Machine-to-machine communication based smart home security system by NFC, fingerprint, and PIR sensor with mobile android application

The rapid growth of burglary and theft over the last few years has been threatening to the vulnerability of traditional home security systems. In this research, this hazardous circumstance persuades the authors to develop a machine-to-machine (M2M) communication based smart home security system. Here a multi-layer home security system (HSS) has been developed which maintains six levels of security and necessary control responses against unwanted burglars and intruders. As a part of this development, the first security level uses Near Field Communication (NFC) tag, the second level uses a secured password system and the third level uses fingerprint authentication. After that, a GSM module embedded with the proposed HSS sends the logged password to a remote server via M2M communication. The server encrypts the password and noties the homeowner via an android based mobile application whether the person is an authenticated person or not. In the final stage of security, if an intruder wants to enter the room by breaking the password without NFC tag and fingerprint encryption, a Passive Infrared (PIR) motion sensor will work and sounds a buzzer for alarm. Therefore, the automatic and embedded operation of the proposed HSS makes it more secure, reliable and robust than other traditional systems.
