  Fingerprint - Wikipedia, the free encyclopedia
Fingerprints are commonly held to be an infallible method of uniquely identifying an individual, but it's more an art than science: most state and federal level crime labs will not report a fingerprint match until two experts independently reach that conclusion.
Fingerprint identification (sometimes referred to as dactyloscopy) is the process of comparing questioned and known friction skin ridge impressions (see Minutiae) from fingers, palms, and toes to determine if the impressions are from the same finger (or palm, toe, etc.).
Fingerprint experts had conceded that the process they use -- matching large, evenly pressured prints taken from suspects at the police station to smaller, unevenly pressured prints from crime scenes -- is ultimately subjective and bedeviled by inconsistent standards.

 Biometrics: Fingerprint
A fingerprint is made of a series of ridges and furrows on the surface of the finger.
Fingerprint classification is a technique to assign a fingerprint into one of the several pre-specified types already established in the literature which can provide an indexing mechanism.
An input fingerprint is first matched at a coarse level to one of the pre-specified types and then, at a finer level, it is compared to the subset of the database containing that type of fingerprints only.

 Fingerprint Information
While his experience with fingerprinting was admittedly limited, Sir Herschel's private conviction that all fingerprints were unique to the individual, as well as permanent throughout that individual's life, inspired him to expand their use.
He discussed fingerprints as a means of personal identification, and the use of printers ink as a method for obtaining such fingerprints.
While he soon discovered that fingerprints offered no firm clues to an individual's intelligence or genetic history, he was able to scientifically prove what Herschel and Faulds already suspected: that fingerprints do not change over the course of an individual's lifetime, and that no two fingerprints are exactly the same.

 ABC News: Study: Fingerprint Evidence Isn't Infallible
Fingerprints taken at crime scenes are not always clear, which can lead to faulty analysis and misidentification – errors that are extremely difficult to counter, but perhaps happen a thousand times a year, says a researcher.
That research eventually cleared him, despite the fact that experts had testified that his fingerprint implicated him in the attempted murder of a police officer.
In another case, a corpse found in the Nevada desert was identified – on the basis of fingerprints – as that of a California woman who later turned up alive.

 Fingerprint
By having an individual scan their fingerprint electronically to decode information, the transmitter of the data can be certain that the intended recipient is the receiver of the data.
One concern of fingerprint biometrics is that latent prints left on the glass will register the prior user, however there already exist units that will not scan unless a "live" finger is on the glass and will only register the later imprint.
Closely associated with fingerprint biometrics is another biometric that registers the imprint left by the palm of the hand.

 Fingerprint Identification
The last several years have proved that fingerprint scanners are overwhelmingly the most successful biometric device (Davis, A. Fingerprint imaging devices/applications account for nearly 80 percent of the total worldwide biometrics market, according to Frost and Sullivan.
The first country to adopt a national computerized form of fingerprint imaging was Australia in 1986, which implemented fingerprint imaging technology into its law enforcement system (Simon, D. It has been estimated that the chance of two people, including twins, having the same fingerprint is less than one-in-a-billion (Industry Information: Biometrics, 1996).
Optical fingerprint technologies require the user to place his or her finger on a glass substrate at which point an internal light source from the fingerprint device is projected onto the fingerprint.

Fingerprint cuts any subrange of a nucleotide sequence at Gs (as if it were digested with T1 ribonuclease) and arranges the fragments in order of their U (or T) content.
It was sequenced by Pedersen and Devereux at Smithies' lab at the University of Wisconsin and at Larkin's lab at Purdue University, Spring 1981.

 infra-red spectra - the fingerprint region
The importance of the fingerprint region is that each different compound produces a different pattern of troughs in this part of the spectrum.
The pattern in the fingerprint region is completely different and could therefore be used to identify the compound.
You would then compare the fingerprint region of its infra-red spectrum with known spectra measured under exactly the same conditions to find out which alcohol (or whatever) you had.

 Daylight Theory: Fingerprints
Fingerprints are a very abstract representation of certain structural features of a molecule; before we describe them, we'll discuss the problems that inspired the development of the fingerprinting techniques used in the Daylight Chemical Information System.
Fingerprints are not so definite: if a fingerprint indicates a pattern is missing then it certainly is, but it can only indicate a pattern's presence with some probability.
Although a fingerprint doesn't indicate with 100% certainty that a particular pattern is present, it contains far more patterns total than a structural key, the net result being that a fingerprint is a far better screen than a structural key in almost all situations.

In this day and age of high-tech crime-solving methods, especially DNA typing, the lowly art of fingerprint identification sometimes seems lost.
In fact, fingerprint evidence is highly reliable and particularly accessible to juries: You don't need a Ph.D. or a scientific lecture on genetics to understand that your own fingers contain a contour map of ridges and whorls that is completely unique.
And it is increasingly popular for parents to ask local police departments or schools to fingerprint their young children, a grim reminder that children who are abducted or are the victims of other heinous crimes often cannot be identified otherwise.

 Biometrics: fingerprint
While the overall appearence of monozygotic (identical) twins' fingerprints is often similar (a and c), they differ in the fine details (the locations of ridge starting and stopping); in addition, they are no more similar to each other than to some prints of unrelated individuals (b).
Also, like twins, a clone is not a perfect copy, and fingerprints (and other non-genenic traits) will be different (recall this point when you see a movie such as The 6th day).
Some people have some skin diseases which prevent normal formation of fingerprints, and we even know the case of one family which have no fingerprints (for genetic reason, probably).

 Fingerprint FAQ
Fingerprints can be copied in the form of data sets, paper prints, wax molds, etc. It is possible with criminal technical methods to observe, analyze, and copy latent fingerprints unwittingly left behind on beer glasses or door handles.
This is because traces from the last fingerprint remain on the sensor and may be activated, e.g., by breathing upon the sensor surface.
In test reports about fingerprint sensor devices occasionally is criticized that residuals of the fingerprint of an authorized person remaining on the sensor might be activated by an attacker to gain unauthorized access (e.g., by breathing on the sensor).

Using fingerprints instead of passwords also makes life easier for families that share one home computer, since many scanners can be set up to recognize different family members.
Fingerprint scanners read your fingerprint using either an optical method similar to the way a photocopier scans an original or a capacitive method that senses the difference in electrical charges between the ridges and valleys in a fingerprint.
Still, a fingerprint scanner can be handy if you use multiple computers and have user names and passwords for all the different Web sites you visit.
