Electronic access control system of dynamic bar code

Abstract

The invention discloses an electronic access control system of a dynamic bar code. The electronic access control system comprises a mobile terminal, a service logic module, a bar code module and an access control module. According to the electronic access control system, a user registers and binds the terminal on a system, and when the user needs to access an entrance guard, the user applies for the permission of the entrance guard; the system generates a dynamic password, distributes the permission, and codes the dynamic password to the bar code after encrypting the dynamic password, pushes the dynamic password to a user terminal, and synchronizes the dynamic password to an access controller; the user scans the bar code on the access control system after acquiring the bar code, and the access control system scans the bar code to obtain the content included in the bar code and decrypts the content to obtain a password to judge whether a door is opened or not. The electronic access control system dynamically generates the bar code including password information and issues the bar code to the terminal user, thereby providing a convenient and rapid electronic entrance guard access method based on the dynamic bar code.

Description

technical field [0001] The invention relates to technical fields such as mobile terminals, system software, and electronic door locks, and more specifically, relates to an electronic access control system with a dynamic barcode. Background technique [0002] With the development of mobile communication services, especially the development of third-generation mobile communication service technology, mobile communication and the Internet are becoming more and more closely integrated, and mobile value-added services are becoming more and more abundant. As a portable device, a mobile terminal carries more and more various functions. [0003] The traditional electronic password door lock uses an IC card or the user enters a fixed password to control the switch. The user needs to obtain and carry the IC or apply for a fixed password through the traditional method before using it. For the user, the use method and process are more cumbersome. At the same time, Fixed passwords are e...

Problems solved by technology

[0003] Traditional electronic password door locks use IC cards or users to enter fixed passwords for switch control. Users need to obtain and carry ICs or apply for fixed passwords through traditional methods before using them. For users, the use method and process are more cumbersome. At the same time, Fixed passwords are easy to lose and spread, and there are great hidden dangers in security, and users need to remember them
