Biometrics verification authenticates identity through biometric liveness and facial recognition. You configure it in your Trust Flow product settings, then run it as part of your verification journey.Documentation Index

How it works
Processes
Biometrics verification runs a pipeline that typically includes:- Liveness detection — Confirms the subject is physically present and the capture is not a replay or static image.
- Facial biometrics matching — Compares the live capture to reference imagery (for example, a document photo) when your flow includes a match step.
Inputs
The main input you collect from the end user is:- Biometric selfie — A live face capture from the device camera (or an uploaded selfie when you allow uploads in tool settings).
Tool settings
You tune behaviour and responses in the product Settings panel. Settings are grouped as below; use the information icons in the portal for field-level help.Verification workflow & automation
| Setting | Purpose |
|---|---|
| Verified when Biometrics Liveness score is above | This is the threshold for the Biometrics Liveness score between 0-1. A higher score indicates a more reliable liveness and spoof detection. |
| Perform injection attack detection | Detects and prevents injection attacks on the biometrics verification process. This feature is only available for Direct Link integration and not available via API. |
| Perform advance face compare | When enabled, will look for source based on the metadata added in the API and look for previous trust validation results with that metadata to extract the biometrics verification to perform face compare with. |
| Perform duplicate detection | Perform duplicate detection to prevent multiple registrations using the same biometrics. If enabled, you can set the action to take when a duplicate is detected. |
| Allow selfie upload | Allow users to upload selfie files instead of capturing with camera. This option is disabled when Face Plus is enabled. |
Output and responses
| Setting | Purpose |
|---|---|
| Return face image | Returns the captured face image from the biometrics verification. |
UI and UX customization
| Setting | Purpose |
|---|---|
| Enable small capturing mode | Reduces the size of the face detection capturing area to a smaller circle for a more compact UI. |
The options available to you reflect what is enabled for your account—so you may not see every setting listed here, and labels can differ slightly. If anything is missing or you need guidance, contact IDmeta support.
