A-Live® · Liveness Detection

Is a Human or a Bot/AI Bot present?

Passive detection of a living human, read from neuromuscular micro-vibrations as the human holds the device. Presence confirmed in a second or less, with or without a challenge and no camera.

No matter how smart or well-coded a bot or AI-bot is, it has no heartbeat or “brainbeat.”
How it works

Commodity sensors

The accelerometer and gyroscope already in every phone capture the faint micro-vibrations of a hand at rest — no camera, no extra hardware.

On-device AI

A pre-trained classifier reads those micro-vibrations locally, directly from the sensor, and separates a living human from a recording, bot, or synthetic signal. No cloud, no network round-trip.

Alive or not alive

A presence decision is returned, ready to gate a login, a form, or a transaction in your own product flow.

What you get

Built to drop into what you already run.

  • A-Live achieves over 99.5% accuracy
  • Passive — zero added friction
  • Entirely on-device
  • 0.5-1 seconds runtime
  • SDK / API — integrates into any existing login or access flow
  • Extends to laptops and consoles via the phone as a second factor
Use cases

Wherever a real human must be in the loop.

Standalone liveness

Add a human-present check inside any login or sign-up. A-Live confirms a live person before access is granted — stopping bots from registering, posting, or scraping at scale.

Frictionless second factor

Instead of typing a code, the user is pinged on their phone and simply holds it for half a second. The same proof extends to laptops and consoles via the phone.

Complements your stack

A-Live detects live human presence at the device itself, rather than inferring it from behavioral patterns or data trails, acting as a fundamentally different, complementary layer to your data-centric stack. No PII, no extra hardware, and it can run continuously or on demand.

Built for agentic AI

Nowadays, agentic AI mimics legitimate sessions perfectly, but human presence at the device is the one signal it cannot fake. A-Live can operate beyond banking, fintech, social media, and more — anywhere autonomous agents now operate.
