Industrial production surety factor increasing by a system of fingerprint verification

摘要

The article describes a new method of a fingerprint verification. A research purpose has been a verification of integral transformations applying possibilities with help of Fourier and Fourier-Mellin transformation as a tool for fingerprints images verification. The proposed method does not require broad preprocessing, it eliminates partly inaccurate finger place on a sensor (shift, rotation), it compensates partly fingerprint deformations (scale change, skin elasticity) and lower fingers quality (too dry fingers), it enables automatic processing and evaluation without an operator input. The proposed method, using a registration and comparative criterion of modified phase correlation can take up 91.7 % of the right fingerprints and reject just 8.3 % of them. The fingerprint verification can be used for following and controlling of technological processes; expensive or dangerous equipments, technologies or property protection from illegitimate using or misusage, and for an authentication of entry into buildings.
