IOT Case Study Home automation
The Internet of Things (IoT)
The Internet of Things (IoT) is an ever-growing network of smart objects. It refers to physical objects capable of exchanging information with other physical objects. Nowadays, safety and security have become a basic necessity for metropolitan society. This proposes a security system for the IoT environment. It prevents intrusion in Home, Bank, Airports, Offices, University, or any location with a security system. The primary objective of our project is to reduce human work by designing and implementing a security system. A system that offers controllability through a handheld mobile phone and PC using IoT.
Intrusion Detection System (IDS)
To detect malicious activity or policy violations, we use an Intrusion Detection System (IDS), which detects any intrusion or violation and typically reports to the administrator. This system includes Anomaly-based techniques for intrusion detection and signature analysis using the Haar algorithm to differentiate between legitimate persons and intruders thus raising accuracy in authorizing the legitimate person and providing access to private/personal zones, therefore reducing the risk of sending false alerts/alarms.
Automation and Infrastructure
Automation is the primary key factor of security; we use Raspberry pi3 and relays to control any electric appliances that can be implemented in the home, office, bank, etc. The administrator can monitor the place through an application with live feedback and control an automated environment. Infrastructure It observes a deviation from the normal behavior of the system or the users. The system later compares it with the current activity. When a deviation is observed, an alarm/GSM-based message is generated. It detects the false alarm/message rate of the system, not because the entire scope of the behavior of an information system may be covered during the Initial phase. The system includes a PIR module that constantly monitors the Home or Workspace. When the PIR module detects an intruder, it sends a signal to the microcontroller, and the controller is connected to a module and also to an alarm system. The System transmits an alert signal to the user’s mobile phone. The system also employs a thumb reader that controls the opening and closing of a safety locker door. Thus, the system uses a Wi-Fi module and controller to control the security system from the user’s mobile phone using any device with a potential internet connection detected the system will be augmented with the parameter monitoring security subsystem. This will supplement information about home monitoring, and fingerprint protection which can give false alarms to nearby residents and the owner of the house in case of theft.
Working
We will be using different IDS (intrusion detection system) techniques. Anomaly detection, this technique detects abnormal behavior in the system using a PIR sensor. The normal usage pattern is base and alerts are generated when usage deviates from normal behavior and then the camera is activated. When the camera is activated the detected person will be examined, and the encryption/decryption process to the user exceeding authorization by face recognition technique (image processing). Signature analysis is a technique used to compare the examined data with the specifically predefined defined data (also known as signatures) and provides authorization, thus enabling accuracy in the intrusion detection system and lowering the false alarm/message rate. An infrared sensor is used to see the difference between PIR and Other Obstacles.
System Specification
To prevent intruders from entering the home and provide access to only legitimate persons. We implement different IDS techniques i.e. Anomaly-based and Signature analysis using different sensors and wireless cameras for the detection of intruders. If any intruder is detected, then the detected intruder image is examined with the previously stored database, and a notification is sent to the owner. If the person is legitimate, then access is provided to the home. Enables the owner to monitor his/her home with live feedback through an application and provides home automation through the application.
