Arduino Based Smart Fingerprint Authentication System

Security is the serious issue looked by everybody when we are far from our family unit. In the present situation acceptable answer for the above issue isn’t yet found. Introduced here is an electronic securing framework which Arduino assumes the job of the preparing unit. Arduino which is a microcontroller board has a place with at uber family. It is an open source straight forward instrument. It can detect, screen, store and control application. Access control for the entryway is accomplished utilizing Arduino Mega 2560 board. This task displays a keyless framework for locking and opening purposes utilizing a predefined PICTURE secret key and OTP. Unauthorized person access is ensured by sending OTP and PICTURE password to ADMIN to get OTP and PICTURE password where the person needs to contact the ADMIN to get OTP and PICTURE password. It is entered through the 2.8″ TFT touch display, which display all the UI messages and takes inputs from user. In case of authorized user, the system allows fingerprint sensor to validate the person followed by sending either PICTURE password or OTP via SIM using GSM module to the user registered mobile number saved in database (local SD card) in order to access the door. If the entered password matches, door will be opened automatically otherwise a message showing incorrect password will be displayed on TFT display and a notification will be sent to the owner that the security was tried to be breached. This hardware project achieves 3 levels of security with commonly available component and also consumes less power. This system also has an option to unlock the door through SMS in case of emergency by the ADMIN.
