Episode notes
How Biometric Authentication Works
- Biometric systems convert biological measurements like faces or fingerprints into digital signatures for matching.
- These signatures can be stored locally or in central databases, affecting privacy and security.
Biometrics Can Be Spoofed
- Biometric methods are harder to steal than passwords but not immune to spoofing.
- Attackers have used molds, printed irises and AI deepfakes to bypass systems.
Design For An Ongoing Security Arms Race
- Treat biometric security as an arms race between designers and attackers.
- Assume well-resourced attackers may bypass systems and design layered defenses accordingly.
