Verified by physiology,
not by appearance.
The biological identity layer for mobile — passive authentication from involuntary human motion, on the phone already in the user's hand.
Generative AI has been weaponised.
Facial recognition proves likeness. It can no longer prove life — and deepfake fraud attempts rose roughly 3,000% in 2023 alone as the tools became free and trivial to use.
Liveness is the shield. Identity is the lock.
Trajence Liveness
Independent verification of any video stream — a live session, a captured call, or recorded footage under forensic review. Involuntary-motion analysis produces a per-session liveness verdict with a confidence score.
Trajence Identity
Authentication and identification for high-value transactions and remote video. A per-person motion-print built from involuntary movement dynamics — biological, not behavioural, so it cannot be coached, copied or rehearsed.
Standard biometrics answer one of them.
Our two layers together answer all three — from a single front-facing camera, with no hardware addition.
Face / iris matching
- ✕Spoofed by photographs
- ✕Beaten by masks and faceswaps
- ✕Static checkpoint only
Reflex detection
- ✓Defeats synthetic deepfakes
- ✓Defeats replay and static images
- !A live attacker behind a faceswap can pass liveness
Behavioural signature
- ✓Defeats impostors and account takeover
- ✓Continuous, session-wide
- ✓Catches the faceswap liveness lets through
In a real-time faceswap the attacker is live — liveness sees a living brain, just not the right one. That is why the two layers run in parallel on the same stream.
You cannot perform a reflex.
Move between the two targets as fast as you physically can. Every ballistic human movement — a hand, a finger, a glance — lands on the same lawful speed-amplitude curve, and generated humans obey neither it nor the reflexes beneath it.
Your fastest voluntary movement
Press the magenta target, then move to the cyan one as fast as you can.
The main sequence
Real involuntary movements land inside the band — the cyan strip is where the smallest, fastest corrections live.
This measures your hand — and the same law governs every rapid movement a human body makes. It is an illustration of the principle, not a measurement of our technology: a deliberate movement cannot reach the kinematics of an involuntary one, and the gap is large enough that you can feel it.
A living body never holds still.
Locked on a task, at rest, mid-sentence — the human body produces continuous involuntary motion at every scale: the eyes, the head, the hands, the fingers, the posture. Reflexes, not behaviours. They cannot be performed on command, and generative models do not produce them.
Involuntary micro-corrections the body makes constantly — they cannot be felt, suppressed, or produced on cue.
Present in every living body, absent on command — posture, grip and balance all drift and correct, and never stop while you are alive.
Every rapid human movement — a glance, a reach, a tap — obeys fixed speed-amplitude laws. Generated motion violates them in measurable ways.
No biometric template ever leaves the device.
Enrolled on-device
The personal model is built and matched locally. Privacy is a property of the architecture, not a policy promise.
Short-lived assertion
The output is a signed, expiring assertion — not a template, not raw video, not a face embedding. Template storage is HSM-compatible and never held in plaintext.
Drops into your stack
Built for existing OAuth 2.0 / OIDC, FIDO2 / WebAuthn and FAPI infrastructure, with mTLS and certificate pinning. No new stack.
Built for the moments that carry liability.
Banks carry the loss on a fraudulent wire transfer — not the customer, not the AI vendor. That is where passive biometrics land first.
Step-up authentication
Transaction over a threshold → a short passive check → proceed or block. No prompt, no extra tap, no SMS that a SIM swap can intercept.
Remote video and enterprise calls
A live signal that the participants are present humans, not synthesised ones — verified continuously, not once at join time.
Continuous session assurance
Hands-free re-verification that the person who authenticated is still the person at the device.
KYC and remote identity proofing
Onboarding checks that survive a screen, a printout or a real-time generative model held up to the camera.
Seeing is no longer believing.
Something else has to be.
We are opening partnerships and pilot programmes with financial institutions, identity providers and device manufacturers.
