Introduction to Biometric Identification Database Essay

Introduction to Biometric Identification Database - Essay illustrationBut the evolution of biometry in the form of automated identification of finger prints, geometry of hand, flagst maven construction, seventh cranial nerve structure, genetic makeup etc. is a relatively new phenomenon. Portuguese explorer Joao de Barros also points out1 the cosmea of Biometrics in China in the 14th century. Barros narrates that Chinese merchants used to stamp their childrens palm prints and footprints on a piece of paper with ink. This way the Chinese merchants used to distinguish the young children from one a nonher. This usher out be termed as the beginning of the modern biometrics. The recent advances in Information Technology and computing arrive at provided newer dimension to this emerging field. During the last couple of decades biometrics has established itself as a comprehensive mechanism for establishing Identities and Verification.In 1890, Alphonse Bertillon, a Parisian police desk, studied body length to identify criminals. Subsequently the method came to be know as Bertillonage method, which relied heavily on measuring the body length. But the method did not last long as there were many dour alarms as a result of false identifications. Thereafter, finger printing became the reliable method of identifying the criminals. There are human rights groups and civil liberties advocates argue that increase use of biometrics has resulted in trespassing into the privacy of all human beings, but the rise in terrorist activities in recent years has forced the defense and security experts to rely heavily on the biometrics for identifying the mischief makers.Types of Biometrics and their usageA biometric system is designed to test one out of the two possible hypotheses (Wayman et al., 2005) (1) That the submitted samples are from an individual known to the system or (2) That the submitted samples are from an individual not known to the system. Applications to test the f irst hypothesis are called positive identification systems (verifying a positive claim of enrollment), piece applications testing the latter are negative identification systems (verifying a claim of no enrollment). Biometrics, in frequent can be divided into two main groups, physiological and behaviorali. Physiological factors These factors depend upon the bodily structure and appearance of the individual.Iris Scan The Iris of an individual is scanned to match it with the stored image. Quite often the iris scan may not come out with actual on if the person is putting on dark glasses, or is suffering from some eye disease.Fingerprint This is one of the oldest tried and tested methods of biometrics. In fact the nail is also included for identification in fingerprinting.Hand This includes the structure of knuckles, palm and the vascular networking of hand.Face, Earlobe, Lips The camera scans the facial structure or the fleshy pendulous part of the external ear or lips of the individ ual.Voice The voice is also one of the most distinguishing features to identify an individual. Therefore the voice patterns form one of the most dependable biometric measures. Retina like iris, the retinal structure too provides an insight into the nature and character of the person.desoxyribonucleic acid This method too is quite frequently used in a number of cases to establish the identity of the individual.Body Odor and Sweat Pores There are biometric techniques which can sense the
