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).

The Fight for Freedom and Rights in Early America Essay -- People Hist

The Fight for Freedom and Rights in Early America The names and faces of those considered pioneers in the fight for rights and freedom may not be instantly recognizable, but nevertheless, they are an important part to the history of the United States of America. Throughout the history of our country, there has not just been an injustice towards black slaves, but also towards women, with both being unfairly discriminated against. It was the work of many individuals who brought the unfamiliar taste for rights for all God’s creatures to the mouths of many people. The impact of such people, including Elizabeth Cady Stanton and Frederick Douglass, towards the demand for rights for women and slaves cannot be measured. Elizabeth Cady Stanton (1815-1902) was born and raised in Johnstown, New York and was one of six children (Stanton 169). She was an incredibly gifted woman, extremely smart and intelligent and had a tongue for linguistics, as she had studied Greek and Latin. She enjoyed intellectual and stimulating conversations and became quite interested in temperance movements, abolishing slavery, and the struggle to gain rights for women. One day, after a discussion with like-minded women, she proposed a woman’s convention to discuss their situation. In July of 1848, she organized the first woman’s rights convention in the United States, known as the Seneca Falls Convention. Frederick Douglass was a slave with ambition and he became more educated than most slaves were by learning how to read. This in theory was good, but at times, did not work out to his advantage. His acumen and intelligence were characteristics that fed his yearning for knowledge and his taste for freedom. Frederick Douglass (1817-1895) was born... ...e of Elizabeth Cady Stanton or Frederick Douglass, but their impact on American history cannot be calculated. Their goals and ideas pushed through a white male dominated world and they set out to make change. They knew it would not come easily, but they knew it was something they were willing to fight forever for. It is due to their leadership, intelligence, and the strength in their hearts for the reason why they are considered two of the most important pioneers in the fight for freedom and the fight for rights for all individuals in our society.

Mice, the smartest creatures on Earth, are used by humans to conduct experiments and to gather new research. Arthur can not believe at first that these animals could are the smartest. But Slartibartfast, a native of the planet Magrathean, convinced him: How better to disguise their real natures, and how better to guide your thinking. Suddenly running down a maze the wrong way, eating the wrong bit of cheese, unexpectedly dropping dead from myxomatosis [. . .] You see, Earthman, they really are particularly clever hyperintelligent pandimensional beings.

DQ week three (a) - Essay Example There is also need to integrate several researches and form evidence out of them to strengthen one’s findings. FRONTIERS present good examples of how research findings should be synthesized and translated for the sake of producing programmatically useful information (Royle and Blythe 72). There is a need to communicate results via numerous channels to reach the same audience many times and several audiences at least once. This can include; national workshops, international conferences, and program briefs among others. Feedback should focus on description instead of judgment. Describing behavior will be a report of what took place while judgment behavior evaluates what took place in terms of wrong or right, bad or good. Evaluative language will prompt an individual to respond defensively (DiCens 38). One should observe instead of inference. Observing is seeing what can be seen or listening to one’s behavior while inference is the assumption and interpretation one makes out of seeing or hearing. One should be keen on what a person did and the reaction. Reference should be made to what an individual did rather than what is imagined of the individual, adverbs describing action should be used rather than adjectives describing qualities (DiCens 39). For instance, instead of telling one that he or she talks too much, tell him or her that your opinion in the staff meeting was
