Biometric Security
Biometric security is a technology that uses unique biological or behavioral characteristics of individuals to verify their identity for authentication and access control purposes. It relies on traits such as fingerprints, facial features, iris patterns, voice, or gait, which are difficult to forge or replicate. This approach enhances security by replacing or supplementing traditional methods like passwords or PINs with more personalized and secure identifiers.
Developers should learn biometric security when building applications that require high-security authentication, such as in banking, healthcare, or government systems, to protect sensitive data and prevent unauthorized access. It is particularly useful in mobile apps, IoT devices, and physical access systems where user convenience and strong security are priorities, as it reduces reliance on memorized credentials and mitigates risks like phishing or password theft.
