BioTone signals

One assurance layer, multiple human signals. BioTone combines multiple signals so policy can require the right assurance for the action.

Current mobile evaluation signals

Four identity matchers plus pulse and presentation checks. Availability depends on build, device, and policy; iris recognition remains experimental.

Periocular

Eye-region matching from camera capture; distinct from experimental iris recognition.

Palm

Texture and line structure from contactless palm imaging.

Voice

Compare the speaker’s voice while they read a fresh, time-limited digit prompt.

Ear

Cartilage geometry from profile capture.

Vitals (PPG)

Use camera-based pulse detection as an additional liveness check when supported.

Presentation

Active liveness challenges (e.g., blink, motion) per session.

Research / design partner

Signals we are testing with the market

  • Workstation dynamics: keystroke and mouse behavior for sensor-constrained desktop workflows.
  • Wearable ECG: opt-in research into contact-based identity signals on compatible wearables.
  • Touch dynamics and other sensor-constrained factors where cameras or microphones are unavailable.

If your environment rules out cameras, microphones, phones, or cloud custody, we want to understand the constraint.
