DESIGN AND IMPLEMENTATION OF OTP BASED DOOR LOCKING SYSTEM

Abstract

Vulnerability to criminality is emerging as a new social problem as the incidence of single-parent households rises rapidly. The fear of stranger visitors is known to be the main worry for single female households. The proposed system's goal is to give additional security measures that may be employed in both homes and offices. The secret word for security is first stored in the Electrically Erasable Programmable Read Only Memory [EEPROM] in this innovation. If the user inputs the proper password, a randomly generated OTP is delivered to the user's device via Bluetooth for two-way verification. The system will be unlocked and the required task can be started if the entered OTP matches. If either the password or the OTP is incorrect, access is prohibited, and the user is given a limited number of opportunities (3 chances in the proposed system). Our main goal is to use wireless (Bluetooth device) and embedded (Microcontroller) technology to create an integrated home security system. When compared to other security systems, the suggested solution delivers a low-cost service with guaranteed high security.
