Strong identity verification
Live ID capture and automated document checks help spot fake or altered identity documents before the session moves forward.
Security & Trust
Secure from start to finish.
ATC Verify verifies the signer, protects the live notarization, keeps signing credentials encrypted, and delivers a tamper-evident final document — all in one online workflow.
Fake-ID detectionAutomated checks help identify altered or suspicious identity documents.
Liveness + deepfake defensesLayered checks help resist replay, spoofing, and AI-assisted impersonation.
Encrypted signing keysPrivate notary signing keys stay protected on secure servers.
Tamper-evident PDFsDigital signatures make later changes to completed documents detectable.
Biometrics & liveness
Your identity is more than a quiz.
Traditional knowledge-based authentication (KBA) asks questions about your past. ATC Verify uses biometric facial matching, government ID checks, and a live selfie to help confirm it’s really you.
Our liveness checks help detect photos, screen replays, and impersonation attempts—adding protection that personal-history questions alone can’t provide.
Your ID. Your live selfie. Added confidence.
Built into the notarization
Security that protects the person, the notary, and the document.
The goal is simple: confirm the signer, keep the live session controlled, protect the notary’s signing credentials, and make the finished document easy to verify later.
Liveness and anti-spoofing
Live selfie checks help defend against photos, screen replays, and other attempts to impersonate the person on the ID.
Deepfake and AI impersonation defenses
Biometric matching, liveness, live capture, and spoofed-photo detection work together to add protection against AI-assisted identity fraud.
Current notary checks
ATC Verify confirms the assigned notary is approved and currently eligible before a notarization can be completed.
Protected digital signing
Private notary signing keys stay encrypted in protected cloud storage and are not exposed in the browser during the session.
Tamper-evident documents
Completed PDFs are digitally signed so a later change to the finished document can be detected by signature-validation software.
Protected digital signing
Private signing keys stay protected.
Notary signing keys are encrypted and kept in protected cloud storage. They stay on secure servers instead of being exposed in the browser during the notarization.
Encrypted cloud storagePrivate signing material stays encrypted while stored.
HSM-backed key protectionBackend encryption keys use FIPS 140-2 compliant hardware security protections.
Certificate controlsInactive or replaced Digital Certificates cannot be treated as current signing credentials.
