Biometric Identification

Biometric Identification BIOMETRIC IDENTIFICATION Introduction The escalating threat of global terrorism and narcoterrorism in the twenty-first century has generated massive changes in the identification of suspected criminals. One of the technological highlights in this regard has been biometric identification. Biometrics refers to the science of identifying human being by analyzing biological traits or physical characteristics (Bolle, 2004). This paper describes the most widely-used forms of biometric identification and presents the advantages and disadvantages of each. Advantages and Disadvantages of Biometric Systems Biometric identification is an automated method used to recognize a person based on behavioral or physiological characteristics (Tipton Krause, 2004). Behavioral characteristics include voice or handwriting. Physiological characteristics include fingerprint, iris, or hand geometry. 1. Fingerprint analysis The most commonly known biometric system is a the fingerprint analysis (Bolle, 2004). The principle here is that each individuals set of fingerprints is unique. This method requires a user to place his or her finger onto a reader. The persons fingerprint is scanned and sent to a database where it will be compared, identified, and verified. Fingerprint technology is widely used today in law enforcement, banking, and in merchandising. The biggest strength of this method is its high accuracy and low incidence of false acceptance and its low cost. However, fingerprint technology is said to have a high false rejection rate (where valid users are incorrectly rejected access). Sometimes, the technology does not recognize accurately in case of hand trauma, age, or disease. 2. Hand geometry The hand geometry identification method is the second most commonly used biometric tool (Jain, Ross, Pradhakar, 2004). Basically, it analyzes finger length and the edge of a hand. Hand biometric requires a person to place his or her hand on the device which has pegs to lay the hand on. When the hand is put properly in place, the device scans and checks the database for identification or verification. While the hand biometric device is easy to integrate, use, and can even work despite dirty hands, the technology is expensive, has low accuracy level, cannot read when hand is injured or has suffered from trauma, or when a person has arthritis. 3. Retina technology The concept is that it is practically impossible to counterfeit a human retina. The scanner analyzes capillary vessels situate in the back of the eye. Retina biometrics requires the person to place his or her eye close to a scanner and as the device scans, to focus on a specific point while being still (Jain, Ross, Pradhakar, 2004). The process takes 10-15 minutes. Retina technology has a very high accuracy rate. However, it is a sensitive process, expensive, and quite uncomfortable for those who wear glasses. 4. Voice technology Voice biometrics analyzes the pitch or tone of a persons voice. Voice biometrics fall into two categories: voice recognition and speech recognition. Voice recognition analyzes quality of the voice while speech recognition interprets what a person says (Jain, Ross, Pradhakar, 2004). The advantages of this system is that is it non-invasive and not susceptible to error due to a cold. However, its accuracy may be compromised with the presence of acoustics in the room and increased age. Conclusion Biometric identification includes methods such as fingerprint technology, hand geometry, retina analysis, and voice recognition. Although biometric identification is undeniably cutting edge technology, there are disadvantages present that is inherent with any modern technological systems. References Bolle, R. (2004).

Half the Sky Documentary Evaluation

Half the Sky is a movie that discusses the oppression of women around the world. It brings to light the issues that, even in today's society, are still occurring. Women, young adults, and children everywhere in the world are becoming victims to abuse, rape, and being deprived of getting an education. This film documents Nikolas Kristof going around the world with the help of well known people in America to show some of the issues and some organizations that are working to change the way society views women and children. Early in the documentary a shocking statistic was given. It stated that around 60 million to 100 million females are currently missing out of the population. Where are all of these women going, and how are we letting this happen in today's societies? Females all around the world are becoming victims of genital mutilation, sex trafficking, rape, and abuse. Half the Sky is shedding light into some of the cultures around the world where this is a norm, and is trying to promote awareness. It discusses the reasons why these events are still taking place in current cultures, and what we can do about it to change the way people respond to these events. Some of the issues addressed in the movie Half the Sky are talking about women being oppressed in current societies. Women are constantly being put through human trafficking, violence, are being undereducated, and catching a ton of diseases from being raped. The people in this movie are trying to look at the issues of women not being treating equally and having the same rights as men in the 21st century. One of the main reasons this is happening is because men are never even caught, and when they are most of the time are shown no consequences. Another issue that first brought these issues in countries to light was that in China many females have gone missing due to the fact that it is more accepted to have a male born into your family, not a female. Children, primarily females, are being sold at shockingly young ages to brothels and are forced to be sex slaves. In so many countries it has become a norm for men to abuse women and use them as sex slaves. There are a few reasons there has been little progress made in changing the ways some cultures view women. One reason there has been no progress is because of the lack of punishment towards those causing the abuse. An example of this from Half the Sky is when they went into Sierra-Leone. There was a case where a teenage girl told her parents about her being raped by a relative, and they decided to press charges. After the man was captured, arrested, and placed in jail the family then became almost shunned by the community. After all this occurred the father in the family kicked the wife and child out. They said it was because the child had caused â€Å"shame† upon the family. Then the child forgave the man who had raped her, and many others, and he was released free; thus, causing the cycle to begin all over again. There is a huge lack of police forces investigating crimes, and men actually having consequences to their actions. A hard problem to solve is how we can fix these problems and change the way so many people feel about women. It's a slow and grueling process, but eventually if everybody does there part we can make a difference and create equality for all women. In every culture there's at least one organization out there trying to change the way women and children are treated in their society. The greatest challenge is when you have outsiders coming into a community to talk about these issues. Many people within a culture are not going to listen to an outsider, so we really need people within the communities to help change the way that society views the way their females are treated. We need people within the culture to empower others in that society to speak up and gain more followers. Secondly, we need to train societies to prosecute and investigate these crimes more thoroughly. If these countries don't have a strong justice system no changes can be made when those committing the crime don't see it as a crime. Thirdly, we need to educate children. Girls are likely to drop out of school at an age of fourteen or before to work for their family, whereas boys are likely to drop out at sixteen. Building an educated generation will help because then they can get a career and will not be caught in poverty like so many generations before them. Lastly, we need to bring all of these issues to light in countries that can help. We need more Americans to become aware of these issues, and reach out to help make them better. Nikolas Kristof said in Half the Sky, † Once people pay attention, that's the first step towards a solution. † All of this relates to sociology in many ways. One of the main ways it relates is because you see how something so looked down upon in one culture can be so socially acceptable in another culture. When somebody is accused and prosecuted for rape in America they are put in jail for a long time, and receive consequences for their actions. If you go to say Sierra-Leone, or Cambodia the person accused of rape will almost 100% of the time walk away with no consequences. It's all a matter of perspective and your culture you live in. Everybody needs to learn to be more culturally aware, and learn to help other cultures that aren't quite were we think they should be. Sociology is also related to Half the Sky because of the idea that it chases after women and children alone being oppressed. All in all, societies are all different in one way or another. Sociology helps us to understand the reasons people may act one way opposed to another, and how we can all work together to make a difference.

Police Brutality And Its Effects On American Culture

Part One: Topic and Discipline The focus of my research is on police brutality, specifically on the various components of excessive force and what aspects of American culture allow it to continue. This topic is multidisciplinary, and fits within the bounds of sociology, African American studies, criminal justice, law, and public policy. There are multiple factors which influence police brutality, including but not limited to, location, segregation, community accountability, demographics, and current events. The research used within this paper all attempt to answer one or more of the aforesaid factors. The ultimate goal of this paper is to determine the overall impacts of all aspects of police brutality. Part Two: Discussion Five†¦show more content†¦Lastly, Seabrook and Wyatt-Nichol’s study demonstrates the evolution of legalized and socialized discrimination against black members of society. Police Use of Excessive Force in Minority Communities: A Test of the Minority Threat, Place, and Community Accountability Hypotheses is original research, as few analyses focus on the impact of place and urban segregation. The study was primarily data-based, making conclusions off of statistics pulled from the sustained excessive force complaints. The authors’ thesis is that coercive methods of policing are used against minorities, depending on multiple factors that are divided into hypotheses. The Minority Threat Hypothesis states that there is a positive relationship between coercive use of force and minority populations, with the amount of coercive force increasing as a minority’s population in a city does. This idea is psychological in nature, drawing from the idea that, due to implicit bias and criminal stereotypes, that minorities pose a greater threat against the officer than a white citizen. With greater segregation comes a greater perception of threat, especially if there is a higher crime rate in the more densely minority populated area. The second hypothesis, involving the concept of place, theorizes that minorities who are segregated within a city become primary targets of police abuse.
