Installation

npm install @privateid/bravo-web-sdk

Copy the necessary dependencies to the public folder of your app.

"prestart": "cp -R ./node_modules/@privateid/bravo-web-sdk/wasm public/&& cp -R ./node_modules/@privateid/bravo-web-sdk/workers public/",
"prebuild": "cp -R ./node_modules/@privateid/bravo-web-sdk/wasm public/ && cp -R ./node_modules/@privateid/bravo-web-sdk/workers public/"

Add the necessary environment variables on the .env file in the root of your project

SKIP_PREFLIGHT_CHECK=true
REACT_APP_API_URL= 
REACT_APP_API_KEY=

Optional environment variable

REACT_APP_API_ORCHESTRATION=
REACT_APP_SET_CACHE= true | false (Used for predict caching)

Load the WASM Module

The first step is to load and initialize the wasm module.

import { loadPrivIdModule } from '@privateid/bravo-web-sdk';

const isSupported = await loadPrivIdModule();

In case of .env file (evironment variable) does not work for you we have added a support to set the variables on load.

import { loadPrivIdModule } from '@privateid/bravo-web-sdk';

const isSupported =await loadPrivIdModule(
  api_url, 
  api_key,
  api_orchestration_url,
  wasm_url,
);

| Status | Description | |---------------|---------------------------------------------------------------------------------| | api_url | Equivalent to env variable REACT_APP_API_URL | | api_key | Equivalent to env variable REACT_APP_API_KEY | | api_orchestration_url | Equivalent to env variable REACT_APP_API_ORCHESTRATION_URL | | wasm_url | Please set it the same with api_url or REACT_APP_API_URL |

The loadPrivIdModule() function returns an object to check if the device is supporting WASM and WebRTC.

{
    support: boolean,
    message: string,
}

Open or switch camera or close camera

The first step is to load and initialize the wasm module.

Open the camera

To open user camera use the openCamera function with element id of the video tag in the DOM

import { openCamera } from '@privateid/bravo-web-sdk';

const { devices, faceMode } = await openCamera(element);

it returns list of the available video devices.

Switch to another camera

To switch to another media device use the switchCamera function with the ID of the device to be used

import { switchCamera } from '@privateid/bravo-web-sdk';

switchCamera(deviceID);

for the mobile phone we can select whether it's front or back camera for this we pass 'front' or 'back' to the switch function

import { switchCamera } from '@privateid/bravo-web-sdk';

switchCamera('front');

Close the camera

To close user camera use the closeCamera function with element id of the video tag in the DOM.

import { closeCamera } from '@privateid/bravo-web-sdk';

closeCamera(element); // Will specifically look for the element id and will close that camera
closeCamera(); // By default will close opened camera using openCamera

isValid

Live demo: [https://age.devel.private.id]

isValid only exercises the is_valid() call and does not find identity. The function detects if there is a valid face in the camera view or in an ImageData Array.

isValid accepts three parameters.

• callback: callback function to perform actions.
• imageData: imageData to perform the face captcha on (optional)
• config: internal configurable settings (optional)

import { isValid } from '@privateid/bravo-web-sdk';

 await isValid(callback, imageData, config);

Face CAPTCHA returns 26 possible coded results.

| Property | Description | |----------|----------------------------| | -100 | Internal error | | -1 | Invalid image | | 0 | Valid face | | 1 | Image spoof | | 2 | Video spoof | | 3 | Too close | | 4 | Too far | | 5 | Close to right edge | | 6 | Close to left edge | | 7 | Close to top edge | | 8 | Close to bottom edge | | 9 | Too blurry | | 10 | Eye glasses detected | | 11 | Facemask detected | | 12 | Chin too far left | | 13 | Chin too far right | | 14 | Chin too far up | | 15 | Chin too far down | | 16 | Image too dim | | 17 | Image too bright | | 18 | Face low confidence value | | 19 | Invalid face background | | 20 | Eyes closed | | 21 | Mouth open | | 22 | Face tilted right | | 23 | Face tilted left |

Liveness check 7 possible coded results: | Property | Description | |----------|----------------------------| | -100 | Invalid Image | | -4 | Invalid Face | | -3 | Face Too Close To Edge | | -2 | Mobile Phone Detected | | -1 | No Face Detected | | 0 | Real | | 1 | Spoof Detected |

Predict Age

Perform an age estimation using predictAge function on all detected faces from image or camera.

The function takes 4 parameters | Property | Description | |---------------|--------------------------------------------------------------| | callback | The callback function to handle predictAge results. | | config | Internal configurable settings (optional) | | element | The element ID of the video to be used. (optional) | | imageData | ImageData to perform the agePrediction on (optional) |

import { predictAge } from '@privateid/bravo-web-sdk';

await predictAge(predictAgeCallback);

Enroll

Perform a new enrollment (register a new user) using the enroll1FA functio. The function will need 10 concecutive valid faces to be able to enroll. We would need to pass the same enroll_token on success using configuration. If enroll_token changes that means we had an invalid image for enroll and started again from the beginning. (Note: Concecutive 10 face needed.) When enrollment is successful after 10 concecutive valid faces, enroll1FA is returning one enrollment image that can be use for document mugshot comparison, etc.

The function takes 3 parameters | Property | Description | |---------------|--------------------------------------------------------------| | callback | The callback function to handle enroll results. | | config | Internal configurable settings (optional) | | element | The element ID of the video to be used. (optional) |

import { enroll1FA } from '@privateid/bravo-web-sdk';

const image: ImageData | null = enroll1FA(callback, {enroll_token:"token"});

Predict

Perform predict (authenticate a user) using the predict1FA function

The function takes 3 parameters | Property | Description | |---------------|--------------------------------------------------------------| | callback | The callback function to handle enroll results. | | config | Internal configurable settings (optional) | | element | The element ID of the video to be used. (optional) |

import { predict1FA } from '@privateid/bravo-web-sdk';

await predict1FA(callback)

Face Login

Perform Face Login (authenticate a user) using the faceLogin function. Face login performs a more restrictive prediction of face.

The function takes 3 parameters | Property | Description | |---------------|--------------------------------------------------------------| | callback | The callback function to handle enroll results. | | config | Internal configurable settings (optional) | | element | The element ID of the video to be used. (optional) |

import { faceLogin } from '@privateid/bravo-web-sdk';

await faceLogin(callback)

Continuous Authentication

Perform continuous user prediction (authentication) using the continuousAuthentication function. This provides the same status updates as Predict.

import { continuousAuthentication } from '@privateid/bravo-web-sdk';

continuousAuthentication(callback, configuration, element)

The continuousAuthentication function takes 4 parameters

| Property | Description | |----------|--------------------------------------------| | callback | The callback to be executed on each status | | configuration | Please use recommended: { input_image_format: "rgba" } | | element | (Optional) Element ID of the video tag where the camera is open. |

isValidPhotoID

This function finds, crops, align and validate, front and back of the photoID, and returns back a valid cropped and aligned image of the photoID

import { isValidPhotoID } from '@privateid/bravo-web-sdk';

//Front of DL scan 
const { imageData, croppedDocument, croppedMugshot } = isValidPhotoID("PHOTO_ID_FRONT", documentCallback);

// Back of DL barcode scan
const { croppedBarcode, croppedDocument } = isValidPhotoID("PHOTO_ID_BACK", callback)

The isValidPhotoID function takes 3 parameters

| Property | Description | | -------- | ----------------------------------------------------------------------------------------------- | | docType | it can be either PHOTO_ID_BACK (back of the photo ID) or PHOTO_ID_FRONT (front of the photo ID) | | callback | returns the uuid of the portrait on the Front of the Photo ID |

The function returns:

Front Document Scan (PHOTO_ID_FRONT) imageData: ImageData datatype of the input image croppedDocument: Uint8ClampedArray convertable to base64String of the cropped document. If document scan is unsuccessful, this will return null croppedMugshot: Uint8ClampedArray convertable to base64String of the cropped face. If document scan is unsuccessful, this will return null (Note: Please use utilty function below for converting images to base64 string.)
