How To Do Aadhar Authentication And Live - Face Matching?

by ADMIN 58 views

Introduction

In today's digital age, authentication and verification are crucial aspects of any online application or service. Aadhar, India's unique identification number, has become a widely accepted method of authentication. In this article, we will explore how to integrate Aadhar authentication and live face matching into your application using JavaScript.

What is Aadhar Authentication?

Aadhar authentication is a process of verifying an individual's identity using their Aadhar number. The Unique Identification Authority of India (UIDAI) provides a set of APIs and services to facilitate Aadhar authentication. The process involves sending a request to the UIDAI server with the Aadhar number, which then responds with a response containing the authentication status.

Why Use Aadhar Authentication?

Aadhar authentication offers several benefits, including:

  • Security: Aadhar authentication provides a high level of security, as it uses a unique identification number that is linked to the individual's biometric data.
  • Convenience: Aadhar authentication eliminates the need for users to remember multiple passwords or PINs.
  • Accuracy: Aadhar authentication reduces the risk of identity theft and ensures that the user is who they claim to be.

How to Integrate Aadhar Authentication

To integrate Aadhar authentication into your application, you will need to follow these steps:

Step 1: Register with UIDAI

To use the Aadhar authentication API, you need to register with the UIDAI. You can do this by filling out the registration form on the UIDAI website.

Step 2: Obtain an API Key

Once you have registered with the UIDAI, you will receive an API key. This key is used to authenticate your requests to the UIDAI server.

Step 3: Send a Request to the UIDAI Server

To send a request to the UIDAI server, you will need to use the following API endpoint:

https://uidai.gov.in/uidai/Authentication/Authentication/AuthenticationRequest

You will need to pass the following parameters in the request:

  • AadhaarNumber: The Aadhar number of the user.
  • Pin: The PIN of the user.
  • Mode: The mode of authentication (e.g., "EID" for electronic ID or "OTP" for one-time password).
  • AuthenticatorType: The type of authenticator used (e.g., "EID" for electronic ID or "OTP" for one-time password).

Step 4: Verify the Response

The UIDAI server will respond with a JSON object containing the authentication status. You will need to verify the response to determine whether the user is authenticated or not.

Live Face Matching

Live face matching is a feature that allows you to verify the user's photo with the one in their Aadhar. To implement live face matching, you will need to use a library such as FaceAPI or Face++.

Step 1: Install the FaceAPI Library

To use the FaceAPI library, you will need to install it using npm or yarn.

npm install face-api

Step 2: Load the FaceAPI Model

To load the FaceAPI model, you will need to use the following code:

const faceapi require('face-api');

faceapi.loadFaceModel('https://storage.googleapis.com/face-api/faceapi.min.js');

Step 3: Capture the User's Photo

To capture the user's photo, you will need to use a library such as Webcam or MediaRecorder.

const webcam = new Webcam();

webcam.capture().then((photo) => {
// Process the photo
});

Step 4: Compare the Photos

To compare the photos, you will need to use the FaceAPI library.

faceapi.compareFaces(photo1, photo2).then((result) => {
  // Process the result
});

Example Code

Here is an example of how you can integrate Aadhar authentication and live face matching into your application:

const express = require('express');
const app = express();
const faceapi = require('face-api');

faceapi.loadFaceModel('https://storage.googleapis.com/face-api/faceapi.min.js');


app.post('/authenticate', (req, res) => {
const aadhaarNumber = req.body.aadhaarNumber;
const pin = req.body.pin;
const mode = req.body.mode;
const authenticatorType = req.body.authenticatorType;


const options = 
method 'POST',
url: 'https://uidai.gov.in/uidai/Authentication/Authentication/AuthenticationRequest',
headers: {
'Content-Type': 'application/json',
,
body: 
AadhaarNumber aadhaarNumber,
Pin: pin,
Mode: mode,
AuthenticatorType: authenticatorType,
,
};


axios(options)
.then((response) => {
const authenticationStatus = response.data.authenticationStatus;


  if (authenticationStatus === 'AUTHENTICATED') {
    const webcam = new Webcam();

    webcam.capture().then((photo) => {
      faceapi.compareFaces(photo, response.data.photo).then((result) => {
        if (result.similarity > 0.5) {
          res.json({ authenticated: true });
        } else {
          res.json({ authenticated: false });
        }
      });
    });
  } else {
    res.json({ authenticated: false });
  }
})
.catch((error) => {
  console.error(error);
  res.json({ authenticated: false });
});



});


app.listen(3000, () => {
console.log('Server listening on port 3000');
});
