Why does our liveness check still pass a face that was never in the room?

Synthetic faces and virtual-camera injection walk through remote identity checks because most vendors rebadged liveness detection as deepfake protection and still benchmark against public datasets fraudsters solved years ago.

What is the “Why does our liveness check still pass a face that was never in the room?” problem in 2026?

Synthetic faces and virtual-camera injection walk through remote identity checks because most vendors rebadged liveness detection as deepfake protection and still benchmark against public datasets fraudsters solved years ago.

Who has this problem?

Fraud and risk teams at banks, fintechs and marketplaces running remote identity verification at onboarding.

Dataset source note: Most vendors still benchmark against public GAN datasets that fraudsters cracked years ago

Existing players in this space

  • Passive liveness vendors: Built to catch a printed photo or a replayed video, not a live synthetic face driven in real time.
  • Virtual camera detection add-ons: Match known driver names, so anything unlisted passes straight through the check.
  • Document plus selfie matching: Compares two images, both of which can now be generated to match each other.

What existing players are missing

Detection that treats injection and synthesis as two separate attacks: prove the frames came from a real camera on a real device, test the face against current generative architectures rather than a dataset from 2022, and publish the evaluation set with its date so a buyer can see what the score actually covers.
