Fingerprints are formed from the skin’s uneven surface of ridges and valleys. When recorded, a fingerprint appears as a series of dark lines that represents the high, peaking portion of the ridged skin; the white space is the valley (the low, shallow portion of the ridged skin) between the ridges. Ridges do not always form long and continuous patters. Often, ridges are shorter and stop and start abruptly. The result is a unique pattern of specific characteristics such as ending ridges or dividing ridges and dots.
The flow of the overall ridges is used to assign a fingerprint classification (loops, whorls, etc.). Minutiae information — the location, direction and orientation of the ridge endings and bifurcations (splits) along a ridge path — are then gathered and used to develop the fingerprint template.
A fingerprint is
|“||a small mark physically placed on the magnetic surface of each . . . diskette which contains certain information that cannot be altered or erased.||”|
|“||[a] set of information elements that identifies a device or application instance.||”|
