A fingerprint is the impression left upon any surface with which the finger comes in contact under pressure.

• The fingerprint pattern of any one individual remains unchanged for life.

• Twins, triplets, quadruplets and quintuplets have completely different prints

• No two people have exactly the same fingerprints.

• All animals in the order Primates have fingerprints

A and C are twins

• The first year for the first known systematic use of fingerprint identification began in the United States is 1902.

• The New York state prison system began to use fingerprints for the identification of criminals in 1903.

• During the first quarter of the 20th century, more and more local police identification bureaus established fingerprint systems.

• In 1924 the Identification Division of the Federal Bureau of Investigation (FBI) was established to provide one central repository of fingerprints.

• In 1992 the Identification Division was re-established as the Criminal Justice Information Services Division (CJIS).

Fingerprints are now processed through the Integrated Automated Fingerprint Identification System.

• The fingerprints are submitted electronically or by mail, processed on IAFIS, and a response is returned to the contributing agency within two hours or less for electronic criminal fingerprint submissions and twenty-four hours or less for electronic civil fingerprint submissions.

Fingerprint processing has been reduced from weeks and months

to hours and

minutes.

Human fingerprint patterns fall into three main groups: whorls, loops, and arches.

Loops the most common type,

accounting for about 65% of all fingerprints.Whorls

account for 30% of fingerprints.

Arches account for 5%

When we will be rolling the print from “nail edge to nail edge”. For the fingers on the right hand, we will be rolling from left to right.

Thumbs are rolled in the opposite direction as the fingers: right to left.

• Using the ink and paper method, roll the finger on the ink pad so that the entire fingerprint pattern area is evenly covered with ink.

Rolling Prints

• The ink should cover from one edge of the nail to the other and from the crease of the first joint to the tip of the finger. Using the right amount of ink is of vital importance.

Too little ink and the impression will be too light.

Too much ink and the fine details will run together.

Plain or Flat Prints

• Press the index finger of your right hand onto the ink pad.

• Make sure that the finger is covered in ink.

• Press onto the appropriate spot on the fingerprint card.

• Repeat for each finger and thumb.

Visible – fingerprints that can be seen with the

naked eye. Example: in blood or paint

Plastic – fingerprints that leave an impression on objects.

Example: soap or wax

Latent – fingerprints that are invisible. Example: on glass

Image quality◦ Sharpness◦ Contrast◦ Distortion

Resolution – higher is better◦ Too low and we cannot detect the minutiae

Sensing area◦ Average fingerprint is about 0.5” x 0.7”◦ Large area (1.0” x 1.0”) ensures that overlap effects (leading to false rejections) are reduced
