A Remote User Authentication Scheme for Home Access

Abstract

"Digital home security systems are becoming inevitable in modern lifestyle. For the purpose of safety, smart systems are required to be developed that themselves could recognize the legitimate visitor and only then allow him/her the access to the door. We propose a smart home access system architecture for the door lock system. This system controls the door lock via android smartphone App using WiFi as the communication protocol, WeMos D1 WiFi module embedded in the lock and the online PHP web server. With the help of cloud-based messaging service, it is easy to send a message to remote android mobile. This aspect removes the need to embed GSM module with a smart lock system. To keep track of the door status and the events like door smashing, keeping door open for a long time, we have used the accelerometer and magnetometer respectively. This system keeps itself in LAN of the home router. It avoids the access to the system from outside the LAN. The smartphone App has a password for secure access to the lock system. This system veri es the password of the user and then sends an OTP to the mobile App using cloud-based secure messaging service. Di erent possible scenarios have been considered to check the system's performance in real time. Memory space consumption and the time taken by the system in use are the challenging aspects in a home access system. The security aspect of the system does not a ect much to the operation time of the system. So, the system is e cient from the time perspective and easy to use by novice user as its mobile App."
