The base map in the embedded face NVR face library is the basis of a face recognition algorithm, and the conventional base map information management method is that a User performs operations such as creation, editing, deletion, search, import, export and the like through an IE browser or a UI (User Interface) of NVR. However, with the demands of users, the number of face base maps in the face library is increasing, and some face base maps need to be increased by up to 10w, and such a face base map management mode has the problems that: 1. when the face base map is added, information can not be added, and only after the addition is finished, the attribute information (name, sex, name family, birthday, native place, certificate type, certificate number, company name, company address and the like) of each face base map is edited in a user interface, so that a large amount of time cost is increased for the maintenance and the use of a user; 2. the method does not support batch modification of face attribute information: when the human face base map information in the human face library needs to uniformly modify the same type of information, the editing operation of each related base map needs to be carried out, so that the workload is large and the efficiency is very low; 3. the face attribute information is not reused: and editing operation is required when the attribute information of the face base map in each face NVR device changes.
