Fingerprint
A visible graphic reproduction of a holder’s fingerprint uppermost layer (fig. 1). It is a relief lines (papillary pictures). Their structure is determined by a number of friction ridges divided by grooves. These friction ridges form a complex skin pattern which has the following characteristics:
- individuality — a structure of papillary ridges is individual by its location, configuration and mutual arrangement. They form a special pattern which is unique for every person;
- relative stability — permanent structure of the uppermost skin layer which remains unchanged throughout the life;
- ability to recover — After the skin damage papillary ridges recover to the initial state.
Fingerprint identification is the most common, effective and reliable biometric technology.
