Enabling faceio with Vue.Js
With the widespread use of the internet for various applications, the need for secure user authentication
has become increasingly important. While traditional methods such as email and password authentication
and third-party authentication providers have been commonly used, the emergence of facial recognition
technology has provided a new and innovative approach. In this article, we will explore how to incorporate
facial recognition authentication into your web application using the popular JavaScript framework,
Vue.js. Specifically, we will be utilizing Faceio's facial recognition authentication and providing step-bystep instructions on how to integrate it into your Vue.js application. Whether you are a developer looking
to enhance your web app's security or simply interested in learning about the latest advancements in web
authentication, this article is for you.
Reasons for implementing face authentication technology
Face authentication is gaining popularity because it provides a more convenient and safe way to
authenticate users than conventional techniques like email and password authentication. visage
authentication allows users to instantly verify their identity by simply presenting their visage to a
camera. By removing the need for users to manually enter passwords or recall them, this can lower the
risk of password-related security breaches. Face authentication is a trustworthy method of preventing
fraud and identity theft because it is difficult to trick or imitate.
As shown by the application we are going to create using a Vue.js application with FaceIO's facial
recognition feature using the fio.js library, facial recognition technology is simple to integrate into web
applications. This library manages the intricate details of facial recognition, making integration easy.
Additionally, by removing the need for users to recall passwords, facial recognition can make their user
experience more convenient. As is the case with FaceIO, an extra layer of verification, such as a PIN, can
be added to further increase security. Users only need to enable the camera to scan their face for
authentication when using facial recognition.
How secure is your data with Faceio
In the age of big data, businesses treat data as a priceless asset and make every effort to safeguard the
information of their clients. When using products, users expect data security, and any web application
that requires user authentication must meet these expectations. FaceIO is among the safest methods
for user authentication for a number of reasons. The first reason is that it complies with privacy laws like
the GDPR and CCPA, which carry stiff penalties for businesses who violate privacy standards. In order to
ensure that users' photos are safe, FaceIO only stores a hashed key of each image rather than the actual
images themselves. Second, FaceIO's model boasts high accuracy ratings of nearly 100%, an impressive
feat that calls for a significant amount of high-quality data.
Implementing face authentication by building a registration application with Faceio and Vue.Js
Step 1
Certainly, let's proceed with developing your simple application. The user interface will consist of three
buttons - one for registering, one for signing in, and one for logging out. The application's functionality is
straightforward - the user must register first, then sign in, and after doing so, the logout button will
become visible while the other two buttons will disappear. This is the desired outcome for the
completed project. First lets create a Vue.Js face-recognition project. Make sure that you have installed
Node.Js and NPM , and the Vue CLI is installed globally then create a new Vue.js project;
vue create faceRecognition
Step 2
Sure, the next step is to add fio.js to our project. To do this, you can navigate to the HTML file and add a
div element with the ID "faceio-modal" and the fio.js Content Delivery Network (CDN) at the end of the
body.
<div id="faceio-modal"></div> <script
src="https://cdn.faceio.net/fio.js"></script> <script> const faceio = new
faceIO('Your app id goes here'); window.faceio = faceio; </script>
Another approach to accomplish this is by assigning the faceIO object to the window.faceio variable and
creating an instance in the Vue.js JavaScript code while storing the app ID in a .env file.
Moving on, to update the App.vue file, you can replace the HelloWorld component with an
AuthenticationComponent and include the CSS code below. As a result, the App.vue component will
have a new appearance that reflects these changes.
Step 3
Alright, let's proceed with updating the Authentication.vue file, which was previously the HelloWorld
component. Firstly, we will clear the template and add three buttons - one for login, one for registering,
and one for logout. Additionally, we need to create a user state and initialize its value to an empty
string.
Using the v-if attribute, we can ensure that the login and registration buttons are visible only when the
user is not logged in, while the logout button is visible only when the user is logged in. We will also
associate each button with its respective click event, which we will define shortly. To style the UI, I have
added some basic CSS. The resulting template will look something like this:
Step 4
Sure, moving on to the JavaScript part, the first step is to create a state variable to keep track of the
users. This can be achieved as shown below:
Step 5
Certainly, the next step is to create the login, register, and logout functions:
The logout function is straightforward as it simply sets the user state variable to an empty string. On the
other hand, for the register function, we can use the method provided by fio.js, which can be accessed
from the window object. This function requires a payload object that contains data that will be returned
when the same user logs in again. The code for this function is relatively simple and is shown below.
Step 6
Great! You can find the documentation for the fio.js library here.
Moving on to the login function, fio.js also provides a method for user login that returns the data passed
as an argument to the enroll function when the user registered. Here's how it works:
Conclusion
In conclusion, facial recognition authentication technology is becoming increasingly popular due to its
convenience and safety in verifying user identities. Integrating this technology into web applications is
also becoming simpler with the use of libraries such as fio.js. With FaceIO, an extra layer of security,
such as a PIN, can be added to increase security, and the technology is compliant with privacy laws,
ensuring the safety of user data. In this article, we have provided step-by-step instructions on how to
incorporate FaceIO's facial recognition feature into a Vue.js web application. By following the steps
outlined in this article, developers can implement facial recognition authentication into their own web
applications, enhancing user experience and increasing security.
