(A) stands for automation. In the old days, you must compare the person use two cards with fingerprints on them to know, if they match. This System of "old" card is replaced with an automated system which you can compare fast and do much more than one person ever can handle simultaneously.
F stands for fingerprints. Image fingerprints can be captured using a card or device that is a close cousin to the scanner. All fingerprints eventually must be in an electronic format to the automated portion of the work, so the scan tab.
(I) means to be identified. Someone is recognized fingerprint image parzyscie to the image in the database. I am speaking of images, but as the match goes typically is significantly less information in the database, then the actual image. There are characteristics of fingerprints, which can be saved and searched at much faster than the actual image.
(S) stands for the system. This System consists of a computer and software. This include scanning stations, review of stations. There are many different ingredients that work together to identify fingerprints into AFIS.
What is the AFIS?
These systems are mainly used for prosecution and may be very large systems. Largest AFIS has hundreds of millions of fingerprints and find matches within a few seconds. For this kind of processing systems can end in a somewhat complex.
Many agencies may band together to one large (AFIS), which can be used by multiple people at once. Helps reduce the costs for each agency and increases much more-a better system than if each agency set out to build their own AFIS. Most agencies will also network with other systems add to the efficiency and the chances of finding a match.
As time goes by AFIS are becoming faster and faster and matching algorithms get more advanced and better, as companies learn more and develop better systems.
Why is the imprint of an important aspect of identification? The most important feature of fingerprints is that fingerprint is unique in the world. In other words, are there other fingers exactly like the ones on your fingers. Although not all persons in the world are in the fingerprinting system, even the largest system has two fingerprints, which are exactly the same. This allows the ideal biometric (which means the function of your body) because you can uniquely identify a single person.
Together with just your finger tips are other prints, the prints are added to the AFIS added with Palm and the sides of the hand.
Eventually there will be other biometrics, which will be added to the vast Ocean of fingerprint information. Iris and Facial recognition, the names of the two. DNA can even be used to identify the people, in particular, that the DNA is also another aspect of the human body that is unique for each individual on the planet.
You may wonder, how does the AFIS. Comparison images would be ineffective and tedious, even for a computer. Perhaps some day the comparison images will be meaningful, but computers are not enough for the job because of the speed and bandwidth constraints. So what is used for comparing and matching fingerprints? Typically, it is simply a characteristic fingerprints, which are matched. This includes points where ridges end points, where the ridges split, the direction that the spines are placed and even periods. Selected key features are elected on a fingerprint minutia points (approximately 200 of these are created for the rolled fingerprints. Of course, the more is better). It is these minutia that are matched by the AFIS to find the best match for your fingerprints.
Fortunately, the computer never has a vote on a fingerprint match. Usually must occur at the end of the process of matching the examiner thoroughly check your computer and make sure it is really a game. At this time there is no substitute for the good of an expert when it comes to deciding if two fingerprints are a match.
Once you have found agency which usually requested fingerprint search will receive full disclosure of the identity of the person (called the rap Sheet). This might all be less than 30 minutes. New FBI IAFIS system this time can be significantly reduced.
AFIS is getting faster all the time, so the time it takes for a search get shorter and shorter.
Why AFIS you and me?
If you are a criminal may be more familiar with the AFIS, than to care for themselves. If you are not then you may be curious about Criminal AFIS has you can do? Because fingerprints are such easy biometric fingerprint-capturing is finding more and more applications in the daily lives of people beyond the legal issues.
For example, fingerprint machines can be granted access to areas that need to be secure, such as the instrument of Government, a laboratory, hazardous areas, where someone who is familiar with what lies beneath the doors to get hurt or even their own front doors. Imprint you can work much better than a doorknob that is key. The person who would like to have access keep a key to the door with them all the time. Eliminates the need for someone "remember their keys". Your fingers stay on their bodies.
Vulnerability of impressions
Security relies on other interesting topics. Because the fingers may be removed or falsified, there are still alternative methods which are being developed. If the fingerprint was fool proof would be needed for all other biometric record.
All we have seen the movie, where the guard gets his finger removed or manually and the offender has taken appendage to restricted areas.
Protect your property
Most people don't realize that their fingerprints are owned by them and give them to anyone who asks about them may be like giving them your favorite toys and never see it again. Problem with fingerprints, could also be used against you, therefore, must always be judicious about which you can give it to. Make sure you're doing this because of the good and fair. For example, you got a job where they require put a finger on finger reading machine for the building in which you work. This seems like a fair compensation for the entry in the place of employment.
Most people don't think about putting their fingerprints. In this article only encourages caution, not paranoia.
The future of
The future of the AFIS will other machine, where a person will walk through and it will download the information to all biometric fingerprints, face, Iris, and you will not really do anything, simply walk through it.
Edit machine would have direct application in the airport. This computer will identify someone and then searching the database of known terrorist and decide different things about a person, before even until the end of the walking area. This would stop known terrorists or any other person from getting on a plane, dangerous and cause problems for many people.
On the same computer, you can also check out dangerous or explosive devices, people on their person or any other information that the machinery controllers cared to collect.
The Conclusion Of The
AFIS is an exciting field of science. This is a field dominated by a few companies and individuals due to the high level of technical expertise that is required to construct such a system. It is not for lazy or faint-hearted. For further studies to check out the book "automated fingerprint identification systems (AFIS) by Peter Komarinski. I remember what Mom using the say all the time, "keep your hands to Yourself!"
