What is the purpose of Biometric Authentication?

Biometric authentication is specifically designed to verify a person's identity by analyzing unique physical characteristics. This method relies on traits such as fingerprints, facial recognition, iris scans, or voice patterns. The primary purpose is to enhance security measures by ensuring that only authorized individuals can access certain systems or information.

Using physical traits for authentication provides a level of security that traditional methods, such as passwords or PINs, often lack. Since biometric features are unique to each individual, they create a more robust barrier against unauthorized access. Additionally, biometric systems can be convenient, eliminating the need to remember complex passwords or carry physical tokens.

The other options, while important in their own contexts, do not relate to the primary function of biometric authentication. High-speed internet is unrelated to identity verification; securing application containers pertains to software security rather than user identity; and data encryption focuses on protecting information itself rather than authenticating users. Thus, the correct answer reflects the core purpose of biometric systems in the field of authentication.
