Finger print using library management system
Published Thursday 6 October 2011 by gk inFinger print using library management system
Abstract:
With the advent in technology, the existing systems are developed to have in built intelligence. This is of greater importance in places where human identity is required. The manual authentication and human intervention of the present systems has been replaced by digital means. Of all the digital systems, Embedded Technology predominates as it overcomes the drawbacks of all the existing mechanical and electronic systems.
Definition of a Fingerprint
There are four main types of fingerprints, loops, whorls, arches, and abstract. However, no two fingerprints are alike. A fingerprint is a pattern of lines on the tip of a finger used for the purpose of identification.
What Is Fingerprinting?
What Is Fingerprinting?
Fingerprinting is the process of identification based on the impressions of the ends of the fingers. The impressions consist of patterns formed by ridges that cover the skin of the fingertips. Fingerprints provide one of the most reliable methods of identification. No person’s fingerprint is identical to any other human being. In most cases, fingerprints remain the same throughout any person’s lifetime. Ridges on the person’s fingerprints only change as a result of surgery, disease, or an accident.
The Use of Fingerprints
Fingerprints are often used in the investigation of crimes. Prints found at the scene of a crime may help identify the subjects. Fingerprints that match police records are strong evidence in court. Fingerprinting may help prevent crime. For example, banks, military bases, and government buildings use computers to check fingerprints of employers before they can be admitted to different areas. A number of states allow children to be fingerprinted to help identify them if they are later reported missing.
In our project “ELECTRONIC LIBRARY MANAGEMENT SYSTEM USING FINGER PRINT SENSOR” allows only authorized person to access the library and also does not allow the person take more book than he is authorized for. The scanner scans the fingerprint and image is given as input to the PC which maintains the database regarding the names and number of books taken. If the number of books taken exceeds the number he is allowed for, microcontroller raises the alarm and gives a LCD display.
