Biometrics: Are YOU the Key to Security? Biometrics is used to perform either identification or authentication, the latter being the most common application. In identifying, a sample is presented to the biometric system during enrollment. The system then attempts to determine if a biometric record exists for the sample by comparing it with a database of samples in the hope of finding a match to determine the identity. This is most commonly associated with fingerprint analysis in crimes. In authenticating, the biometric system attempts to verify an individual's identity by capturing a new sample and comparing it to a stored template. If the two samples match, the system confirms that individual is who they claim to be. The main difference is that identification compares a sample against a database of many and verification compares a sample against a database of one. Both methods involve a four-stage process: capture, extraction, comparison, and result.

Shedding some light on Voice Authentication Biometric authentication technology and development has grown over the last 6 years from being something we have seen on Science fiction television shows into a reality where w e can now purchase the systems and implement them both in our business and private lives. In this paper I will attempt to explain, in non -technical language, the technologies behind one particular type of biometric authentication, voice authentication. I will look at the human voice, how this is captured by technology, and how this can then be used to verify that the person is who they claim to be.

Biometric Scanning Technologies: Finger, Facial and Retinal Scanning This paper discusses several Biometric scan technologies: finger-scan, facialscan and retinal-scan. We discuss the recent history of Biometrics and how it has been influenced by such pseudo-sciences as Phrenology, the study of human skull characteristics and Anthropometry, the study of human body measurement. We discuss how finger-scan technology was influenced by French and British police advancements in the nineteenth century and still remain the most widely used Biometric technology today. Facial-scan technology is beset with privacy concerns especially when this technology is applied to unsuspecting crowds. Retinal-scan technology, is a relatively new entrant to the biometric field and offers significant promise. One of the continuing challenges for the biometric industry is to define the environment in which the technology provides the strongest benefit to individuals and institutions.

Strengthening Authentication with Biometric Technology One of the fastest growing crimes in America today is identity theft, providing data confidentiality and integrity is vital if businesses want to combat this growing epidemic. This paper will look at the danger and cost of identity theft, uncover the problem with current authentication practices, demonstrate how a biometric solution can be used to provide stronger authentication, and look at the added benefit of using multiple factor authentication practices.

When To Use Biometrics The focus of this paper is not the possible use-cases of biometry, but rather it is those limitations that are neither biometry-type specific nor implementation specific and that make biometric measures limited in their scope of possible uses. Biometric systems become common over the years. Their ease of use for the end user and their perceived security make them seem to be the best solution to any problem involving user authentication. Although biometric systems can provide fast and secure user authentication with minimal user intervention, they have several inherent limitations making them inappropriate for most environments where authentication is used.
