One of the important conditions of increasing the AFIS hit ratio is a use of the latest digital technologies of inputting dactyloscopic information, dedicated to replacing traditional ink fingerprinting and scanning of paper record cards with the help of flatbed scanners. |
|
The digital technologies of input based on application of electronic fingerprint scanners, allow images of fingerprint patterns to be fixed most precisely and thereby enable law-enforcement agencies to form high-quality dactyloscopic files. |
|
High quality of prints guarantees high accuracy of automatic recognition and coding of images in an AFIS, and as consequence, increase of its major search characteristics (reliability, selectivity, operating speed). |
|
Besides cardinal improvement of quality of fingerprint and palmprint files, the application of live-scan devices allows some more major problems arising at constructing the systems of fingerprint identification to be solved: |
|
|
|
|
Providing the immediacy of input of the fingerprint information in an AFIS (the stage of creating and scanning paper record cards is excluded). |
|
|
Transmitting information from the system of electronic fingerprinting to an AFIS through telecommunication channels. |
|
Minimizing the impact of the human factor when gaining fingerprint data. State-of-the-art systems of electronic fingerprinting automatically control the accuracy and quality of live-scanning and require no special training and no highly skilled operators to operate the device. |
