Biometrics-based personal authentication system that use physiological (fingerprint, face) or behavioral (speech, handwriting) traits are becoming increasingly popular, compared to traditional systems that are based on tokens (key) or knowledge (password).Fingerprint-based identification is one of the most important biometric technologies which have drawn a substantial amount of attention recently. Fingerprint technology is so common in personal identification that it has been well established. Each human has unique owns fingerprint, even the twin have different fingerprint. So fingerprint recognition is useful in security law application. The electronic lock using fingerprint recognition involves a process of verifying the user's identity by using fingerprint recognition as a key to the electronic lock. This work highlights the development of fingerprint recognition system using LPC2148 microcontroller to recognize the input fingerprint image from the stored data. Then the information of the recognized fingerprint image will be store in database for verification authorized user. These fingerprint recognition systems are based on the hypothesis that the human fingerprint is unique. It is important to validate the individuality of fingerprint in order to use the fingerprint image for security related system. If the user's fingerprint has a positive match then GSM module gets triggered and the registered user gets an OTP on mobile phones, we have to enter the OTP then the door will open. If unauthorized person access the buzzer connected will be initiated to alert the people or the security official in the surroundings.
