Alphonse Bertillon, a Parisian anthropologist, and police desk clerk developed a method for identifying criminals that became known as the Bertillonage technique. Bertillonage was a system created in the 1800’s by which measurements of the body are taken for classification and comparison purposes (Pike, n.d.). His technique charted the length of a fingerprint, the fingerprint’s pattern, a person’s sex, and even whether someone smokes or not Although the Bertillonage technique is no longer used based off of insignificant inaccuracy identification, the technique birthed the idea of fingerprinting.
Fingerprints are mapped through tiny ridges, valleys, and whorls on the tip of each finger. No two people have the same fingerprints because they are

Fingerprints obtain more uniqueness than DNA based off of each person’s genetic material. So what about identical twins? Although identical twins may have the same DNA, they will not have the same exact fingerprints. This form of biometrics is ideal for biometric systems because they are easy to classify and sort, without any change in appearance or structure. If fingerprints are so unique and refined, how can they be recorded accurately? Fingerprint scanning has already been implemented into business to effectively enhance security and authentications. When scanning a fingerprint, a scanner has to have a pre-saved image of the authorized finger to compare images in a linked database to allow access. In order to allay privacy concerns, however, fingerprint scanners do not store actual fingerprint images. Instead unique characteristics of the fingerprint are analyzed and stored as an encrypted mathematical representation (Ballard, 2016). Businesses are hoping to safeguard their sensitive data by using this form biometrics as a viable option because of the several benefits and low costs. This is a easy to use system with cheap equipment that generally requires low power consumption. However, the disadvantage is that if the surface of the finger is damaged or contains any marks, the identification becomes increasingly difficult. Fingerprint security systems are already
In 1892 the Alphonse method was introduced. introduced by which the police would measure the suspects parts of the body on the assumption that no two humans would be the same. The
Trace evidence was first discovered by Edmond Locard. Edmond Locard was born in 1877, and founded the Institute of Lyon’s Institute of Criminalistics. He is also known for advancing the science of fingerprints. In 1910 he was authorized to start a small forensic laboratory in the Palais de Justice which he directed until 1951.While there he worked on criminal identification methods including poroscopy- the microscopic examination of fingerprints; analyses of body fluids, hair and skin; and graphometry or handwriting analysis. He is the man responsible for coming up with the theory that when two objects come in contact with each other they leave some kind of material matter behind. This theory was later called Locard’s Exchange Principle. The idea is that the evidence can be used to associate objects, individuals or locations with one another." A person typically loses about 100 hairs a day. These hairs may be of evidentiary value to show contact between two people. With an adequate hair standard, a trace chemist will be able to microscopically compare a...

(f) Spoof attacks and Template security: Spoof attack refers to the deliberate attempt to manipulate one’s biometric template in order to avoid recognition, or generate biometric artifacts in order to take someone’s identity. And still biometric systems are susceptible to attacked in a number of ways (Ratha et al., 2001). For example, a fingerprint recognition system can be circumvented by using fake or spoof fingers (Nandakumar et al., 2007, Nandakumar et al., 2007a). Behavioral traits like voice (Eriksson et al., 1997) and signature (Harrison et al., 1981) are more susceptible to such attacks than physiological traits. Security of biometric templates is also another critical issues in biometric systems. The stolen biometric template can be used to gain unauthorized access to the system (Adler, 2003, Cappelli et al., 2007, Ross et al., 2007).
Biometric and encryption sounds are not too fresh, for most users, any of each technology alone is not enough to make you feel excitement. However, If we develop a new study or a new technology, which combine the biometrics and encryption. We can find that the technology combining these two techniques are very amazing.
DNA fingerprinting, or sometimes known as DNA typing, is isolating and developing images of sequences of DNA to evaluate the DNA in an individual’s cells. DNA fingerprinting today is used for many different things in many different areas of science. In forensic science, DNA typing can determine which person did which crime by using blood or skin left at a crime scene. In medical science, patients can find out who their siblings, parents, or children are by using DNA fingerprinting (webmd).
Forensic genetics has other applications . The " fingerprint " DNA represents a valuable tool for forensic science . As is the case with an ordinary fingerprint genetic fingerprint is unique to each individual (except identical twins ) . The determination involves the observation of specific DNA sequences which can be obtained from extremely small tissue samples , hair, blood or eventually left at the scene . As Fifty microliters of blood, semen or five microliters of ten roots of hairs are enough , and nozzles secretions and cells from the fetus . In addition to its use in the capture of criminals , especially rapists , the genetic fingerprints can be used to establish family relationships . People involved in the conservation of species use them to be sure that captive breeding is among individuals who do not belong to the same family .
The costs of implementing biometrics into security, specifically passports, are enormous. In many instances, cost is much higher than traditional forms of security such as passwords and personal identification numbers.10 Biometrics also puts users...
Biometrics is described as the use of human physical features to verify identity and has been in use since the beginning of recorded history. Only recently, biometrics has been used in today’s high-tech society for the prevention of identity theft. In this paper, we will be understanding biometrics, exploring the history of biometrics, examples of today’s current technology and where biometrics are expected to go in the future.
The Automated Fingerprint Identification System or AFIS is a biometric identification technique that utilizes computerized imaging technology to obtain, store, and analyze fingerprint data. The AFIS was initially utilized by the FBI in criminal cases. Recently, it has been utilized for general identification and fraud prevention. This essay will summarize the case, State v. Keith and briefly explain the purposes and impediments of computerized fingerprint systems.
In 1893, Francis Galton introduced a remarkable new way to identify people ("Fingerprinting" pg 1 par 3). His observation that each individual has a unique set of fingerprints revolutionized the world of forensics. Soon, all investigators had adapted the idea to use fingerprints as a form of identification. Unfortunately, over the course of the past century, criminals have adapted to this technique and seldom leave their incriminating marks at the crime scene. Forensics specialists were in need of a new way to identify criminals, and DNA provided the answer. When it comes to genetic material, it is virtually impossible for a criminal to leave a crime scene "clean." Whether it is a hair, flakes of skin, or a fragment of fingernail, if it contains genetic material then it has potential to incriminate. However, there are still concerns regarding DNA fingerprinting. What are the implications of using these tests in a courtroom scenario? What happens when DNA tests go awry? It is debatable whether or not DNA fingerprinting has a place in America's court systems.
Have you ever wondered who aided in the discovery of identifying the criminals of today? A French man by the name of Alphonse Bertillon who was born on April 24, 1853, is to be acknowledged for his great work. Bertillon was the son of a man named Lois Adolphe Bertillon who was a physician and statistician. Although Bertillon has greatly contributed his techniques to science, he faced some difficulties before his discoveries. Bertillon dropped out of school and because of this, his father sent him to Great Britain for a while and then returning home. After returning to France, he was inducted into the army until 1879. Following his retirement from service, he took a job as a clerk with the Paris Prefecture of Police. While working at this police station, not only would Bertillon be a desk clerk jotting down information on daily criminals, but he would become a valuable part of forensic science. This would be the start of him developing his techniques into
Fingerprint usage dates back to the 1800s. Sir William Herschel used the prints as signatures on civil contracts, before they were found useful towards crimes (History of Fingerprints Timeline, 2012). A British surgeon, Dr. Henry Faulds, wrote about using fingerprints for personal identification. He first looked at prints on clay pottery and studied the ridges and patterns that they had made in the clay. In 1891, Juan Vucetich suggested to start fingerprinting criminals to keep the prints on record. The following year, Vucetich identified a print from a woman who killed her two sons. Investigators found her print and were able to correctly match her identity. Charles Darwin’s cousin, Sir Francis Galton, wrote and published the first book about fingerprints. He wrote about how every individual has a unique print by the certain traits of each fingerprint (History of Fingerprints, 2012). The popularity of fingerprints grew greatly in the United States in the early 1900s. Police departments and the FBI began to use the...
1940). Fingerprints are formed and developed inside of the womb due to certain types of pressures that are put on a baby’s hand when forming (O'Neill, M. 1940). Fingerprints are very unique and no two people have the same or alike fingerprints not even identical twins (Polson, C.1951). There are three main types of fingerprints (Polson, C. 1951). Theses fingerprints are called loops, arches, and whorls. Fingerprints can be found on any type of solid surface. Most finger prints that are found at a crime scene are latent prints there are other types of finger prints that can also be found at a crime scene to. Latent prints are not noticeable to the bare eye. In order to clearly see latent fingerprints you have to use things like magnetic fingerprint powder or alternate light sources. Fingerprints offer a dependable means of a particular proof of
“The term -information security- means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction” (United States Code, 2008). In order to ensure the identity of who is trying to access the information, the concept of “Biometric Technology” has been developed in the last years. This essay will start explaining this concept and the characteristics of its development through the time. Then, the essay will offer a brief explanation of biometric systems operation and a description of different biometric systems developed until now. Finally, this research analyzes the current and future applications and the issues that surround it.
