Two-dimensional code access control system based on face feature values, and running method thereof

Abstract

The invention discloses a two-dimensional code access control system based on face feature values, and a running method thereof. The system includes a user terminal, and an image collecting device, afront end identifying and processing device and a background server which are sequentially connected. The running method of the system comprises the following steps: a user sends a two-dimensional code registration request to the background server through the user terminal; the background server sends an access control two-dimensional code to the user terminal according to the request; the image collecting device collects the face image of the user and an access control two-dimensional code image; the front end identifying and processing device extracts face feature information of the face image, parses the face feature information included in the access control two-dimensional code image and compares the similarity between the two pieces of the face feature information, and the backgroundserver verifies the validity of the access control two-dimensional code; and after the similarity meets conditions and the validity verification of the access control two-dimensional code is passed,an access control is controlled to be open. The validity of the two-dimensional code user and the validity of the used two-dimensional code are verified based on the information provided by the user in order to perform security management of the access control.

Description

technical field [0001] The invention relates to the field of access control based on biometric identification, in particular to a two-dimensional code access control system and operating method based on facial feature values. Background technique [0002] QR code access control is a new type of access control application technology that has emerged following the development of smart phone terminals, computer network technology, and Internet of Things technology. Two-dimensional code, namely QR Code (Quick Response Code), is a coding method that has been widely used on mobile devices in recent years. It can store more information than traditional bar codes (Bar Code), and can also represent More data types, such as: characters, numbers, Chinese and so on. Due to the generation of the two-dimensional code, the production cost is low and the convenience is good, and it has gradually been widely used in the access control system. [0003] Commonly used two-dimensional code acc...
