Identity Verification (IDV)
The process of confirming that a person is who they claim to be, typically at account opening. Common signals: government ID document scan, selfie with liveness, address verification, device and behavior signals.
Identity verification is a fraud problem with an accuracy budget: every control that stops a fraudster also rejects some genuine customers, and the right operating point differs between a bank and a marketplace. Document plus liveness is the current baseline, deepfake-resistant liveness is the active arms race, and reusable credentials are the direction of travel, because verifying once and presenting many times is cheaper and less invasive than re-proofing at every relationship.
