Liveness Detection: Preventing Biometric Spoofing Attacks

Liveness detection distinguishes real users from spoofing attacks. Without it, biometric systems are vulnerable to photos, videos, and masks.

Detection Techniques

Active challenges (blink, turn head) are effective but add friction. Passive detection analyzes texture, depth, and reflections automatically. Multi-frame analysis detects unnatural stillness.

Attack Levels

From printed photos (basic liveness defeats) to real-time deepfakes (requires advanced AI detection). Layer defenses and update continuously.
