determining at least one valid user of the service terminal according to the terminal information, and obtaining biological characteristic information of each valid user; wherein the valid user has a direct or an indirect authorization relationship with the service terminal; completing the identity identification according to the live body biological characteristic information of the target object and the biological characteristic information of each valid user.

Abstract: This application provides a method for near-field information authentication, device, electronic device and computer storage medium therefor, comprising: obtaining a current location information of the object to be authenticated, determining a target grid area where the object to be authenticated is located; receiving the identity authentication request sent by the target service terminal; determining effective users of the target service terminal according to the information of the target service terminal, determining biological characteristic information of each valid user; performing identity authentication based on the live body biological characteristic information of the object to be authenticated and the biological characteristic information of each valid user. When information authentication is performed on the object to be authenticated, this application is realized through the live body biological characteristic information of the object to be authenticated.

Abstract: This application provides an authenticating method for identity information, and device and server therefor, which relate to the technical field of identity authentication. The method is executed by a server, the server is respectively connected in communication to a target authentication device and a user terminal; the method comprises: receiving a first identity information of a user to be authenticated and identification information of the target authentication device sent by the target authentication device; performing a legality authentication on the first identity information of the user to be authenticated based on stored first identity information of a legal user and the identification information of the target authentication device; sending the authentication result to the target authentication device. This application may effectively protect personal identity information, improve security, reliability and convenience of identity authentication, and enhance user experience.

Abstract: This application provides an operation determination method based on expression groups, apparatus and electronic device therefor, and relates to the technical field of image processing. The method is executed by an electronic device. The method comprises: obtaining a current human face image of a target object; performing a live body human face identification on the target object based on the current human face image, determining whether an identity of the target object is legal according to an identification result; the live body human face identification comprises a live body identification and a human face identification; if legal, obtaining a current expression group of the current human face image; determining an instruction to be executed corresponding to the current expression group; performing an operation corresponding to the instruction to be executed.
