Fingerprint

An imperative aspect in any criminal investigation is obtaining and identifying fingerprints as they are considered one of the most valuable pieces of biological evidence. Fingerprinting is a form of biometrics, which is a science that uses the physical characteristics of individuals in order to identify them (Watson, 2014). Ultimately, fingerprints consist of an arrangement of creases known as fraction ridges and they essentially comprise of pores. These pores are attached to the skins sweat or eccrine glands (Langenburg, 2014). Fingerprints are classified into three different categories which are commonly referred to as either patent, latent or impressed prints. Latent prints are created through the eccrine glands that produce amino acids,…

Fingerprints have been widely used throughout the world as means of identification for forensic purposes. Forensic experts have extensively relied on premises that fingerprint characteristics are highly discriminatory and immutable amongst the general population (Haber and Haber, 2008). Fingerprint formation is induced by the stresses and strains experienced by the fetus in utero, which are random and infinite, it is likely that they subsequently produce a random, infinite variety of friction…

When it comes to finding fingerprints, it is best to look in numerous locations around the home. There were ten different fingerprints found in the search, to include complete and non-complete prints. Many different items were used for finding prints, for instance the oven, refrigerator, kitchen counter, toilet button, bathroom door, mirror, television, car door, computer, and the iron. Almost all of the prints were pulled from the house except for the car door. The car door prints were…

Fingerprint Development Techniques Fingerprint development techniques are vital in crime scene analysis, personal identification purposes, and forensic research. There are three different types of fingerprints that are known: patent prints, plastic prints, and latent prints. Patent prints are common and the easiest to locate because they are visible to the naked eye, while plastic prints are also easy to locate, but far less commonly found than patent prints. Latent prints are the most common…

Unit 4 Forensics Question # 2: Briefly describe how the Automated Fingerprint Identification System (AFIS) creates a fingerprint image. What characteristics of the fingerprint does the AFIS record for comparison? With the advances of computer technology in U.S. Police agencies during the 20th century, it was only natural that what was once a labor intensive and cumbersome system, such as the filing and storage of individual fingerprint records, would become simplified by the…

Optical scanners record images of the varying characteristics of individual's fingerprints. Electronic fingerprint scans are extremely accurate 95 to 98 percent of the time. However accuracy can vary between genders, race, and chemical residue on the fingers. Fingerprints are difficult to beat, however it has been done. A Japanese researcher discovered ways to create fake fingerprints out of gelatin and therefore hacked the system. 2.Voice: Voice identification works by taking the rhythm,…

To accomplish functions, such as unlocking car doors, speech recognition would allow the machine to "Understand" several commands, discarding the need to push a button on a key fob. Automaker could soon fit cars with equipment that could make this alternative to car keys a reality. Instead of turning the key into the ignition switch, you'll simply command your car to "Start the engine." How cool would that be? Fingerprint Identification In essence, a technology replacing the key fob should be…

Fingerprints can help identify suspects, prove a person innocent, and help build cases in court. In most television crime shows, it is portrayed that as soon as a print gets put into the system it takes a matter of seconds and maybe a minute before a single sure result pops up on the screen with the face of the man or woman to whom the print belongs. However, this is not the case. Before a fingerprint can even get tested and verified there are a series of steps that have to be followed through…
