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 The manual authentication and human intervention of the present systems has been replaced by digital means.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 marks in ink of the lines on the tip of a finger used for the purpose of identification.
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.
Our project “High tech voting machine” is very useful to recognize the authenticated person. In personal computer citizen finger print, name and other datas are maintained. In our project finger print scanner is connected to PC via USB port. Person finger print is captured and given to PC where new finger print is compared with authenticated finger prints; if it matches it will give some binary value to parallel port which is given to microcontroller. Controller accepts the data and displays the authentication and will also be ready to accept the voting. If any unauthenticated person comes for voting, PC will give some other binary value to controller, which displays unauthentication of the person along with the alarm.
