Capture
- Know cameras grab an image or video
- Assume capture happens without your consent
- Expect high-quality frames feeding the system
Detection
- The system locates a face in frame
- It pins key facial landmarks
- It isolates your face from the scene
Feature Extraction
- Unique features get measured precisely
- Measurements convert into a digital faceprint
- The template encodes your identity numerically
Matching
- Faceprint is compared against stored templates
- Each comparison returns a confidence score
- The system seeks the closest match
Decision
- A score above threshold confirms identity
- Matches above threshold grant access
- Low confidence rejects or flags you
The Database
- Encrypted templates sit ready for comparison
- Stored faceprints persist far beyond capture
- A security layer guards against spoofing
Where Deployed
- Watch for access control at buildings
- Expect device unlock on phones and laptops
- Assume surveillance scans for persons of interest
Privacy Stakes
- Demand consent and data minimization
- Question retention and bias in the model
- Treat every faceprint as a lasting risk
