The forensic development of fingerprint I.D.

In the past no one really knew the potential that the single fingerprint had. It was use to sign on contracts but that was just about it . until Sir Francis Galton was the first to use his knowledge in solving criminal cases at Scotland Yard in England. In 1900 he introduced the technique of comparing prints. He based much of his work on the observations of Sir Edmund Henry and, together, their approach was called the Galton-Henry System. In I903 the first finger prints were put on file in a file data base in Scoland Yard, England. they used ink and paper to get the finger prints before everything was digitalized.

The Development of Printing and Scanning Fingerprints

Companies that make biometrics security equipment are now creating scanners that detect blood flow to make sure the finger is still alive because Robbers in Malaysia cut off a man's fingers so they could steal his Mercedes and it would have been easier to solve if they knew it was dead. Automated fingerprint scanning might even be used as your bank ID and locks on your doors.

No two people have been found to have the same fingerprints. There's a one in 64 billion chance that your fingerprint will match up exactly with someone else's.. The AFIS(Automated Fingerprint Idenitfication System)which has the largest fingerprint Database has over 31 million civil prints and fingerprints from 73,000 known and suspected terrorists.

Today, digital scanners capture an image of the fingerprint. To create a digital fingerprint, a person places his or her finger on an optical or silicon reader surface and holds it there for a few seconds. The reader converts the information from the scan into digital data patterns. The computer then maps points on the fingerprints and uses those points to search for similar patterns in the database. This digital scanner is called Live Scan and was founded in 2007 in Covina, California



The Live Scan is the same system in the Iphones with Fingerprint ID just in a smaller form.
