Exam CAS-005 topic 1 question 53 discussion

✅ D. Biometric impersonation 🔍 Explanation: Facial recognition is a form of biometric authentication. One of the key risks associated with it is: Biometric impersonation – the unauthorized replication or spoofing of someone's biometric data (in this case, their face) to gain access to a system or device. Attackers might use photos, 3D models, or videos to trick facial recognition systems. Once biometric data is compromised, it cannot be changed, unlike passwords. ❌ Why the other options are incorrect: A. Data remanence Refers to residual data left on storage devices after deletion — not specific to facial recognition. B. Deepfake A deepfake is a synthetically altered video or image, which could be used as a method of biometric impersonation, but it's not the risk itself — it's a tool for impersonation. C. Metadata scraping Involves extracting metadata from files or communications — unrelated to facial recognition authentication.
