Fingerprint recognition relies on features found in the impressions made by distinct ridges on the fingertips. There are two types of fingerprints: flat or rolled. Flat prints are an impression of only the central area of the finger pad while rolled prints capture ridges on the sides of the finger as well as the central portion between the tip and first knuckle. Fingerprint images are scanned‚ enhanced‚ and then converted into templates

Chapter I INTRODUCTION Fingerprint technology is a part of biometric system that is made to recognize special characteristics of an individual. Basically it involves an individual’s fingerprint‚ where those minute raised ridges on our volar pads are called ‘friction ridge skin’ is special from one person to another. For this reason fingerprints are able to be used as a form of personal identification as it is reliable and accurate. No one would have to remember passwords‚ PIN numbers or even

that helped us create our theories. The first piece of evidence we looked at was the fingerprints. We had prints from the victim‚ as well as other fingerprints‚ presumably from the culprit or culprits. We examined the different patterns‚ and identifying marks that can be used to determine whose fingerprints were found at the crime scene. As we studied the fingerprints‚ we discovered that one of the fingerprints contained a loop in its pattern. After further examination and consideration‚ we determined

& Fingerprint Time and Attendance Systems Biometrics access control systems use human physical traits to uniquely recognize or identify persons. The most common biometric access control system is a fingerprint reader. Using a person’s fingerprint‚ the reader is able to determine who is trying to gain access to the system. Most biometrics systems also include time and attendance logging. When a person places his or her fingerprint on the device‚ the device stores that user’s fingerprint on its

Module Four Lab Questions Lab Number One 1. Which of the three types of fingerprints was the fingerprint that you examined (loop‚ arch‚ or whorl)? Within that print‚ what minutiae did you see? 2. Compare the print of your helper with your own. Describe the similarities and differences between the two fingerprints. 3. Imagine that you are Alphonse Bertillon and you are trying to explain why you think fingerprints can be so useful to help solve crimes. What would you say to persuade them? Pretend

Discussion: In this experiment a ketone‚ 9-fluorenone is reduced to and alcohol. The are two possible ways by which this reduction can occur. One is by a catalytic hydrogenation‚ this uses a catalyst such as palladium or nickel‚ hydrogen gas‚ and heat/pressure. This can reduced an alkane to alkene. This catalytic process is preferred in industrial practices because the cost is low in the long run and more importantly there is little to no waste expense. However‚ hydrogen gas is dangerous due to

In the show‚ it may take a few seconds or a maximum of a minute to get a result back on forensics where in real life it takes much longer. Not all fingerprints are in the database‚ therefore even if you found this so called scientific evidence‚ there was no saying if you would actually find a match. The same goes for DNA samples.
