Capabilities · Biometric Verification
Face, fingerprint, liveness and HANIS — orchestrated in one audited flow. Built to stop the deepfakes, injection attacks and spoofing that bypass legacy biometric checks.
Biometric verification
Most biometric verification stacks weren't built for deepfakes or injection attacks. The threats moved on. Static liveness didn't.
Deepfakes pass legacy liveness checks because they were trained on the same datasets your vendor uses.
Fraudsters skip the camera entirely — feeding a pre-recorded face directly into the verification stream.
The solution
Stopping deepfakes and injection attacks isn't a biometric problem — it's a platform problem. Contactable's biometric layer runs on the Integrated Identity Platform, connected to ID documents, AML signals, fraud intelligence and a shared audit trail. The match is biometric. The defence is the platform.
What we orchestrate
Six layers of biometric verification — working together so identity is proven against the person and defended against the attack.
HANIS validation
HANIS facial and fingerprint validation against the Department of Home Affairs reference — biometric verification with government-backed ground truth, not just statistical similarity. A capability generic facial recognition vendors can't replicate.
Proof of Address
Validate residential and postal addresses against trusted data sources — without forcing customers to dig out a utility bill. Built for FICA address requirements and the audit trail they demand.
Bank Verification
Confirm that the bank account belongs to the customer you've verified — reducing payment fraud and failed disbursements before they happen.
Knowledge-Based Authentication
Knowledge-based authentication adds a layer for cases where documents alone aren't enough — drawing on credit and Home Affairs data to ask questions only the genuine customer can answer.
The biometric verification questions we hear most — from fraud, onboarding, risk and compliance teams across SA enterprise.
Biometric identity verification confirms a customer is who they say they are by matching biometric data — a face image, a fingerprint — against a trusted reference, while also confirming the capture itself is real (not a deepfake, recording or injected image). Contactable's biometric verification combines HANIS validation, facial liveness detection, anti-spoofing and injection-attack defence, deepfake detection and image comparison through one API.
Our deepfake detection looks for signal-level anomalies — pixel artefacts, frequency irregularities and synthesis traces — not visual similarity to known deepfakes. New attacks score the same way as old ones the moment they appear.
Yes. HANIS validates a fingerprint or face against the Department of Home Affairs — South Africa's biometric source of truth. A standard facial check just compares two images you've supplied. HANIS gives the match government-backed ground truth.
Our injection attack defence inspects the data path itself — checking whether the biometric originated from a live device or was injected from elsewhere. Recordings, emulators and stream replacements are blocked at source, before liveness or matching even runs.
Most facial recognition runs against private datasets. In South Africa, Contactable validates faces against HANIS — the Department of Home Affairs reference — so the match has government-backed ground truth, not just statistical similarity. And HANIS sits inside a multi-modal flow that includes liveness, injection defence and deepfake detection, not a standalone face match.
