Implementation of Knock Based Security System

Gunjan Jewani

Security is one of the most critical concerns in daily life. In this paper a novel human–machine interface is being integrated in a security system. The system applies the action of knocking as the input interface to unlock a door without using keys. First, the unlock areas on the door are set. When a user knocks on the door, the system obtains knocking information from vibration sensors in the door. A pattern-recognition algorithm subsequently identifies the knocking pattern of the user, including the knocking areas and the knocking sequence. According to the simulation results, the accuracy of identifying the correct knocking areas is between 85% and 90%. This system is best suitable for corporate offices, ATMs and home security. A knock based security system (KBSS) system using a Piezo sensor and ARDUINO . The ARDUINO Leonardo controls the system, the expected outcome includes: 1. Locking and Unlocking of the door through patterns based on knocks. 2. The unlocking of the door through a mobile phone incase if user forgets the pattern using the Bluetooth module. 3. Automatic locking of the door for 30min if intrusion is detected and an alert is sent to the authorized user.
