Aerendir A‑LIVE®

Passive liveness verification SDK for mobile apps.
Aerendir A-Live® uses a phone's built-in accelerometer and gyroscope to detect real-time physiological micro-vibrations and verify that a live human is present—in ~0.5 seconds, with on-device AI, and no camera, CAPTCHA, or user friction.
For login, account recovery, transaction approval, signatures, and bot defense.

Aerendir® A-Live® Technology

Watch how A-Live® detects human presence using physiological signals—no CAPTCHAs, no friction, just seamless verification.

What it is
A software SDK/API for liveness verification
How it works
Reads sensor motion signals, extracts micro-patterns, classifies live vs. not live on-device
Why it matters
Stops spoofing, bots, replays, and deepfake attacks at the human-presence layer

The Missing Layer in Security: Human Presence Verification

Most security systems verify credentials or appearance—but not whether a living human is physically present at the moment of access. A-Live® adds that missing layer by verifying liveness through physiological motion signatures that are extremely difficult to spoof with AI, bots, replays, masks, or voice clones.

Why Legacy Systems Fail

Security without liveness verification is fundamentally broken.

Iris Scanners
Photos and contact lenses easily defeat iris scanners without live signal detection.
Voice Auth
AI voice clones replicate any voice with startling accuracy.
Deepfakes & Masks
Deepfakes and 3D masks bypass facial recognition without physiological verification.
Bots & AI
Bots and AI scale attacks across millions of accounts instantly.
Stolen Credentials
Passwords and tokens are replayed, phished, and stuffed at massive scale.
CAPTCHAs
Solved by AI farms and ML models faster than humans can complete them.
Legacy systems all verify what something looks like—not whether a human is present.

Applications

Use Cases

Combating internet zombification, making the internet real again.

Single-Factor/Standalone

Adds liveness verification inside any login system. SDK provides a checkmark confirming a live human, integrated into the third-party company's own login process. Stop bots from posting.

Frictionless Dual Factor

Instead of receiving a code to type in, you receive a prompt on your phone (or your phone is pinged) for you to hold it for half a second, and you're in.

Legal & Compliance Verification

Establish the human and legal provenance of digital signatures, contracts, and regulatory submissions with irrefutable liveness proof.

Real Human for Ad Tech

Verify impressions, confirm human authenticity, and stop ad-click fraud. Eliminate wasted spending on fake clicks and bot traffic—ensure your ads reach verified humans. A-Live® can save the advertising industry billions lost annually to fraudulent traffic.

Technology

Why Aerendir® A‑Live®?

Live Physiology

Detects real-time physiological signals originating from the nervous system to verify human presence

Formidable Barrier to Spoofing

Neural complexity cannot be imitated—even by the most sophisticated AI training models

Frictionless

Seamless verification in .5 sec with no CAPTCHAs, ReCAPTCHAs, NoCAPTCHAs, no challenges, no user interaction required

AI

Cloudless AI — No Personal Data

Fully on-device processing—no network connectivity, external compute resources, or personal data collection needed

How A-Live® Technology Works

As brain signals move through the nervous system, microscopic adjustments occur, causing involuntary micro-vibrational movements influenced by a person's unique motor brain structure, neural firing patterns, and muscle fiber composition. Our technology detects these signals using existing device sensors.

MEMS Sensors

Accelerometer & gyroscope in mobile devices are so sensitive they capture invisible micro-vibrations

On-Device AI

Pre-trained classifier processes signals locally—no cloud required

Live/Not Live

99.99% accurate human verification in 0.5 seconds
