PassiveFaceLiveness (Deprecated)
To use PassiveFaceLiveness, you can either remotely import the
.js
file or download it locally.Include the
.js
file directly from the CDN:<script
src="https://repo.combateafraude.com/javascript/release/passive-face-liveness/<VERSION>.umd.js"
type="text/javascript"
></script>
You can retrieve the class from the SDK using the following code:
const { PassiveFaceLivenessSdk } =
window["@combateafraude/passive-face-liveness"];
Download the
.js
file and import it as an ES6 module:import { PassiveFaceLivenessSdk } from "../assets/js/passive-face-liveness-<VERSION>.js";
In the builder, the SDK receives a single parameter with the settings:
const sdk = new PassiveFaceLivenessSdk(options);
Parameter | Required? |
---|---|
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 |
environmentSettings.disableDesktopExecution Flag indicating whether execution on desktops should be blocked. | No. The default is false |
environmentSettings.disableVisibilityChangeSecurity Disables the security enhancement responsible for closing the SDK when the user switches browser tabs. | No. The default is false |
environmentSettings.disableFaceDetectionSecurity Disables the security enhancement responsible for closing the SDK when the user moves the face away from the mask in automatic capture. | No. The default is false |
capturerSettings.disableAdvancedCapturing Flag indicating whether advanced capture should be disabled*. | No. The default is false |
capturerSettings.disableVideoCapturing Flag indicating whether video capture should be disabled*. | No. The default is false |
appearenceSettings.hideSwitchCameraButton hide the switch camera button. | No |
appearenceSettings.captureButtonIcon Customization of the capture icon accepts values such as image URL or base64 of 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 from 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.isNotAliveMessage Customization of the message when the isAlive parameter returns as false. | No. The default is "Não conseguimos capturar seu rosto :( Por favor, tente novamente." |
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)

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 manually or automatically . In the manual capture, a button will be enabled for the user to perform the capture. |
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. |
const stages = [
{ mode: "automatic", attempts: 3, duration: 60 },
{ mode: "manual", attempts: 0, duration: 0 },
];
Objects are defined for each stage, according to an example, the SDK will start with the automatic capture, where there will be 3 capture attempts or a time limit of 60 seconds for each attempt, after exceeding the time or attempts, the SDK will automatically move on to the next stage, where the manual capture will be performed without time or attempt limits, so the user can perform as many attempts as he/she wants without time limits.
Through the
totalAttempts
parameter you can set the total number of attempts to run the SDK, after reaching the limit value the SDK will automatically terminate.await sdk.capture(sdkContainer, stages, { personData, totalAttempts: 3 });
The SDK has an isolated initialization method, to allow greater control over when it occurs.
During this process, 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.
[!]Initializing 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.
await sdk.initialize();
The 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.
Parameter | Type |
personData.cpf This variable has been deprecated, use personId | string |
personData.name Name of the user doing the authentication (optional). | string |
personData.personId Document number used as a unique identifier for each user (optional). | string |
¹ If not specified, automatic capture is used.
² If not specified, a default value of 30 seconds is used.
// div or another element on DOM
const sdkContainer = document.getElementById("sdk-displayer");
const personData = { personId: "user-identifier", name: "user-name" };
await sdk.capture(sdkContainer, stages, { personData, totalAttempts });
The return consists of an object with the following fields:
Field | Type | Description |
imageUrl | string | Temporary link to the image, generated by our API |
imageKey | string | Object key |
blob | Blob | Blob of the captured image |
const result = await sdk.capture(sdkContainer, stages, {
personData,
totalAttempts,
});
// { imageUrl: '[link da imagem]', imageKey: '[key da imagem]', blob: Blob
The method used to remove the SDK on the canvas, removing the SDK's visual elements from the DOM.
The method used to remove the SDK on the screen.
Will de-initialize the video stream and clear the SDK's internal variables
Soon.
