Synthetic Identity and Deepfake Defence

Detection drills and onboarding hardening

The first of the platform's signature hands-on modules — and one nothing else in the South African market offers. It explains how synthetic identities, forged documents and deepfake audio and video are generated, then drills the detection of them: presentation and liveness attacks, artefacts in synthetic media, and the hardening of a know-your-customer and onboarding workflow against them. You leave with a repeatable detection routine.

Lessons in this module

How synthetic media is made: GANs, diffusion and voice cloning

Explain, at working conceptual level, the three generation mechanisms behind synthetic faces, media and voices — and derive from each mechanism what a detector can and cannot rely on.

25 min

How synthetic identities are assembled — and where they stay weak

Describe the assembly of a synthetic identity and its supporting document set, and identify the structural weak points a verification process can target.

20 min

Detecting synthetic media: artefact classes and their limits

Recognise the principal artefact classes in synthetic images, video, audio and generated documents, and place artefact-spotting correctly as one probabilistic layer in a multi-layer routine.

25 min

Presentation attacks, injection attacks and the truth about liveness

Distinguish presentation from injection attacks on biometric verification, explain what liveness detection does and does not establish, and specify the capture-integrity controls that address the injection gap.

20 min

The detection routine: five steps, every time

Apply Perspica's five-step verification routine — Context, Channel, Artefact, Corroboration, Escalation — to any onboarding or verification decision, and produce the calibrated record it requires.

20 min

Hardening the onboarding workflow: controls, evidence, and the regulator's question

Specify a layered set of onboarding controls against presentation and injection attacks, governed override paths included, and express the design as RMCP-ready, regulator-facing documentation.

20 min

Case 03.2

Case file: The applicant who cleared every check

An applied fact pattern worked against a model resolution, followed by the timed assessment (35 minutes, pass mark 70 percent).

25 min

How it lands across the four desks

Fraud & AML

Central to your desk: a repeatable routine for flagging AI-synthesised identity documents and deepfake media at onboarding, and knowing when to escalate rather than trust a biometric check on its own.

Compliance & Risk

You learn what a defensible verification control looks like now, and how to evidence it to a regulator — the control-design and documentation side of this module.

Wealth & Advisory

Onboarding-facing advisers apply the same detection routine at client take-on, protecting both the client relationship and the firm from a synthetic-identity account opening.

Credit & Underwriting

Underwriters meet the same synthetic-document risk at application stage — the routine that keeps a fabricated identity from ever reaching a credit decision.
