Episode 45 — Navigate Biometrics Safely: Capture, Storage, and Use
This episode teaches biometric processing as a high-risk domain that requires careful design, because CIPT scenarios involving face, voice, fingerprints, or behavioral biometrics often test whether you understand sensitivity, irreversibility, and downstream misuse risk. We define biometrics as characteristics used to identify or authenticate individuals, and we emphasize how biometric templates, even when not raw images, can remain sensitive and difficult to remediate if exposed. You will learn how to minimize biometric risk through design choices like on-device processing, template protection, strong encryption and key management, strict access controls, purpose limitation, and short retention, as well as governance choices like strong justification and documented risk assessments. We also cover the difference between authentication and identification use cases, and why identification generally increases privacy risk by enabling surveillance and broad matching. Troubleshooting includes handling false positives and false negatives, managing user opt-out or alternatives, and responding to a suspected biometric exposure where traditional password resets do not solve the problem. By the end, you will be able to choose exam responses that treat biometrics with appropriate caution while still enabling legitimate security and usability goals.
