Abstract: ABSTRACT A PIN AUTHENTICATION SYSTEM WITH FINGERPRINTS FOR EACH DIGIT The present invention discloses a PIN authentication system with fingerprint for each digit to provide an added layer of security to the existing PIN-based authentication systems. The system incorporates a number pad embedded with fingerprint sensors on each digit to allow users to enter a PIN with corresponding fingers. An input module directs the user-entered credentials to an Arduino microcontroller connected to a multiplexer, which manages multiple fingerprint sensors. Advanced Encryption Standard algorithm is made use by the system to secure the fingerprint templates and associated PIN digits, which are then stored in a NoSQL database for data management. The verification module retrieves and decrypts the stored data and compares them with the user-entered data. The comparison results are interpreted by the authentication module to authenticate the user. A digital display guides the users throughout the process and displays authentication results. This system is suitable for high-security systems like banking, where security is of major concern.
