Mechanisms for biometric authentication

Biometric authentication, which uses unique physical or behavioral traits to identify users, has emerged as a critical component in improving identity security. Biometrics provides a diverse and safe solution to authentication in an environment driven by digital interactions. This investigation dives into various biometric authentication systems, emphasizing the need for digital signatures and public-key cryptography to provide safe authentication.

Digital signatures and public-key cryptography are foundational technologies for ensuring the security of identity verification processes. Public-key cryptography employs a pair of cryptographic keys: a public key that may be freely disseminated and a private key that is kept private. These key pairs are used to produce digital signatures, which assure the validity and integrity of digital messages or documents.

In the context of biometric authentication, public-key cryptography is critical for...
