Jaakrecog Liveness© Component is an isolated component of Angular that is easy to integrate that allows you to capture the video process in order to make a liveness, which was developed by JAAK-IT.

Tech

Technologies used for the development of this library:

• Angular
• Scss
• Typescript
• Rxjs
• Angular Material

Installation

Jaakrecog Liveness requires Node.js v10+ to run.

Install the package:

npm install jaakrecog-liveness-lib

Setup

Declare on import of JaakrecogLivenessLibModule module

    JaakrecogLivenessLibModule.forRoot({
      apiUrl: 'https://dev.api.jaakrecog.com',
    }),

Usage

Uses the asynchronous function openVideoCapture found in the JaakrecogLivenessLibService service

    import { JaakrecogLivenessLibService } from 'jaakrecog-liveness-lib';

      initCaptureVideo(): void {
         this.jaakrecogLivenessSrv.openVideoCapture('your_token_here')
           .then((data) => {
                   console.log(data);
               })
           .catch((error) => {
                   console.log(error);
             });
  }

The response of this promise would be a class named BestFrame

  class BestFrame {
    bestFrame!: string;
    evaluation!: number;
    facesFound!: Array<string>;
    id!: string;
    message!: string;
    processTime!: number;
    status!: boolean;
  }

We can get an error and it will return an error of type ErrorResponse

 class ErrorResponse {
 type!: string;
 message!: string;
 }

Another alternative of use, that we can implement is through the selectors, for this it uses in an HTML file

<ngx-capture-video [token]="your_TOKEN" [stream]="MediaStream" (getBestFrame)="yourFunction($event)"></ngx-capture-video>

This method of use requires obtaining the userMedia previously or leaving it null for the component to raise the request for camera permissions.
