How is fingerprint data kept safe? Select three correct answers, then submit.

Fingerprint data is kept secure through several mechanisms. First, it's not stored as a raw image but as a template, a mathematical representation derived from sensor data using an algorithm. This template is then stored in a Trusted Execution Environment (TEE), a hardware-isolated secure area within the device's processor. This ensures that even if the main operating system is compromised, the fingerprint data remains protected. Furthermore, applications do not directly access this sensitive data. Instead, when an app requests authentication, the TEE performs the comparison and returns only a "passed" or "failed" result, preventing apps from ever seeing or extracting the actual fingerprint template. Sending fingerprint data to Google for storage would be a significant privacy and security risk, which is why it's not done.
