Biometrics in Physical Access Control
نویسنده
چکیده
Biometrics is a process of identifying a person by their unique and measurable human characteristics. A person’s biometric characteristic can be the size and shape of a hand, the ridge and valley pattern of a fingerprint, the frequency of voice or iris characteristics of the eye. No longer are these devices found only in James Bond movies and Star Trek reruns. They are used on the front door of thousands of businesses around the world. Modern biometrics actually got their start in access control applications as far back as the mid 1970s. The early installations were typically very high security in nature, due primarily to the high cost of biometric devices. In recent years, the advent of inexpensive microprocessors and advanced imaging electronics have dramatically reduced the cost and increased the accuracy of biometric devices. More advanced technologies coupled with affordable components and the demand for high security have allowed biometrics to become a common component in the commercial access control landscape. Today, thousands of businesses use biometrics.

متن کاملAutomatic Configuration for a Biometrics-Based Physical Access Control System
Selecting appropriate thresholds and fusion rules for a system involving multiple biometric verifiers requires knowledge of the match score statistics for each verifier. While this statistical information can often be measured from training data, that data may not be representative of the environment into which each verifier is deployed. To compensate for missing statistics, we present a techni...
