Fingerprints are detailed, difficult to alter, and permanent over the life of a person, which makes them suitable as a long-term identifier of an individual. They also can be used to identify people who are deceased in the aftermath of a crime. The recovery of fingerprints from a scene is an important part of forensics in identifying a possible suspect. Blood is often found at various types of crime scenes, such as homicide, assault, rape, robbery and burglary. Blood type can be an identifying factor to assist investigators to narrow the search for a suspect. With DNA typing technologies, an individual bloodstain can now be used to identify an individual of a crime or a suspect. Blood spatter can also be used to identify which hand a person used during a stabbing, the direction of a shot and even the distance of the shot from the victim.

In terms of classification of finger prints, the actual trace itself can be distinguished by analyzing the finger using the accepted terms for the patterns that all fingers exhibit. These include “whorls” which is the circular shape, ridges and ridge endings which are unique in almost every way and also loops which are the elongated bend shape which can originate from the left or the right of the finger. Other, more rare characteristics of the finger print is the arch which is slightly raised lines and tented arches which form a triangular looking fingerprint.

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

By the late 1800s there were two systems being used to identify criminals and fingerprints were collected as evidence in crimes. Alphonse Bertillon was an assistant clerk in the records office at the police station in Paris created a way to identify criminals. The system was sometimes called Bertillonage was first used in 1883 to identify a repeating offender. Once you’re in the system you’re in the system for life. Fingerprints are formed in the womb around 10 weeks of gestation. The secretions from your sweat glands which then leaves a small amount of oils and salts when the ridges are pressed against an object. The three types of fingerprint patterns are Arches, Whorls, and Loops. Finger prints are unique to an individual that now even identical

Finger prints today are used in a number of different ways including the prevention of forgery, identify an accident victim, verify job applicants, provide personalized access to everything from ATMs to computer networks and even phone security. But what fingerprints are useful for in forensics is that no two people have been found to have the same fingerprints as there is a one in 64 billion chance that your fingerprint will match up precisely with someone else's. Fingerprints are even more unique than the genetic material in each of our cells or, DNA as although identical twins can share parts of the same DNA they still won’t have similar finger prints. This allows police and detectives to identify each person individually from a simple process

According to Jain Anil, fingerprint-based identification is the oldest method which has been successfully used in numerous applications and though Bertillon’s anthropometry raised many valid points in forensic science, it was discarded and replaced by the fingerprint identification method after Bertillon’s death 1914.

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

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.

Biometrics technology aims at utilizing major and distinctive characteristics such as behavioral or biological, for the sake of positively indentifying people. With the help of a combination of hardware and specific identifying sets of rules, a basic human attribute, automated biometric recognition mimics to distinguish and categorize other people as individual and unique. But the challenges surrounding biometrics are great as well.

You have seen biometric technology in the films Mission: Impossible and Gattaca. The technology has also graced the covers of many weekly news magazines. But many people, even though the technology has been widely talked about for the last half decade, are still surprisingly unaware of what biometrics are and why the technology is so important for computer security and personal identification.

The obtained image is applied to a thinning algorithm and subsequent minutiae extraction. The methodology of image preprocessing and minutiae extraction is discussed. The simulations are performed in the MATLAB environment to evaluate the performance of the implemented algorithms. Results and observations of the fingerprint images are presented at the end.

The technology is many years away from development. Blood pulses on a finger can be measured by new biometric systems. This technology is currently under development. Nail bed identification is based on identifying distinct spatial arrangement beneath the fingernail. Gait recognition is another technology which is under development. This recognizes individuals by their distinctive walk and captures a sequence of images to derive and analyze motion characteristics. The technology is currently under development and its complete potential and limitations can be fully assessed. Many biometric identification systems are being developed and tested (Woodward, 2005).

The final main biometric technology used is fingerprint recognition. This is definitely the most widely used biometric technology. This type of biometric has been used for many, many years. Because of this, fingerprint recognition has been known as the most primary and accurate identification method used to identify a person. The modern fingerprint recognition is all done electronically. There are two main ways of analyzing fingerprints electronically. The first plots points on the ridges of a person’s fingers that enable the computer to compare to different fingerprints. The second method uses patterns of a fingerprint

Biometrics is a method of identifying an individual based on characteristics that they possess, typically physiological features such as a fingerprint, hand, iris, retina, face, voice, and even DNA. Some methods of biometrics security even use multiple physiological features or multimodal biometrics to provide superior security than a single form of biometrics can provide. Why are biometrics important in the field of information security? Biometrics provide a remarkable amount of security for information because biometrics are unique to each person, and thus cannot be lost, copied, or shared with another individual. This security allows for biometrics to provide a means to reliability authenticate personnel. The importance of biometrics can be further divided into the history of biometrics and why it was devised, past implementations of biometrics, current implementations of biometrics, and future implementations of biometrics.
