The problem

reCAPTCHA tracks you.
Dexasign doesn't.

Traditional CAPTCHAs like reCAPTCHA track your browsing history across the web to score your "humanness" — a privacy tradeoff most users never agreed to. AI can now solve them anyway. Dexasign verifies real human presence using physical interaction, with no tracking and no data stored.

How it works

Verification that's simple for users,
impossible for bots.

Show your face

User faces the camera for real-time liveness detection. Our AI confirms a real person is present—not a photo or video.

Perform a gesture

A random hand gesture is requested. The user performs it naturally. This combination is impossible for current AI to fake in real-time.

Verified. Done.

You receive a cryptographically signed token confirming human presence. Validate it server-side and proceed with confidence.

Use cases

Why Dexasign

Built different.

Privacy-first

Unlike reCAPTCHA, we don't track your browsing history or build profiles. We verify that a real person is present — nothing is stored, no data leaves the session.

AI-resistant

Current AI can't perform random physical gestures on demand. Our approach stays ahead of deepfakes and automation.

Universal access

Works on any device with a camera. No app downloads. No special hardware. Just a browser.

Lightning fast

Most verifications complete in under 3 seconds. Faster than typing a CAPTCHA, more reliable than solving puzzles.
