Android Application for Advanced Security System based on Voice Recognition, Biometric Authentication, and Internet of Things

Nowadays, the smart home automation system has a significant role in makes daily work easier and efficient. Keeping room keys is an obstacle. Therefore many research has been proposed however the lack of a security system makes the automation systems less trustworthy and unreliable, as well as limited control distances. This paper purposes speech recognition to control the door and only registered people can access it.The proposed system uses microcontroller NodeMCU ESP8266 with a wifi connection to control actuators. The android application has features tracking history control menu, real-time monitoring menu, registration menu, and speech recognition control. The system security consists of a login system, biometric authentication, and specific speech command. The system also uses restful API technology and a java programming language for conducting data transactions either android or microcontroller with a database server.The results show a stable response time of 2 seconds for the microcontroller to control the smart home locally and distantly in one city. The system also proves the registration menu, tracking history control and real-time monitoring perform well with 100% success. The 3 levels of security system also have 100% success with each level must have a value true before doing control of the smart home. This level of security proves the application system is not easy to hack by anyone, very reliable and trustworthy.
