1. Karley Biometrics
We strive to bring you a high- quality product that will increase your productivity and the security of our nation.

2. How Biometric Works
Enrollment: the first time you use the software, it catalogues you based on a serial number and records your specific trait.
Storage: your trait is not stored as an image, but as a code that the software translates from your data.
Comparison: the next time you use the software, it scans your trait and compares it to the code, then either accepts or rejects your admission.

3. Your Personalized System
Step one: fingerprint recognition
This software recognizes minutiae in the ridges on the finger tip, which vary widely from person to person.
Our finger print scanners are 98% accurate.
In 2002 a Japanese researcher, Tsutomu Matsumoto, discovered several ways to create a fake fingerprint out of gelatin, but when used in conjunction with our other products, fingerprint recognition is virtually uncrackable.

5. Your Personalized System
Step two: Iris scanning
This software locates various reference points in the eye and analyzes them, comparing them to your pre- recorded code.
The iris is even more unique than the fingerprint, with more than 200 points of comparison. This makes it very accurate.
Iris scanners have limited accuracy with ethnic groups that have very dark eyes because it is hard to tell where the iris ends and pupil begins.
It has been found that colored contacts and drugs can effect the scan. It is very unlikely that it would misidentify someone though.

7. Your Personalized System
Step three: signature verification
This software analyzes not only the physical characteristics but also the speed, pressure, and rhythm of the writing.
With this type of analysis, even a copy of someone’s signature that was written over would probably not be accepted.
The intense nature of the system and its analysis makes it very accurate.

9. Beating The System
As previously discussed, there are ways that each individual biometric system could be beat. That is not an issue though, because the way in which we work prevents anyone being able to break the system. The combination of the three systems makes it pretty much impossible.

10. Success Story
Back in August 2010 in a government security office in Chicago there was a huge security issue at hand. Someone had been moving and stealing files out of a top secret corridor, but they culprit could not be found or tracked. They had a group come in and install new password locks. That did not help at all and cameras were not doing the trick either. Then, they decided to call Karley Biometrics. With the use of our finger print scanner, handwriting analyzer, and iris scanner, we were able to expose the criminal as well as prevent any future break in or security breaches. Our success rate is 100% !

11. Privacy issues
Many people feel as if their privacy is being violated with biometric systems. Or they don’t believe in it due to cultural reasons.
The main fear is that they will be able to be tracked by a database that holds all the info from the scans. That is not the case in reality though. The technology is not yet advanced enough to store all the information for people all over the world. The data is also translated into codes rather than “by name”, so that makes it less of an issue. To add to all of that, many systems are not yet all compatible with each other over different systems. So while some people are still weary of the idea, it is soon to be inevitably part of our lives.
