Fingerprints are ridges on the inside and tips of a person’s finger that form patterns that only that person will have. Even though your finger print pattern can be somewhat similar to someone else’s, everyone has their own unique and special pattern. That pattern can identify who you are. These patterns do not change over the course of your life starting from when you are born. Only thing that changes is that the ridges will get larger as you grow.
In 1686 Marcello Malphigi was the first to come up with the different patterns in a person’s finger but he didn’t go into that much detail. In 1880 Henry Faulds was the first to identify a fingerprint and came to the conclusion that they are used for identification purposes. By 1888 the first book about fingerprints called “Fingerprints” was published by Sir Francis Galton and he also developed the first system of classifying fingerprints. This system was made to state that no two prints are the same. In 1901 the Henry classification system was later developed by Sir Edward Henry, and this system categorized the ridge patterns into three groups: loops, whorls, and arches. These findings led to today’s fingerprint analysis. Which is used everywhere. Fingerprinting was later introduced to prisons, the army, and widely used for identification by law enforcement.
Fingerprint analysis is a technique that compares images of prints taken to fingerprints that are already in a database. Fingerprint analysis is a strong tool in testing for identification. It is used to be able to tell who a person is. Fingerprints have been used for many years to positively identify a person. People use fingerprints for numerous things such as: time clocks at work, ids, documentations, background checks, and...

...al scanners and capacitance scanners. These scanners identify the prints by using reflective lights and electrical currents to look at the ridges. By using these scanners it helps the examiner to be able to compare the image of the fingerprint taken to the one in the database better. Computer systems are also used to analyze fingerprints because they sometimes give better results.
I have come to the conclusion that fingerprint analysis is most commonly used with law enforcement. Without this process it would make it hard for police officers and or detectives to do their job. This helps them decide on who is the suspect and close the case and it can also link suspects to other cases that have yet to be solved. Big businesses and government jobs use them as well but not as much as law enforcement. Law enforcement is the main reason why fingerprinting is so popular.
DNA is the blueprint of life. It stores our genetic information which is what is in charge of how our physical appearance will look like. 99.9% of human DNA is the same in every person yet the remaining .1% is what distinguishes each person (Noble Prize). This small percentage is enough to make each person different and it makes identifying people a lot easier when its necessary. DNA not only serves to test relationships between people it also helps in criminal cases. DNA testing in criminal cases has not been around for many years if fact it was not until the early 1990s when the use of DNA testing for criminal cases was approved and made available. By comparing the DNA of a suspect and that found in the crime scene a person can either be convicted of a crime or they can be exonerated. This method of testing gained more publicity in the 1984 case of Kirk Noble Bloodsworth a man who had been convicted of the rape and first degree murder of a nine year old girl in Maryland. His case was a milestone in the criminal justice system since it involved the use of new technology and it also raised the question of how many people had been wrongly incarcerated for a crime they did not commit.
They can trace the suspect with only a few clues within an extremely short time. They can even find out the personalities when they see someone's handwriting. They even have a private jet for Behavior Analysis Unite. When they take a case, they can fly to the location right away. They are good negotiators, too.
Another discrepancy between actual forensics and how it is portrayed in the media is the availability of information in databases. There is only a small percentage of the entire population’s fingerprints or DNA samples stored within databases such as the Integrated Automated Fingerprint Identification System (IAFIS). This makes finding a match between a DNA sample or fingerprint difficult, as a match would only be found if the person’s information was already stored within the database. If there is no match previously stored in a database, the fingerprint or DNA sample could be potentially rendered useless within a trial. Typically, in order to perform an analysis, investigators must already have a suspect in mind and request a DNA or fingerprint sample from him or her. If the suspect does not want to provide one however, the sample collected as evidence may not count as valid. The CSI effect creates an idealized image that all crimes can be solved with a hair or drop of blood, but this is not always the case in real life.
By the 19th century, the criminology research scholars have had a keen interest in biometric identification, they hope to combine physical characteristics with criminal tendencies, which resulting in a series of measuring devices, and also collected a large amount of data. Since then, the concept of measuring a person's physical characteristics are finalized, fingerprints also become the identification of international methodological standards for public security agencies. People often debate whether fingerprints have absolutely unique, and also thought that the different countries have the different standard for identifying fingerprints. So far, it is still the most widely methods of public security organs, and the process is also automated.
Being a criminal profiler is not like it is on all the television shows, but it is still an interesting and important job. Criminal profilers have been used to close many police and federal cases. They work in several homicide cases involving rape, racial killings, brutal killings, and involving serial killers. They help make it easier for the police to find the right person by examining the crime scene. Being a criminal profiler is a tough job but with hard work and dedication it is a great career choice.
The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the
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 three different main types of fingerprints are Loops, Arches, and Whorls (Jackson 1). Henry Faulds is known as the Father of Fingerprints and developing fingerprints (Jackson 1). His discovery of fingerprints has made a huge impact not only in his time but, in Modern Crime Scene Investigation (Jackson 1). Without fingerprinting, it would be very difficult to convict criminals of crimes and very hard to try to process information. Crime Scene Investigators make a huge impact in Forensic Science. We need CSI workers, without them people could only imagine what crime would be like not only in our community, but in our
Law enforcement uses several methods to solve all types of crimes. Having a variety of ways to help solve an investigation gives officials an advantage. If one method fails or isn’t helpful, there are several others they can rely on. For instance, if there are no physical witnesses to a crime, the criminal may have left a fingerprint at the crime scene. An individual’s fingerprint is unique, “no two persons have exactly the same arrangement of ridge patterns” (“Fingerprint ID”). Fingerprints of criminals and of civilians are collected and stored. Also, “People who apply for government jobs, jobs that handle confidential information, banking jobs, teaching jobs, law enforcement jobs, and any job that involves security issues can be fingerprinted” (“The First ID”). Fingerprints are processed within hours and minutes through the Integrated Automated Fingerprint ID System. This system was developed in 1991, and made it easier for different law enforcement agencies to store and share fingerprints.
Everyone in Canada should be photographed and fingerprinted because it would make it easier to catch criminals and over all make a law enforcement officer’s job less stressful. The reason for this would be that officers can identify who committed a crime by simply scanning a bank robber’s face from a surveillance camera then matching the photograph they took of him even 20 years ago (all because technology is moving so fast). This would not be an invasion of privacy because the police officers would not be using the face recognition from the photograph or fingerprints as a device to search through people’s personal lives, it would be used to identify criminals and would also help prevent crime from occurring. I.e. if people knew the government had a face recognizer and can instantly match fingerprints, many people would decide to rather live a crime free life and earn an honest way of living because they know that if the police are called to the crime, they can scan the fingerprints and find a match. The data base that holds this information would also help direct law enforcement to where the suspect lives, works, goes every week, the car he drive etc. which would help in quickly apprehending the culprit and bringing him to justice. An example of how useful fingerprinting technology is was when Jerry Watson was convicted of committing murder 30 years earlier. At the time (1978), the latent fingerprint from the crime scene could not give the police any leads. Technology kept advancing, which allowed the police force identify and test the fingerprint and after a few days, they identified the culprit to be Jerry Watson. Seeing that the idea of everyone being fingerprinted and photographed would solve and prevent crime in Canada, it would be a good idea to implement it into society.
By definition, “biometrics” (Woodward, Orlans, and Higgins, 2003) is the science of using biological properties to identify individuals; for example, fingerprints, retina scans, and voice recognition. We’ve all seen in the movies, how the heroes and the villains have used other’s fingerprints and voice patterns to get into the super, secret vault. While these ideas were fantasy many years ago, today biometrics are being used and you may not even know it.
Fingerprinting information varies in numerous ways. Each person’s fingerprints are different in someway (Unique). The technical term is actually “DNA fingerprinting” because us as a person obviously cant just take a look at a fingerprint and see the difference; we must analyze the actual DNA behind it. Sometimes a miss concept of most people is, that fingerprints stay perfectly fresh for extended periods of time. Partial fingerprints and even degraded full fingerprints can turn up to be useless sometimes. Fingerprints are not admissible if they are 99.9% sure, they must be 100% or a Forensics lab will not support them. DNA Fingerprinting, and the fingerprints that are at the tips of your actual fingers are two different things. The ones we a...
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...
Although these elements are extremely important there are other elements to criminal profiling that help build the profile.
This can make the process of narrowing down suspects much easier. Databases of citizens’ personal information can also be found. Therefore a person could be found easily when needed for questioning.
