Fraud signals that go beyond document verification

Document verification is necessary but no longer sufficient. Sophisticated fraud rings now submit documents that pass visual and even forensic checks, because the underlying identity is synthetic rather than forged.

Device intelligence and behavioral signals — how quickly a form is filled, whether the device has been associated with prior fraud, patterns in typing and navigation — provide a second layer of defense that doesn't rely on the document being fake.

The institutions with the lowest fraud loss ratios combine both layers, and route only ambiguous cases to human review.
