The Smart Door Unlocking System integrates state-of-the-art technologies to redefine access control. By combining advanced techniques such as Local Binary Pattern (LBP) histogram analysis, facial recognition, and OTP authentication, the system ensures unparalleled security and convenience. Unlike conventional lock-and-key methods, this innovative solution employs LBP histogram analysis to extract intricate facial patterns, enhancing the accuracy of user identification. The integration of facial recognition further bolsters security by providing a biometric layer of verification. Additionally, the OTP authentication generates unique one-time passwords sent to users' mobile devices, adding an extra dynamic level of protection, even in the event of a facial recognition mismatch. The system's ingenious utilization of the piezoelectric effect serves as a tamper detection mechanism, triggering OTP alerts upon detecting unauthorized access attempts. This amalgamation of cutting-edge technologies guarantees not only secure access but also a seamless and user-friendly experience for both residential and commercial applications.
