Potential Use Of Biometrics In The Criminal Justice Field

796 Words4 Pages

To begin, biometrics are considered unique physical characteristics, such as DNA, palm prints, fingerprints and even facial recognition, that can be used in an automated form to recognize a person. In sum, biometrics are biological measurements (“Next Generation Identification”). In the criminal justice field, biometrics are used often to identify suspects. Examples of this type of technology include Advanced Fingerprint Identification Technology (AFIT), and the Integrated Automated Fingerprint Identification System (IAFIS). Biometrics are important in today’s world and with the rapid advancement of technology, we can expect the use of them to increase in the upcoming years. This paper focuses on the potential uses for biometrics, and the …show more content…

Some of the examples that are potential uses for biometrics are airport security, building access, cars, blood banks, and school. It can be used with airport security because when passengers look into a camera, it scans your eyes and iris. Once that camera scans you that goes into a database and it collects information about. That’s why in airports it’s very easy for securities to recognize who you are. In building’s, it uses fingerprints to let you enter building’s and it recognizes who you are. In cars, you have voice recognitions, Bluetooth and other technology in a vehicle that can run or play. Blood banks uses iris recognitions and fingerprints for patients who donate blood and keep information about them. It can be used in school by having face recognitions for students, stuff and recognizable who belong in that school or who enters the building (“5 Ways Biometric Technology is Used in Everyday …show more content…

Many systems in today’s society require us to remember multiple passwords, for multiple things. With biometrics, the need to remember those tedious passwords, along with changing them every so often is eliminated. Biometric data on an individual will not be the same as any other person, and will not make extreme changes. It makes it that much easier to scan an individual’s iris and use it for the remainder of time, unless the system becomes breached somehow. Security systems that use biometrics can be established quickly and with ease as it only takes a few moments to scan a fingerprint or an eye. In areas where individuals are pressed for time, biometrics presents an increase in convenience because one does not have to input their complex password in, but rather just have their fingerprint or eye scanned. If a security system is equipped with multiple biometric capabilities, it allows for a two-layer authentication before being allowed access. For example, the system could require your fingerprints along with a facial recognition, or a scan of your

People in the military are fingerprinted, and it is also required for many other occupations and organizations. When it comes time to match a fingerprint with an individual, it is quite easy due to the wide library of fingerprints the FBI maintains. This library contains the fingerprints of “more than 10%” of the U.S. population. For smaller cases, law enforcement are given access to this library directly from a police station ("Forensic Science" [Gale] 18).

Fingerprint analysis is a method of identifying individuals based on the unique patterns of ridges and valleys on their fingertips. In Dahmer's case, investigators were able to use fingerprints to identify the remains of his victims and link them to specific crime scenes. Fingerprint analysis has been used in forensic investigations for over a century and is considered to be a highly reliable method of identification. It is based on the fact that no two individuals have the same fingerprint patterns and that these patterns remain consistent throughout a person's life. In Dahmer's case, fingerprint analysis was used to identify the remains of several of his victims, including Anthony Sears and Ernest Miller.

The Richard Ramirez "Night Stalker" case was one of the first major cases to use automated fingerprinting technology (Frese, 2011). Today, the fingerprinting database gives various probable identifications, then a trained fingerprint expert must compare the prints to find a likely identification. Considering that Ramirez's prints were found on the mirror of a stolen vehicle we can conclude that his fingerprints were two-dimensional, therefore the prints are termed as latent or residue prints. The authorities at the crime scene power-dusted his prints considering that is the best physical method for collecting fingerprints. Once analyzed using the ACE-V (analysis, comparison, evaluation and verification) method, the fingerprint expert was able to identify them as belonging to Ramirez.

The D-Day invasion of June 6, 1944, was one of the most significant events in World War II. Codenamed “Operation Overlord", the invasion was a coordinated effort between Allied forces to liberate German-occupied France and ultimately bring an end to the war in Europe. D-Day was known as the largest assault ever carried out. The success of the invasion relied heavily on technological advancements that enabled the Allies to overcome the formidable German defenses, such as amphibious tanks, water-landing crafts, and artillery and air raids. Amphibious tanks were one of the most critical technological advancements that played a significant role in the D-Day invasion.

There is powerful verification that fingerprints aren’t foolproof. In “ Forensic Science: Evidence, Clues, and Investigation” by Andrea Campbell, she gives a strong explanation of how forensic science plays a vital role in solving criminal cases. Campbell has shown that forensic evidence is unquestionably the most dominant type of evidence to present at a trial. In the same way, “...unless the criminals take something away from the crime scene, hard evidence does not leave.

Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).

Invasive species is a majority factor to the loss of biodiversity across the United States. The National Wildlife Federation (NWF) concluded in a study of invasive species that they are responsible for the decline or extinction of roughly 42% of endangered or threatened species in the United States. Invasive species is an organism that is not native to a location or ecosystem and offer the potential to cause harm to not only the environment, but also to human health and the local economy. The introduction of these invasive species into an environment has had significant impacts on the conditions in which native species survive and their ability to adapt to counter the new threat. Invasive species compete with native species for food and resources

On the complement, face identification is a 1: N problem. It is used compares a query face image against all image templates in a face database. Face recognition has distinct advantages over biometrics systems using finger print/palm print and iris, because of its non-contact process. It is mainly used in security systems. Face images can be captured from a distance without touching the person and the identification does not require interacting with the person.
