NEWS: Debate over facial alterations to evade Facial Recognition Technology (FRT) has renewed concerns about surveillance, privacy + civil liberties.

ABOUT FRT

• Meaning: Biometric technology that analyses facial features and compares them with images in a database to verify or identify individuals.
• Working: Image Capture → Feature Extraction → Comparison → Matching Decision.
• AI Role: Converts facial characteristics into numerical representations called face embeddings.

TYPES

• 1:1 Verification: Confirms a claimed identity → e.g., Aadhaar face authentication.
• 1:N Identification: Searches a database for possible identity matches → e.g., police investigations.

FACIAL ALTERATIONS + FRT

• Unusual makeup patterns may interfere with facial landmark detection.
• Effectiveness depends on algorithms + lighting + image quality + camera angle.
• Modern systems vary in robustness; makeup is not a guaranteed way to evade FRT.

BENEFITS

• Law Enforcement: Supports CCTV analysis + suspect identification.
• National Security: Identity checks at airports + sensitive locations.
• Public Services: Faster identity verification.
• Financial Inclusion: Alternative to fingerprint authentication.
• Disaster Response: Helps identify missing persons + unidentified victims.
