Forensic Investigator Essay

During the identification phase, the user puts the finger on the same sensor, generating a new fingerprint image or template called query print. Minutiae points are carried out from the query print, and the matcher module compares the set of query minutia with the stored minutia templates or image in the enrollment database to find the number of similar minutia points. Because of variations present in finger placement and pressure applied to the sensor, the minutia points take out from the template and query fingerprints must be lined up, or submitted before matching. After line up the fingerprints, the matcher decides the number of pairs of matching minutiae-two minutiae points that have similar location and directions. The system decides the user's identity by comparing the match score to a

FBI is one of the important scientific generalist that includes extensive reference collection of files like National Vehicle Identification Number (VIN), National Motor Vehicles Certificate of Title file, etc to solve crime. Certification and accreditation are two important regulation processes that have been implementing in forensic science. During the process of investigation, FBI highly recommend not to send specimen if it takes more than 24 hrs. The Supreme Court of California in 1946 rules stated, “Finger prints are the strongest evidence to prove the identity of a person.”

In July of 1999 the fingerprint was introduced into the IAFIS. The FBI had so many fingerprints on file that in order to convict someone it would take years for them to be able to match a fingerprint. This database created a way for it to be completed faster and more efficient. The data is taken first with directly indefinable characteristics (name, social security, address, telephone number, email, biometric identifiers, photography) and then entered in the with non-indefinable characteristics (gender, race, birthdate, license number) to create personal file. The database is maintained by the FBI to keep all of the fingerprints in line. But, many agencies (federal, state, local and foreign) can use the database on order to make sure a suspect isn't linked with any other crimes and to identify the

For over a century fingerprints have been one of the most used tools of forensic science. Fingerprints have been used to identify criminals of small crimes

During investigating a crime scene there is very important databases that can help make or break a case. Some examples of certain databases they use are National Integrated Ballistic Information Network (NIBIN), The Integrated Automated Fingerprint Identification System (IAFIS), and Combined DNA Index System (CODIS). Using these certain databases can help you solve a crime more efficiently because you can find answers you need more quickly with the technology that is now provided.

The use of fingerprinting as a means of identification was born out of the need of law enforcement officials to have permanent records that could determine if a convict had been previously arrested or imprisoned. Before the advent of fingerprinting, law enforcement used a number of different methods to try to accomplish this. Ancient civilizations would tattoo or physically maim prisoners. In more recent times, daguerreotyping (that is, photographing) was used, but proved to be less than reliable, because people had the ability to dramatically alter their appearance (Skopitz). As a result, this method too, became obsolete with the discovery of fingerprinting, an absolutely infallible

Just like the license plate reader, civil societies are worried about the instant identification finger printing method employed by law enforcers in nabbing offenders. The gadget/ system which gives police an instant access to database for cross checking against the prints they have obtained from a suspect enables the officers to pick any data and history on the subject from name, date of birth, social security number any other details about the person. The Florida Department of Law Enforcement, FDLE, has employed the use of the new technology going by the name of FALCON to assist in the criminal identification process. The system is able to compare the partial and palm prints obtained from a crime scene to the fingerprints in the data bank. FALCON is also capable of pulling and

The automated Fingerprint Identification System is also known as the AFIS within the law enforcement division (FBI, 2010). This system is an important element in the criminal justice system as some of its features encompass the storing of data, encoding, and fingerprint and facial comparison through graphics and other techniques. Law officials many centuries ago in the pursuit of positively identifying someone suspected of guilt have long used fingerprints techniques. Fingerprinting is also used in branches of our government, and in the Pentagon, the authentication method of fingerprints is used permit access to specified zones inside the building. Fingerprints are an effective and very precise method of identification purposes that does not pose

“Fingerprint recognition is one of the divorce inference using the impressions made by the minute ridge formations or patterns found on the fingertips. No two people have exactly the same arrangement of the ridge patterns, and the remaining patterns of any one individual unchanged. Fingerprints infallible provide a means of personal identification. Other personal characteristics may change, but not fingerprints”. (1)

The IAFIS database came about in mid-1999.” This national, computerized system for storing, comparing, and exchanging fingerprint data in a digital format permits comparisons of fingerprints in a faster and more accurate manner.” This database is operated by Criminal Justice Information Services(CIJS). Fingerprints are collected for the most part are collected

The very first murder case in Britain regarding bludgeoned husband and wife victims, Thomas and Anne Farrows, would have been impossible to solve if not for the fingerprint evidence that implicated the Stratton brothers. Millions of cases after involving fingerprints all relied on the analysis and identification to determine guilt or innocence. ("Fingerprint evidence is used to solve a British murder case") The significance of fingerprinting is undeniable; they can successfully prove that a criminal was present at the scene of the crime or help exonerate the innocent based on the scientific and legal establishment that fingerprints are

Every time somebody touches something, they leave behind a unique signature that forever links them to that object. This link is their fingerprints, which are unique to every person, for no two people have the same set, not even family members or identical twins. Palms and toes also leave prints behind, but these are far less commonly found during crime scene investigations. Therefore, fingerprints provide an identification process that is applicable to background checks, biometric security, mass disaster identification, and most importantly, crime scene investigations. Fingerprints are so differentiated because they are made up of distinct patterns of ridges and furrows on the fingers. The ridges are the “raised” portions of the prints, and the furrows are the “recessed” portions. This perceived uniqueness has led some people to falsely accept fingerprint analysis as absolute scientific fact. Although overall fingerprints are reliable, there are definitely situations where their accuracy can come into question.
