To begin, while many people support biometrics, under the impression that they provide utmost security, they are not fully aware of the many flaws that exists which if abused can lead to severe, negative consequences. In order to function properly biometric technologies require all ideal conditions to be met. If a single condition is not met then biometrics are utterly useless. Relying on a technology where a single error could compromise security completely is hardly practical. In addition, in “The State of the Art in the Abuse of Biometrics” Heana Buhan and Pieter Hartel, both who have lots of experience with data privacy and security management, state that the system of biometrics requires that none of the administrators are “hostile” or malicious, coined “NOEVIL”. Relying on a system that is only as honest and accurate as the person operating it is redundant. Since no one can ever know what the true intentions of an administrator are, biometric technologies will always be vulnerable to abuse. Finally, biometric technologies do not always work properly, resulting in false positives and negatives. For example, biometric systems have many problems with aging and health. As people age some of their characteristics become more pronounced, while others become subtler. The systems do not take this into consideration, resulting in authorizing people who are not supposed to be authorized and denying authorized people. Also, these systems do not consider health as an aspect. Voice recognition may not work if a person has a cold, if person becomes an amputee finger scanners will no longer for them or if a person is suffering from liver problems and has jaundice iris scanners will reject them. As one can see, while biometric systems sound ideal on an elementary level they are rather new technologies that require serious solutions before they can safely be relied on for security.
