BACKGROUND ON BIOMETRICS• New research field: <strong>Biometric</strong> cryptosystems• Research goals:•How to generate cryptographic keys out of biometricmeasurements• how to hide and retrieve user-specific cryptographic keys inand out of biometric data• how to generate several forms of biometric templates from asingle biometric measurement
KEY CONCEPTS IN BCS• Current cryptosystems depends on the secrecy of thesecret or private key and authentication is possession-based• Systems don’t know if the user is a legitimate person or anattacker.• <strong>Biometric</strong>s replaces password-based authentication•They can also be used to generate a cryptographic key orbiometric hash
