Trust Stamp adds liveness checks so humans approve AI-agent transactions

Trust Stamp introduced a biometric authorization system called Knowing Consent on November 12, designed to let banks verify a customer's identity before processing a financial transaction initiated by an AI agent. According to Biometric Update, the point is not to block agents from reaching an account but to separate access from approval of one specific payment.

Under conventional setups, once a customer hands credentials or delegated access to a third-party agent, there is little room for a per-transaction confirmation. With Knowing Consent, the customer first enrolls biometrically to create a personal identity token; when an agent initiates a transaction that needs approval, either the agent or the financial institution can trigger an authorization request.

The customer receives a prompt by SMS, email or push notification and submits a live biometric selfie. Trust Stamp then runs biometric matching, liveness detection and anti-spoofing checks to confirm that the enrolled account holder is present at the moment of approval.

The authorization screen shows the specific transaction and its details before the customer completes verification, binding the approval to that individual action. That detail matters: it turns consent from a blanket account permission into a traceable confirmation tied to an amount, a payee and a purpose.

Financial institutions can integrate through their existing Orchestration Layer or with a single API call. CEO Gareth Genner says the system can be deployed within days under existing authentication and transaction policies, and Trust Stamp reports more than 100 financial institutions already integrated with its Orchestration Layer.

The intellectual property is moving in parallel: the company filed a U.S. provisional patent application, No. 64/195,409, covering the process on November 11, adding to its existing portfolio. It previously built Trusted Authentication for high-value and high-risk transactions, and Knowing Consent extends the same biometric confirmation to transactions initiated by agents.

The backdrop is that major U.S. banks have restricted third-party AI agents from accessing customer accounts over concerns about credential sharing and unauthorized transactions, while vendors such as iProov are advancing similar human-approval specifications. As agents begin moving money on people's behalf, who gets to press confirm is becoming a core compliance question for financial AI.
