Biometrics refers to the identification of individuals based on unique physical or behavioral traits, making it a more reliable method than traditional password-based authentication. The document discusses various types of biometric identifiers, their functionality, and the criteria for selecting biometric systems, emphasizing the benefits of secure and accurate identity verification. Despite challenges in widespread adoption, the document asserts that the use of biometrics is expanding in corporate and business settings.

authentication, refers to the identification of
humans by their characteristics or traits.
What Is Biometrics?

4. Biometrics, also known as biometric
authentication, refers to the identification of
humans by their characteristics or traits.
Since biometric identifiers are unique to individuals, they are
more reliable in verifying identity than token and knowledge-
based methods.

28. In the End…
Even though Biometrics are considered by many to be too
sophisticated, cumbersome and costly to be used on a wide
scale, the scope of Biometrics is steadily increasing, both in the
corporate and business world. There are many problems that
are being faced in the widespread installation of this technique,
but those problems are slowly being conquered.
Biometrics are the technology of tomorrow…
