Design and implementation of intelligent door system based on WeChat

Abstract

As intelligent mobile devices become more popular, people have stronger and stronger intention to control the Entrance Guard System (EGS) with mobile devices (Abraham, Security Technology Research Report, 12, 2014 [1]). However, most of EGSs cannot connect to the mobile devices wirelessly and they also need to improve their performances such as security, practicability, and intelligence. Therefore, this research proposes a WiFi EGS with double authentication secure random dynamic code system based on WeChat. The user needs to send a certain command firstly and feedback the status of indicator lights on the controller before he gets the permission to open the door. If the user who does not belong to the accessible group, he needs to apply for the random dynamic access code from the owner with WeChat. The EGS can make sure that the user has been at the door by the feedback status of the indicator lights on the door controller. The random dynamic code applied by the visiting user can be used only once. Without installing any App, all the users can open, close, and check the lock with mobile phone just by following the WeChat public number on the lock. So, the EGS is very easy to use and can also help the owner to let his guests enter the door in security even he is out. Some experiments have verified that the EGS has many goodness such as convenience, security, and low cost, thus have a wide range of application.
