The advantages of the live fingerprint capture system are as follows in details.
Guarantee of high quality of fingerprint images
- It will bring about further increase of quality of images.
- It will make the density amplitude feature of images much better.
- It will eliminate the error zone caused by hustle feature.
Guarantee of high efficiency of data conversion (fingerprint classification) of the AFIS (Automatic Fingerprint Identification System).
The data conversion of TP cards requires three processes.
- Capture of fingerprint images (This process is to capture cards via a scanner.)
- Encryption of detailed minutiae
- Modification
The three jobs of work have a certain difference in their effort rates according to the characteristics of the using system, but, in general, 15% for capture, 3% for encryption and 82% for modification.
If a live fingerprint reader is used for capture of images, there will be no need of the process for capture mentioned above. It will eventually reduce 15% of the whole process efforts, the rate for capture.
Besides, it will bring about pretty high efficiency of modification with increase of accuracy of distilling minutiae points by more than 10%.
The above-mentioned material is about the analysis on 1,000 fingerprints.
It takes enough 20 seconds per fingerprint to modify errors of 5% averagely.
Acceleration of Capture of Fingerprint Images Capture of fingerprints by using fingerprint ink is complex in its process and takes long time.
It takes long time to capture fingerprints by using fingerprint ink, and with its complicated process.
When fingerprint ink is used for making out TP cards, you have to capture all of the ten fingerprints on a new card again if even one of the captured fingerprints is unobvious. That is why it takes long time and the images are generally fallen into bad quality. This puts the person in charge of that work into a very nervous state.
But the use of a live fingerprint reader can make you do repeated work with one fingerprint as a unit, so it will brings about further increase of work efficiency. And it is possible to install a fingerprint reader in any place, which ensures a rapid and thorough capture of fingerprints of all the objects.
Guarantee of Immediate Search of AFIS
Introduction of a live fingerprint reader ensures rapidity of criminal investigations.
It is the work of data conversion that spends a great deal of efforts and time in introduction of the AFIS.
Long-time of data conversion will bring an obstacle to uncover of crimes and leads to overrun of criminal prescription, which means impossibility of arrest of criminals.
But the use of a live fingerprint reader makes will bring light to criminal records and unresolved cases as soon as the fingerprints are captured.
Convenience of Fingerprint Registration
It is unnecessary to use ink, which
- Avoids discomfort to the enrollee.
- Does not require production of such old tools as fingerprint ink.
- Simplifies the process of making out TP cards.
- Prevents fingerprint cards from physical and chemical changes due to humidity, temperature, dirt and filth.
- Is sanitary.
Permanent Preservation of High-quality Image Data
It can permanently preserve image data of high quality.
Quality of images of TP cards gets worse and worse for some reasons, whereas that of images captured through a live fingerprint reader will never get changed.
Simplification of Business such as Fingerprint Data Administration
It does not need the previous large-scaled system of storage and administration of fingerprint cards.
Generation of Several Image Data via One Accurate Input
There is no need of enroll fingerprints repeatedly, when it is necessary to make and store several TP cards of a person.
Portable Use
For its small size and lightness, it can conveniently be used in prisons and terminal police units including police stations as well as in central places.
Compatibility
It can be combined with the most general-used IBM PC/AT compatible computer.
Immediate Distant-transmission of Fingerprint Data
It can transmit the detailed minutiae point data of images to a distance at a rapid speed via the standard communication network.
