Is the right person authorizing it?
Binding of credentials to the legitimate user. A-Cert® ties a key or credential to the human behind it, so possessing the secret is not enough — the real person must be present. A-Cert® is a transport layer with an encryption engine that is fully NIST compliant.
The key is the person.
A-Cert® derives a biocryptokey — bound to the user’s physiology and their device at once. Authorization succeeds only when the legitimate human is present. A-Cert® works with any biometric credentials already present on the user’s mobile device.
Bind
A credential is derived from the user’s physiology, any present biometric, tied to the device, and stored as a key.
Authorize
At the moment of authentication, the live human signal (or any other biometric) must match.
Transport
The biocryptokey, or any biometric-generated key, moves securely, without the key ever leaving the user. 100% NIST compliant.
A stolen secret is not a person.
- Credentials bound to the legitimate user
- Biocryptokey transport layer with any biometric
- Two-factor by design — user and device together
- SDK / API — drops into existing authentication flows
Where authorization must be real.
Step-up authorization
Require the legitimate human for sensitive actions inside an existing session — not just a re-typed password.
Payments & transfers
Bind high-value transactions to the real account holder, cutting account-takeover and authorized-push-payment fraud.
Privileged access
Gate admin consoles and critical infrastructure on the present, legitimate operator.
Signing
Tie document and contract signatures to the actual signer, with two factors in a single touch.
