privacy-preserving biometrics

Privacy-preserving biometrics refers to techniques that protect individual biometric data—like fingerprints or facial features—during identification or verification processes. It ensures that sensitive data remains confidential, even when used for security checks, by transforming or encrypting the information so it cannot be easily accessed or misused by unauthorized parties. These methods enable accurate identification without revealing or storing raw biometric details, thereby enhancing security and respecting user privacy in applications like access control and digital authentication.
