# FaceTec

FaceTec (opens new window) is a third-party eIDV provider integrated with the Assure API. Combining FaceTec with Assure's identity verification capabilities, increases the confidence in the onboarding process and prevents fraud attempts.

# Supported features

Signicat supports the following identity verification features from FaceTec:

  • Face match between ID document and selfie
  • Liveness check of live video recording

# User flow example

More information will follow soon.

# SDKs

The aim of this topic is to help a developer integrating with the Assure API using FaceTec's SDKs (iOS, Android and web).

Please, keep in mind that the following descriptions do not contain all the necessary steps for production mode. In addition, you must add validations, tests and error handling, which is outside the scope of this documentation.

Using the third-party SDKs means that the end-user will see FaceTec's user interface when performing the identity verification on their mobile or desktop.

Check "liveness" of end-user

The main aim of FaceTec's user interface is to check the "liveness" of an end-user against an image of the end-user’s face.

Before you start the SDK integration, we recommend to familiarise yourself with the general steps for integrating with the Assure API.

# Requirements

Before you start the integration, you should be aware of the following requirements for all FaceTec's SDKs:

# Mobile SDKs (iOS and Android)

# Integration steps overview

This diagram provides an abstraction of the client-side implementation.

The next sections describe all the needed steps, including the integration with Assure before and after the FaceTec SDK integration in step 4:

  1. Create a dossier.
  2. Create a process.
  3. Add a photo to the process.
  4. Integrate with the FaceTec SDK to capture liveness images.
  5. Start verification.
  6. Get result.


All the steps are similar for iOS and Android except the SDK integration in step 4, which is described below in different tabs for iOS and Android.

# Create a dossier

  • Use the Create dossier (opens new window) endpoint to create a placeholder for all of your end-user’s data.
  • Save the dossierId you get in the response to be used in the next requests.


Ensure you use one dossier per end-user.

# Create a process

  • Use the Create process (opens new window) endpoint to create an identity verification process in that dossier. Ensure you give it the dossierId you got in the Create dossier response. Also, enter the FaceTec provider in the request body:

When you have created the FaceTec process, you should get a backend response like this:

  "processId": "74ee35d5-f542-472e-a087-597bc28bc9d4", 
  "status": "pending",
  "createdAt": "2021-01-05T10:54:47Z", 
  "updatedAt": "2021-01-05T10:54:47Z",
  "authorization": "someAuthorizationToken",
  "facetecEncryptionPublicKey": "somePublicKey",
  "facetecDeviceKeyIdentifier": "someDeviceKeyIdentifier",
  "facetecProductionKeyText": "someOtherKey",
  "provider": "facetec"
  • Save the information from the response. You will need it in the next steps.

# Add a photo to the process

The FaceTec liveness process needs to compare the liveness data (that will be obtained in the next step) with a photo of the person who is supposed to match that liveness data.

The most common use-case is that you have a photo from someone you already know is the valid owner of an ID document and then want to use FaceTec to get liveness evidence from that person.

To do that, you first create another process in the Assure API and use it to verify a person’s identity using an ID document. Then you can get the photo of that person from that process (see Get Image (opens new window)) and feed it to the FaceTec process (Set Image (opens new window) “selfie”).

# Integrate with the FaceTec mobile SDK to capture liveness images

To capture the live images from the end-user, you must now integrate with the FaceTec SDK for either Android or iOS:

# Start verification

Your server (backend) must request the Assure API to start performing the identity verification.

To do this, you must send the necessary fields you got in the app to the backend, and then the backend communicates with Assure by calling Start verification (opens new window) with this request body:

    "facetecEnrollment": { 
        "faceScan": "string",
        "auditTrailImage": "string",
        "lowQualityAuditTrailImage": "string",
        "userAgent": "string"

# Get result

When the verification is finished, you can call the Get process (opens new window) result to get the result of the identity verification. Here is an example of an accepted process:


The process is accepted because both the matching of the selfie with the liveness video and the liveness check were successful.

The process is rejected if any of the conditions mentioned before is false.

Download full result

You can also get a zip file with the packaged process by calling the Download full result (opens new window) endpoint.
