Security System For Highly Secured Places Based On Internet Of Things

This paper proposes a security system which is specially designed for highly secured places like bank, corporate office, educational institutions etc. There are so many places in the world like the mentioned places needed to be secured and the entry should be restricted without permission. These places can be secured by the implementation of Internet of Things (IoT). There will be an electronic door at the entry of the place and that door will be controlled by an IoT platform. The platform will receive signal from the authorized person and transfer the signal to the device through internet. Moreover, this system will ensure proper security by using other methods, these are biometric authentication and personal identification number. There are two different methods at the entry and the exit. Biometric authentication is utilized in case of taking entry to that place whereas personal identification number is used in case of exit. So, use of different methods is also an advantage of this system. The biometric registration will be done by taking only the finger print of authorized person. The access to IoT platform will also be allowed to authorized person only. The microcontroller is NodeMCU and ATmega328P. NodeMCU has built in wifi module which will connect the device to internet. ATmega328P is interfaced with FPM10A fingerprint sensor and 4x4 matrix keypad to take fingerprints and PIN respectively. The program is developed in ‘C’ language using Arduino IDE.

Introduction

Our system can be defined as a security system that has been designed to ensure the security of any place by mounting it at the entry. It is basically an electronic door which is controlled remotely by the implementation of Internet of things (IoT) and again with authorized finger print and Personal Identification Number (PIN) from door end. It maintains the security by different way of authorization to ensure a backup option to protect the system security from any kind of tempering to any way of authorization. IoT based electronic door will be used to any specific highly secured place where the owner or authorized person will have the control over the system remotely by the use of a platform with internet. It is basically a demand of modern era since the internet is available in every place. Again, the authorized person will have secured entry to the place with biometric registration and with just the fingerprint door will be opened to avoid excessive procedure from the door end. The exit through the door is protected by PIN to make sure the entered person is really authorized and to permit the person to get out of the place by ensuring the security twice by using different methods.

Methods

In the initial step, any one method is applied either finger print or IoT platform to open the door. In case of finger print sensor when the given finger print matches with the enrolled finger prints it sends signal to Arduino Uno to operate the Servo Motor Door. In case of IoT a password is sent to the IoT Platform via Messenger which sends signal to NodeMCU to operate the Servo Motor Door. On the other hand, from the opposite side of the door using Matrix Keypad a PIN is given to send data to Arduino Uno to operate the Servo Motor Door.

Hardware implementation of the project is consisting of different types of devices. Arduino UNO R3 (Atmega 328p based project development board) and NodeMCU (An open-source firmware based on ESP8266 wifi-soc) are the core of this hardware.

Conclusions

This project is especially for security purpose to ensure security of any specific place. By implementing this we can keep so many expensive wealth and documents safe. With further research and innovation, is project can be extended as per requirement to ensure better security. Many organizations such as bank, school, college, university, corporate office etc. can adopt this system to make safe entry to there. Specially banks can mount this electronic door at their vault entry. So, that place will be safe by ensuring only authorized person’s entry and can be controlled and monitored with the IoT platform from the head office. This system can be extended by adding more features to make it safer.
