Recognition of person on the basis of biometric feature is an emerging phenomenon in our society. Traditional systems to verify a person’s identity are based on knowledge (secret code) or possession (ID card), however codes can be forgotten or overheard and ID cards can be lost or stolen giving impostors the possibility to pass the identity test. The use of features inseparable form of person’s body significantly decrease the possibility of fraud.
Furthermore, biometric can offers user convenience in many situations, as it replaces cards, keys and codes. Fingerprint based authentication is one of the beneficial type of biometric technique and also it is considered one of the most practical features. Fingerprints are easily accessible, recognition requires minimal efforts on the part of the users, it does not capture information other than strictly necessary. In the examination authentication has always been a major challenge verification of the authentic candidate is not an easy task and also it consumes a lot of time and process. This reason to the design of fingerprint based exam hall authentication system, that is designed to enter only users verified by their fingerprint scan and does not allow non verified users. In 19 century formal written examinations become regular in universities, schools and other educational institution.
Examination were also increasingly employed for the selection of recruit to all the services and the professions over the ages standard testing has been the most common methodology, yet the validity and credibility of the expanded range of contemporary assessment techniques have been called into question
Power supply: The system need regulated DC power supply to power the components and the power need to be regulated because, this component need stable power supply and at the certain limit. Fingerprint module: Fingerprint scanner uses a lightsensitive microchip to produce a digital image. The working principle of the fingerprint sensor mainly depends on the processing.
Fingerprint processing mainly includes two elements namely enrolment and matching. In fingerprint enrolling, every users requires to place the finger twice. We can store the images in fingerprint module. Microcontroller: in this project microcontroller is used to store the program and through micro controller we can send the signal to the LCD, Buzzer, motor. LCD: It nothing but Liquid crystal display, we use 16*2 crystal display to show message for users. Buzzer: It is used for indication purpose, when fingerprint is not matched with the stored fingerprint then buzzer sounds. Motor: Here in this project motor is used to open and closing the door, when fingerprint is matched with the registered fingerprint then motor is start and door gets open.
Registration mode: The first step in any biometric system is collection of the biometric being used. The device used to capture the initial sample will vary depending on the type of physical trait being collected. This could be a reader or sensor used to scan a fingerprint, before using the system for the first time for authentication the user must enroll their biometric sample, a number is assigned to him/her using the keypad. The number assigned is automatically stored in the fingerprint module.
Verification mode: In this verification mode the system verifies the student by scanning the fingerprint and compares with the stored fingerprints. If the image is registered, it prints outs the individual identification no to confirm eligibility. When a wrong finger is placed on the module, it scans the image, sends to the fingerprint module. This browses through the image in its memory and if noting is found, it prints out a message stating that the person in question is has no personal details in its memory. A massage “NOT REGISTERED” is displayed on the screen.
