Physical Zero-Trust Identity

The World's First
Physically-Bound Certificates

Digital identities that die when you unplug the device.
Uncopyable. Unfakeable. Instantly revocable.

Even with root access, attackers can't steal your identity without physically possessing the hardware key.

Trust Infrastructure for
Everything That Computes

Three entity types. One certificate. Prove WHO it is, that it's ALIVE, and it's INTACT.

Human

Voice Biometrics

Prove a person is who they claim to be, alive right now, on their registered device.

Voice print enrollment
Liveness detection
Anti-deepfake protection

AI Agent

Behavioral Fingerprint

Prove an AI agent matches its registered behavior profile and hasn't drifted.

Behavioral enrollment
Drift monitoring
Trust badges

Machine

Hardware Signature

Prove a server, service, container, or IoT device is alive on unique hardware.

Hardware binding (PUF)
Clone detection
7.83Hz heartbeat

TerraLink Key

Turn a normal certificate into a hardware‑bound certificate that can't be copied.

USB trust key that proves your agent/service is alive right now on real hardware. No replays. No clones. No fakes.

Identity Certificates for Runtime Entities

ONE certificate type. THREE proofs. For entities that run, not documents that sit.

WHO

Proves who they claim to be

  • Voice biometrics for humans
  • Behavioral fingerprint for AI agents
  • Hardware signature for services
Use for:
Authentication, KYC, fraud prevention

ALIVE

Proves this is happening RIGHT NOW

  • 7.83Hz physics heartbeat (Schumann)
  • Cannot be backdated or replayed
  • Auto-revokes when hardware disconnects
Use for:
Real-time verification, anti-replay

INTACT

Proves this entity is NOT CLONED

  • Monotonic hardware counter progression
  • Detects cloned devices instantly
  • Behavioral drift monitoring
Use for:
Infrastructure security, compromise detection

What TerraLink Is NOT

We're NOT for static content (documents, images, videos). We're for runtime entities — humans, AI agents, servers, hardware devices — things that need to prove they're alive and authentic RIGHT NOW.

How It Works

Three steps. Hardware-bound certificates.

Bind to Hardware

Use built-in TPM/Secure Enclave or plug in external key. Certificate is locked to physical device.

Bind Identity

Attach human (voice), AI agent, or service to the hardware. Identity inherits device protection.

Certificate Lives

Certificate is valid while hardware is present. Unplug device = certificate dies. Clone detected = instant revoke.

Physical Zero-Trust in Action

Even with root access, attackers can't steal your identity without physically possessing the hardware key.

Banking & Finance

Wire Transfers

Hackers breach your servers? They can't sign transactions without the physical TerraLink Key from your vault.

Server breach → Useless

Healthcare

Patient Records

Laptop stolen with certificates? The certificates are worthless without the hardware key.

Device theft → Useless

Government

Classified Docs

Document signing requires physical possession of the hardware key. No remote compromise possible.

Remote attack → Impossible

Enterprise

CI/CD Pipeline

Production won't deploy unless the hardware attestation device is present in the secure room.

Insider threat → Blocked
