Fingerprints Fingerprint is an impression of marking something superficial by the last joint of the thumb or other finger(s). Fingerprint identification is one of the most distinguished biometrics. It has been used for so many years for its efficiency and reliability. This type of identification is used by law enforcement and immigration. FBI (2013). Fingerprints helps to see if the suspect’s has been arrested or had any other convictions before. It also helps to recognize missing people, amnesia victims, and unknown dead people if they are in the criminal files. Michal Lyman (2014) A fingerprint looks like series of dark lines that symbolize the high, topping portion of the friction ridge skin, while the valleys between these ridges looks like white space and are the low, narrow portion of the friction ridge skin. FBI (2013) Fingerprints was publically used for first time in 1858 by Sir William Herschel who was a British chief administrative officer for the Hooghly district, Bengal, India. In 1877, he asked permission to his bosses to identify prisoners by using fingerprints. United States recognized the used of fingerprint for the first time in 1882, by Gilbert Thompson. In 1903, New York State prison system used this method of identification for criminals. After this, fingerprints was stablished in all U.S. There are two types of prints. One is the Latent or Patent Fingerprint. This one is invisible. It is created by oil and grease make by the body, and perspiration or dirt, when it has been touched. The only way to see it, is by using special equipment and chemicals. The other one is visible. This type is made when someone who has been exposed to blood, flour, ink or oil touches a clean surface and leave his/her prints on it. Michel Lyman (2014) The main reason of developing latent fingerprints imprint is to make the print visible, so it can be...

Forensics Finger Prints

...The three types of fingerprints that investigators may find at a crime scene are patent prints, plastic prints, and latent prints. Patent prints are visible prints that occur when a foreign substance on the skin of a person’s finger comes in direct contact with the smooth surface on another object. These prints are visible to the naked eye and typically occur when particles stick to the ridges of the fingers and are easily identifiable when left on an object. Plastic prints are those that occur when a finger leaves an indentation on a soft pliable surface. No enhancement is required in order to view these prints due to the impression that a finger leaves on the surface. Latent prints are impressions left by a finger that have secreted on a surface and are typically invisible to the naked eye. These prints are usually the result of perspiration from sweat pores in the ridges of fingerprints. IAFIS is a fingerprint scanning system that stands for...

...The world we live in is ever changing, with technology at everyone’s finger tips how can we keep one step ahead in our classrooms to engage our pupils in development issues that were once only found in print texts. Our pupils live in a media age, where technology is built into their lives, the days of waiting for a weekly magazine for the latest news has all but died with a click of button they have access to a wealth of information from varying sources be it bias or unbiased that is for the reader to decide. As a teacher it is becoming increasingly difficult to distract pupils from the latest celebrity gossip to highlight real world issues of race, poverty, sexuality, exploitation, etc., the pupils of today are uninterested in reading about these issues in text books so a new approach needs to be taken to open their eyes. The use of media texts in delivering development education issues to our cinematographic teenagers is the direction we need to head in. The type of media text used is a choice that has to be made by the teacher when highlighting these issues, the question remains should one use documentaries or blockbuster movies; documentaries by their nature are very factual, complex, have real life images and settings and can be difficult to watch; blockbuster movies on the other hand are produced for entertainment value, they must appeal to the cinema going public, must conform to western norms and expectations, in which direction should one head....

...When seen under magnifying glass our finger tips reveal ridges and circular patterns on the skin. These patterns or prints are marked before you take birth and are with you for the rest of your life. One of the most important characteristics of these fingerprints is that no two people can have identical fingerprints and hence they are used for identifying a person as evidence. Although the finger prints of every individual are different, they follow certain patterns. These fingerprint patterns are of three main types: Arches, loops, whorls. Around 5% of fingerprint patterns found are Arches. In this type the ridges are seen running from one end to other with no backward turn. Usually in an Arch pattern, delta is not found. But if a delta is present, the re-curving ridge is never seen interfering between the delta and the core...

...The print was simply used to frighten him out of all thought of repudiating him signature (The History of Fingerprints). As Hershel s fingerprint collection grew, he began to note that the linked impressions could prove or disprove identity. During the 1870 s, Dr. Henry Faulds, a British Surgeon of Tsukiji Hospital in Japan, studied skin furrows after taking notice of finger marks on prehistoric pottery. He then devised a method of classification. Mr. Faulds passed on an explanation of his classification system, along with samples of the forms he had design for recording inked impressions, to Charles Darwin. However, because of Mr. Darwin s old age and ill health, he informed Faulds that he would pass the material on to his cousin Francis Galton. Sir Francis Galton, a British anthropologist, published a book called Fingerprints. The book included the first classification system for fingerprints can be identified. Galton identified the characteristics by which fingerprints can be identified. These same characteristics are in use today and are often referred to as Galton s Details. In 1892, Argentine Police Officer, Juan Vucetich, made the first criminal fingerprint identification. He was able to identify a woman who murdered her two sons because he found a bloody fingerprint that was left on the door and was able to match the print to the woman....

...No 2 humans have the same finger, palm or footprint. These parts of the human body have ridges that are constantly broken up by endings or forks; these are called characteristics ( Every person has unique distributions of the characteristics that build up in womb and throughout life in general, these characteristics stay the same for a time after death too so it makes identifying a body possible People have often tried to alter their fingerprints with different methods like cutting their fingerprints, burning the skin with acid but that doesn’t work because, superficial skin damage is repaired by the body so the same ridges come back with the new skin that forms Fingerprints are formed by our skin and our skin is made out of two layers, dermis and epidermis. The epidermis is a thin layer and it is a protective cover of the dermis which is the thicker layer of skin that contains sweat and sebaceous glands ( Now a sweat gland consists of salt, water and urea and the sebaceous gland releases oils on the skin surface When we come in contact with something, we leave a mark because of the products that are produced by the glands, resulting in a fingerprint mark When our fingers are...

Fingerprinting Forensics

...Fingerprinting Forensics Fingerprints are one of the most important things that link a suspect with a crime scene. Colin Beavan says, “Every human being carries with him his cradle to his grave certain physical marks which do not change their character, and by which he can always be identified - and that without shade of doubt or question. These marks are his signature, his physiological autograph, so to speak, and his autograph can not be counterfeited, nor can he disguise it or hide it away, nor can it become illegible by the wear and mutations of time. This signature is not his face- age can change that beyond recognition; it is not his hair, for that can fall out; it is not his height, for duplicates of that exist; it is not his form, for duplicates of that exist also, whereas this signature is this man’s very own- there is no duplicate of it among the swarming populations of the globe. This autograph consists of the delicate lines or corrugations with which Nature marks the insides of the hands and the soles of the feet” (Beavan 1). “A fingerprint expert can tell apart the marks of two digits more easily than he can differentiate two people’s faces “(Beavan 11). Fingerprints play a crucial role in criminal detection because they are unique, have a long history, and have many uses. To begin, Fingerprints are unique when it comes to crime detection. No two people have been found to have the same fingerprints—they are totally unique. There’s a one in a 64 billion chance......

Keywords Biometric systems, technique, face, Iris, finger, lips, voice. 1. Introduction "Biometrics" implies "life measurement" however the term associated with the utilization of unique physiological characteristics to distinguish an individual. It’s a new way to verify authenticity. Biometrics utilizes biological characteristics or behavioral features to recognize an individual. In real a Biometrics system is a pattern identification system that uses various patterns such as iris patterns, retina design and biological characteristics like fingerprints, facial geometry, voice recognition and hand recognition and so forth. Biometric recognition system provides possibility to verify one’s identity simply by determining “who these people are” instead of “what these people possess or may be remembered” [4]. The very fact that makes it really interesting is that the various security codes like the security passwords and the PIN number could be interchanged among people but the physical traits cannot be. The principle use of Biometric security is to change the existing password 2. Biometric Techniques Jain et al. describe four operations stages of a uni-modal biometric recognition system [1]: ...

Anatomy of Fingerprints

...The verse states “Yes, we are able to put together in perfect order the very tips of his fingers.” (Azimi, 2013) Formation of fingerprints Fingerprint is an impression made by the papillary ridges on the ends of the fingers. It afford an infallible means of personal identification, because the ridge arrangement on every finger of every human being is unique and does not alter with growth or age. It also serve to reveal an individual’s true identity despite personal denial, assumed names, or changes in personal appearance resulting from age, disease, plastic surgery or accident (Hoover, 2016). Each ridge of the epidermis (outer skin) is dotted with sweat pores for its entire length and is anchored to the dermis (inner skin) by a double row of peg-like papillae. Injuries such as superficial burns, abrasions, or cuts do not affect the ridge...

...Since then there has been an enormous leap forward on the process used for identifying a person through finger prints. The process went from a lengthy detail examination of a finger print under a magnifying glass; to taking a person finger prints through a Live Scan machine and waiting for the results to return in the matter of seconds. It was not until 1905 that the United States Armed Forces adopted the finger print as a valid form of identification. It was subsequently use by police agencies. By 1980, the first computer database of fingerprints was developed in the United States. It was known as the Automated Fingerprint Identification System, (AFIS). In the present day, there are nearly 70 million cards, or nearly 700 million individual fingerprints entered in AFIS (AFIS. n.d.). Specialized Databases Firefighters, emergency medical services, and law enforcement personnel depend on receiving accurate and prompt information to perform their duties. Radio communications are limited to only convey information verbally, and dispatchers can only transmit information to one officer at the time. Today, technological advances have made it easier for police departments to identify people through a series of databases that contain people’s personal and criminal history as well as photographic images, finger prints, and Deoxyribonucleic acid (DNA).
