Validates that a real person is performing the registration by combining Liveness with Behavioral Alert — no document capture or government identifier required.
What this use case solves
Fraud Risk Level Detection addresses the challenge of validating that a real person is performing the registration, without requiring document capture or identity verification through a government identifier — all within a single process.
By combining Liveness with Behavioral Alert, the pipeline confirms the presence of a real person in front of the camera and, simultaneously, checks whether that face carries risk signals in the Unico network. The result is an onboarding decision based on behavioral trust, not just documentary data.
Use this use case when:
- Your operation suffers from fraud where the identity is legitimate but the intention is criminal.
- You need to identify and block identity fraud attempts where users open accounts with synthetic identities.
- You need to identify and block Mule Account attacks, where users open multiple accounts across different institutions to launder money.
- You want to mitigate Bust-out Fraud by detecting users who generate sudden hyperactivity in the network.
- Your business model requires that each individual holds at most one active account per operator (or per country).
Do not use this use case when:
- You only need to validate the static integrity of a document against a government database → use Onboarding.
- You only need to know if this face is the same one that completed onboarding → use 1:1 Validation.
Capabilities involved
Pipeline executed within a single process:
| Capability | Role in the flow |
|---|---|
| Liveness (Optional) | Confirms that the selfie belongs to a living person, mitigating deepfake or injection attacks. Ensures input integrity before behavioral analysis. |
| Fraud Risk Classification | Cross-references transaction data (face, code, history) with the global network history. Applies statistical models to generate the final risk level for that transaction. |
Prerequisites
- Bearer token — OAuth2 authentication via Client Credentials. See Authentication.
- APIKEY enabled — Key configured for V3 with behavioral analysis permission. See Environments.
- Primary key (
subject.code) — The identifier performing the transaction: document number, email, or phone number.
It is highly recommended to send metadata and context alongside the request. This includes registration data (name, date of birth, gender, and other information), email, phone, and clientReference. Using our Liveness solution also enriches the analysis with device risk, location, and additional behavioral signals.
Step-by-step implementation
- Native
- Web
- API
Integration via native SDK — capture runs inside your app using the Unico SDK for Android, iOS or Flutter.
- Install the SDK — add the Unico SDK dependency for your platform. See the setup guide for Android, iOS or Flutter.
- Create a process — call Create Process with the appropriate
flowvalue and the user's identifier. Use the returnedtokento initialize the SDK. - Start the capture — the SDK renders the camera UI and performs liveness detection on-device, returning the captured payload.
- Query the result — call Get Process to retrieve the capability results.
- Apply business rules — evaluate the response fields to approve, deny or escalate.
Integration via iFrame, Redirect or Native — Unico hosts the capture UI, and you receive the result via polling.
- Create a process — call Create Process with the appropriate
flowvalue and the user's identifier. The response includes auserRedirectUrl. - Redirect the user — send the user to
userRedirectUrl. Unico renders the capture journey. OrwebAppTokenin native apps. - User completes the journey — after capture, the user is redirected back to your
callbackUri. - Query the result — call Get Process to retrieve the capability results.
- Apply business rules — evaluate the response fields to approve, deny or escalate.
Direct API integration — capture the selfie using the Unico SDK or your own UI following the Capture Standard, then send the image directly to the Unico API.
- Capture the selfie — use the Unico SDK for your platform, or build your own UI following the Capture Standard, to obtain a selfie image that meets liveness requirements.
- Create a process — call Create Process with the appropriate
flowvalue, the user's identifier and the selfie asimagebase64. - Query the result — call Get Process to retrieve the capability results.
- Apply business rules — evaluate the response fields to approve, deny or escalate.
