Abstract: With the increasing demand for safe and automatic access control systems, the project proposes a multi-layer authentication-based smart lock system integrating biometric certification, OTP-based access and infiltration system. The system is applied to the system using Arduino Uno, a GSM module, an ESP32-CAM and a solenoid lock. The first certification method uses a fingerprint sensor, allowing authorized users to directly unlock the solenoid lock. If the fingerprint authentication fails, the system sends the "unauthorized access detected" notification to the registered user through GSM. The second method introduces the OTP-based certification, increasing the safety through two-factor authentication (2FA). Users generate an OTP by entering a pre-set fixed code, which can be modified for the extra safety. The OTP generated is transmitted to the mobile device registered via GSM, and on the correct entry, solenoid lock trigger. To prevent unauthorized access, the system incorporates an intruder detection mechanism it includes ESP32-CAM, uses bot API to send an image of infiltrators to the defined Telegram account in this phenomenon when a wrong OTP has been entered. This real-time alert system ensures remote monitoring and increases security. Integration of biometric verification, OTP authentication, and intruder detection makes this system highly reliable for smart homes, offices and high-protection areas.
Keywords: Smart lock, biometric authentication, OTP-based access, GSM module, ESP 32-CAM, intruder detection, Arduino UNO, Telegram API, IOT security, two-factor authentication (2FA).
