Personal identification numbers (PINs) are frequently used to verify the identity of a user and for other security purposes. It is possible to crack the password via shoulder surfing or thermal monitoring while using PIN-based password authentication. Handsfree eye-blink PIN authentication. Instead, PIN input techniques leave no tangible evidence of the user's activity, making them a more secure alternative to entering a password. PIN generation is known as eye blinks-based authentication, in which the PIN is generated by finding the eye blinks in successive picture frames. This project presents a real-time application that integrates eye blink-based PIN input, face recognition, and OTP to avoid attacks by shoulder surfing and thermal tracking (One Time Password).
