Why does liveness detection matter?
A face recognition system matches a face to a stored record. But a match alone does not prove a live person is at the camera. An attacker can show a printed photo or a screen video.
Liveness detection closes this gap. It confirms that a real person is at the camera in real time.
How does liveness detection work?
Liveness detection reads signals from the face and the camera. Two main methods exist: active and passive.
- Active liveness asks the user to move. The user blinks, smiles, or turns the head.
- Passive liveness needs no action. It reads texture, depth, and light from one frame.
- Some systems combine both methods for more strength.
How does liveness detection relate to presentation attack detection?
People often use these two terms together. Presentation attack detection (PAD) is the formal name in the ISO/IEC 30107-3 standard. Liveness detection is the common name for the same goal.
PAD adds a strict taxonomy and a test method. Both terms describe the work to stop a fake face.
How does SenseCrypt use liveness detection?
SenseCrypt is a passwordless identity provider (IdP). The user signs in by face. SenseCrypt runs face matching on-device.
The SenseCrypt liveness detection holds iBeta ISO 30107-3 certification. This certification covers Level 1 and Level 2 presentation-attack detection.
Frequently asked questions
What is liveness detection?
Liveness detection is a security check that confirms a real, live person is at the camera. It separates a live face from a photo, a video, or a mask.
Does liveness detection stop a photo attack?
Yes. Liveness detection checks that a face is real and present. It rejects a printed photo or a screen video.
Is liveness detection the same as presentation attack detection?
The two terms share one goal. Presentation attack detection (PAD) is the formal term in the ISO/IEC 30107-3 standard. Liveness detection is the common name.
Does SenseCrypt use certified liveness detection?
Yes. The SenseCrypt liveness detection holds iBeta ISO 30107-3 certification. It covers Level 1 and Level 2 presentation-attack detection.
