FaceAuthenticator (Deprecated)

Importing SDK

To use FaceAuthenticator, you can either remotely import the .js file or download it locally.

Remotely

Include the .js file directly from the CDN:

<script src="https://repo.combateafraude.com/javascript/release/face-authenticator-deprecated/<VERSION>.umd.js" type="text/javascript"></script>

You can retrieve the class from the SDK using the following code:

const { FaceAuthenticatorSdk } = window['@combateafraude/face-authenticator'];

Locally

Download the .js file and import it as an ES6 module:

import { FaceAuthenticatorSdk } from '../assets/js/face-authenticator-<VERSION>.js'

Construction

In the builder, the SDK receives a single parameter with the settings:

const sdk = new DocumentDetectorSdk(options);

Supported parameters

Parameter	Required?
token Authentication token for consuming the SDK.	Yes.
language Default message language, valid values: en_US, en_BR, es_MX.	No. The default is pt_BR
analyticsSettings Analytics Configuration Objects.	No.
analyticsSettings.disableAnalytics Parameter responsible for enabling or disabling analytics.	No.
analyticsSettings.trackingId Unique id that we are going to save the information from this SDK execution.	No.
analyticsSettings.trackingInfo We accept an information object.	No.
environmentSettings.disableDesktopExecution Flag indicating whether execution on desktops should be blocked.	No. The default is false
capturerSettings.disableAdvancedCapturing Flag indicating whether advanced capture should be disabled*.	No. The default is false
appearenceSettings.captureButtonIcon Customization of the capture icon accepts values such as image URL or base64 SVGs.	No
appearenceSettings.captureIconSize Customization of the icon size for the captureButtonIcon field.	No
appearenceSettings.captureButtonColor Customization of the default image capture button color.	No
appearenceSettings.switchButtonIcon Customization of the camera switch icon accepts values such as image URL or base64 SVGs.	No
appearenceSettings.switchIconSize Customization of the icon size for the switchButtonIcon field.	No
appearenceSettings.switchIconColor Customization of the color of the default camera switching icon.	No
appearenceSettings.fontFamily Changes the font for all elements contained in the SDK.	No. The pattern is inherited from the page
textSettings.messages.processMessage Customization of the image processing message.	No. The default is "Processando sua foto, aguarde um momento"
textSettings.messages.captureFailedMessage Customization of the capture failure message.	No. The default is "Ops! Tivemos um problema ao processar sua imagem."

* Advanced capture consists of using more complex and not-so-stable APIs in browsers that support them (e.g. ImageCapture)

Example

const sdk = new DocumentDetectorSdk({
    token: `my-sdk-token`,
    language: `pt_BR`,

    analyticsSettings: {
      disableAnalytics: false,
      trackingId: "",
      trackingInfo: "",
    },

    environmentSettings: {
        disableDesktopExecution: false,
    },


    appearenceSettings: {
        hideCaptureTitle: false,
        hideCaptureMask: false,
        hideCameraSwitchButton: false,
        useGenericMask: false,
    },

    capturerSettings: {
        disableAdvancedCapturing: false,
    },

    textSettings: {
        messages: {
            processMessage: '',
            wrongDocumentMessage: '',
            bothWrongSideMessage: '',
            wrongSideMessage: '',
            lowQualityMessage: '',
            captureFailedMessage: '',
        }
});

CaptureStage

CaptureStage allows the client to configure the stages. To do this, we offer the CaptureStage object, where you can set the following parameters:

Parameter

mode Desired capture mode. It can be used manual, automatic or upload. In the manual capture, a button will be enabled for the user to do the capture, in the upload, the functionality of uploading documents will be displayed instead of capturing.

attempts The number of attempts of the current stage. If it is the only stage, the value 0 must be passed.

duration Duration time of the current stage. If more than one stage is set, the total time for each stage can be set, and when the total time is reached, the stage will move on to the next one. Set it to 0 if you don't want to set a time for the stage.

Example CaptureStage

const stages = [
  { mode: "automatic", attempts: 3, duration: 60 },
  { mode: "manual", attempts: 3, duration: 60 },
  { mode: "upload", attempts: 0, duration: 0 },
];

Initialization

initialize(): Promise<void>

The SDK has a separate method of initialization, to allow greater control over when it occurs.

During this initialization, the SDK will initialize its internal variables and download the resources it needs to run.

[!] You must call this method before using other SDK methods.

[!] The initialization of the SDK can take a few seconds. We recommend that you call this function as early as possible in your flow so that opening the SDK is smooth for the user.

Example

await sdk.initialize();

Utilization

Opening and taking selfies

capture(container: HTMLElement, stages, {personData?: PersonData, totalAttempts?: Number}): Promise<Result>

Method used to load the SDK onto the screen and perform selfie capture.

It will initialize the video stream (requesting permissions if needed) and load it into the container.

Parameters

Parameter	Type
personData.cpf CPF of the user doing the authentication (required).	string
personData.name Name of the user doing the authentication (optional).	string

¹ If not specified, automatic capture is used.

² If not specified, a default value of 30 seconds is used.

Example

// div or another element on DOM
const sdkContainer = document.getElementById('sdk-displayer');
const personData = { cpf: 'user-cpf', name: 'user-name' };
await sdk.capture(sdkContainer, stages, {personData, totalAttempts});

Return

The return consists of an object with the following fields:

Field	Type	Description
requestId	string	Unique identifier of the requisition
isMatch	boolean	Boolean indicating whether the captured face is identical to the face registered for the entered peopleId
peopleId	string	Information of the document reported for authentication
openEyesProbability	number	Probability of eyes being open in captured selfie

Close SDK

close(): Promise<void>

The method used to remove the SDK on the screen.

De-initialize the SDK

dispose(): Promise<void>

The method used to remove the SDK on the screen.

Will de-initialize the video stream and clear the SDK's internal variables
