Time-synchronization type two-dimensional code access control method and system

Abstract

The invention discloses a time-synchronization type two-dimensional code access control method and system. The time-synchronization type two-dimensional code access control method comprises the following steps that access control equipment generates a two-dimensional code of a dynamic password; a user uses mobile equipment to carry out code scanning, analysis and signing on the two-dimensional code, and sending to a server; the sever finishes authentication of access control and person identity by a time synchronization technology and a signing technology. The time-synchronization type two-dimensional code access control method and system disclosed by the invention have the advantages that the deployment is simple, the cost is low, the safety is high, the expansibility is good, the personapplication range is wide, the behavior of persons in swiping the access control can be ensured to be authentic and credible, and high-level safety management for persons can be achieved.

Description

technical field [0001] The invention belongs to the field of intelligent safety management, in particular to a time-synchronized access control method and system based on two-dimensional codes. Background technique [0002] Enterprises, institutions, parks, and communities at all levels have access control equipment for safety and standardized management. At present, relatively old-fashioned keys, inductive door cards and relatively advanced password identification equipment are widely used. Because password identification has many shortcomings such as easy disclosure, only one-way control, and high cost, relatively cheap inductive door cards have become the mainstream choice in China, but there are still many problems, such as: [0003] (1) The process of making, issuing, recycling and reissuing cards is cumbersome; [0004] (2) The cost of the card is relatively high, and the cost of a single door card is 3-5 yuan; [0005] (3) The card is inconvenient to carry, difficu...

AI Technical Summary

Problems solved by technology

[0003] (1) The process of making, issuing, recycling and reissuing cards is cumbersome;

[0004] (2) The cost of the card is relatively high, and the cost of a single door card is 3-5 yuan;

[0005] (3) The card is inconvenient to carry, difficult to store, and easy to lose;

[0006] (4) The security of the built-in information in the card is not high, and it is easy to be cracked and copied;

[0007] (5) The traditional access control "recognizes the card but does not recognize the person", so it is difficult to manage flexibly in the background, and it is impossible to track the record of opening the door in real time

[0008] In addition, this method cannot effectively manage the entry and exit of temporary personnel and invited visitors, while the traditional "manual visitor registration" has frequent false registration accidents, scribbled and blurred handwriting, poor image of handwritten registration, and piles of documents Find problems such as difficulties
