Smart access control management method based on blockchain technology

Abstract

The invention provides a smart access control management method based on a blockchain technology, comprising the following steps: a visitor sends an access request to a management chain through a client of the visitor to establish an access information document; an access object audits the access request, and if the audit passes, access permission information is generated; face information acquisition is carried out on the visitor, and the acquired visitor face information and the corresponding allowed access time are stored as access control comparison information to a database layer; an access control system receives a piece of face information and reads the visitor face information corresponding to the current time from the database layer for comparison, and if the comparison is successful, the access control is opened. According to the method in the invention, the blockchain technology is used to realize effective management of the visitors; on one aspect, a face recognition function is combined to complete the automation and systemization of the access process, thereby reducing the manual management cost; on the other aspect, the entire access process information of the visitor is stored in the blockchain database, thereby ensuring the accuracy and completeness of the information and facilitating tracing and management.

Description

technical field [0001] The invention relates to the technical field of blockchain, and belongs to an intelligent access control management method based on blockchain technology. Background technique [0002] At present, the access control system has made some improvements to the visitor functions, such as generating a verification code and sending it to the visitor. The visitor shows the verification code when visiting, and then enters after the identification is successful, so as to realize the management of the visitor. [0003] However, there are still defects in this method. First, the verification code does not guarantee that the visitor is the person himself, and needs to be re-identified by the access control management personnel. Second, the management information of the visitor is still managed by the system of the visitor. It is easy to lose, miss and miss, and difficult to trace. Contents of the invention [0004] The purpose of the present invention is to prov...
