Introducing FACEIO NPM Package

TLDR; FACEIO is a facial authentication framework that is to be implemented on websites or web applications via simple JavaScript snippet (just like Disqus or Google Tag) to easily authenticate users via Face Recognition instead of the traditional login/password pair or OTP code.
FACEIO is a cross-browser, Cloud & On-Premise deployable, facial authentication framework, with a client-side JavaScript library (fio.js) that integrates seamlessly with any website or web application desiring to offer secure facial recognition experience to their users...
Put it simply, FACEIO is the easiest way to add passwordless authentication to websites or web applications. Simply implement fio.js on your website, and you will be able to instantly authenticate your existing users, and enroll new ones via Face Recognition using their computer Webcam or smartphone frontal camera on their favorite browser.
Once fio.js implemented on your website, you'll be able to instantly recognize your existing users, on-board new members securely with maximum convenience, and at real-time thanks to passwordless experience powered by face recognition.

`fio.js` LIBRARY & WIDGET INTEGRATION

The FACEIO Widget is a simple and elegant interface to provide secure facial authentication experience to your users via simple calls to the enroll() & authenticate() methods. The Widget is powered by the fio.js JavaScript library, which is simple enough to integrate in a matter of minutes while being flexible enough to support highly customized setups. Once implemented on your website or web-based application, you'll be able to authenticate your existing users, enroll new ones securely, with maximum convenience on their favorite browser, and at real-time thanks to passwordless experience powered by face recognition.

fio.js works with regular webcams, and smartphones frontal camera on all modern browsers, does not require biometric sensors, and works seemingly with all websites and web applications regardless of the underlying front-end technology used (ie. React, Vue, jQuery, Vanilla Javascript, static HTML, etc.) or server-side language or framework (eg. PHP, Python, Node.js, Rust, Elixir, etc.).

It’s super quick to get FACEIO Up & Running with just few lines of code. Follow the walkthrough below to implement fio.js on your site.

STEP 1 - IMPORT fio.js TO YOUR SITE

import faceIO from '@faceio/fiojs'

const faceio = new faceIO('app-public-id') // Get the application Public ID at https://console.faceio.net.

👉 You shouldn't run fio.js functions right after initiating it.

💡 Take a look to our community contributed tutorials listed here. They should help you implement fio.js on your website or web application using your favorite JavaScript framework whether it is React, Vue, Angular, Next or Vanilla JavaScript.

STEP 2 - INVOKE THE WIDGET

import faceIO from '@faceio/fiojs'

const faceio = new faceIO('app-public-id'); // Get the application Public ID at https://console.faceio.net.

function App() {
    return (
    <div className="App">
        <button onClick={enrollNewUser}>Enroll New User</button>
        <button onClick={authenticateUser}>Authenticate User</button>
    </div>
    );
}

async function enrollNewUser() {
    // call to faceio.enroll() here will automatically trigger the on-boarding process
}
async function authenticateUser(){
    // call to faceio.authenticate() here will automatically trigger the facial authentication process
}
function handleError(errCode){
    // Handle error here
    // Log all possible error codes during user interaction..
    // Refer to: https://faceio.net/integration-guide#error-codes
    // for a detailed overview when these errors are triggered.
    const fioErrs = faceio.fetchAllErrorCodes();
    switch (errCode) {
    case fioErrs.PERMISSION_REFUSED:
        console.log("Access to the Camera stream was denied by the end user");
    break;

ENROLL() - ENROLL NEW USER

‎

SYNTAX

const userInfo = await faceio
.enroll({ parameters })
.catch(errCode => {
  /* handle the error */
})

console.log(userInfo)

ALIAS

enrol(), register(), record()

PARAMETERS

enroll() takes a single, optional parameters object with the properties to be configured. The table below lists all possible properties of the parameters object:

‎

| Property Name | Type | Default Value | Description | |--------------------|-----------------------|---------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | payload | Any Serializable JSON | NULL | An arbitrary set of data, you want to associate with the user being enrolled. Example of useful payloads includes Email Address, Name, ID, Token, and so on. This payload will be forwarded back to you upon successful future authentication of this particular user. Maximum payload size per user is set to 16KB. | | permissionTimeout | Number | 27 Seconds | Total number of seconds to wait for the user to grant camera access permission. Passing this delay, the ongoing enroll() operation is aborted and the promise is rejected with the fioErrCode.PERMISSION_REFUSED error code. | | termsTimeout | Number | 10 Minutes | Total number of minutes to wait for the user to accept FACEIO/Host Application Terms of Service. Passing this delay, the ongoing enroll() operation is aborted and the promise is rejected with the fioErrCode.TERMS_NOT_ACCEPTED error code. | | idleTimeout | Number | 27 Seconds | Total number of seconds to wait before giving up if no faces were detected during the enrollment process. Passing this delay, the ongoing operation is aborted and the promise is rejected with the fioErrCode.NO_FACES_DETECTED error code. | | replyTimeout | Number | 40 Seconds | Total number of seconds to wait before giving up if the remote FACEIO processing node does not return a response (a very unlikely scenario). Passing this delay, the ongoing operation is aborted and the promise is rejected with the fioErrCode.TIMEOUT error code. | | enrollIntroTimeout | Number | 12 Seconds | Enrollment Widget introduction/instruction screen display delay. | | locale | String | auto | Default interaction language for the Widget display. If this value is missing or set to auto, then the interaction language will be deducted from the Accept-Language HTTP request header. Otherwise, just pass the BCP 47, two letter, language code of your choice (en, ar, es, ja, de, etc.). If the requested interaction language is not supported, the fallback, default interaction language is US English: en-us. | | userConsent | Boolean | false | If you have already collected user consent before enrollment (eg. When the user create a new account on your Website and accept the terms), you can set this parameter to true. In which case, the Terms of Use consent screen is not displayed for the end user being enrolled. It is your responsibility to explicitly ask for consent before enrolling a new user. For additional information, please consult our Privacy Best Practices for applications. |

‎

SYNTAX

‎

const boolean = await faceio.restartSession({})

PARAMETERS

‎ None

RETURN VALUE

ERROR CODES

‎ The table below lists all possible error codes that are returned from either the enroll() or the authenticate() methods when their promises are rejected respectively.

| Error Code | Description | Effect on enroll() or authenticate() | |--------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | fioErrCode.PERMISSION_REFUSED | Access to the camera stream was denied by the end user. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.TERMS_NOT_ACCEPTED | Terms & Conditions set out by FACEIO/host application rejected by the end user. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.SESSION_IN_PROGRESS | Another authentication or enrollment operation is processing. This can happen when your application logic calls more than once enroll() or authenticate() due to poor UI implementation on your side (eg. User taps twice the same button triggering the facial authentication process). Starting with fio.js 1.9, it is possible now to restart the current user session without reloading the entire HTML page via simple call to the restartSession() method. | Ongoing operation is still processing and the FACEIO Widget continue running. Your error handler routine should probably ignore this error code as the operation is still ongoing. | | | | fioErrCode.FACE_DUPLICATION | This error code is raised when the same user tries to enroll a second time on your application. That is, his facial features are already recorded due to previous enrollment, and can no longer enroll again due to the security settings: Prevent Same User from Enrolling Twice or More being activated. | Ongoing enroll() operation is immediately aborted and control is transferred to the host application. | | | | fioErrCode.TIMEOUT | Ongoing operation timed out (eg, camera Access Permission, ToS Accept, Face not yet detected, Server Reply, etc.). | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.NO_FACES_DETECTED | No faces were detected during the enroll or authentication process. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.UNRECOGNIZED_FACE | Unrecognized/unknown face on this application Facial Index. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.MANY_FACES | Two or more faces were detected during the enroll or authentication process. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.PAD_ATTACK | Presentation attack (PAD), better know as face spoofing attempt is detected during the authentication process. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.UNIQUE_PIN_REQUIRED | Supplied PIN Code must be unique among other PIN's on this application. This warning code is raised only from the enroll() method, and only if you have enabled the Enforce PIN Code Uniqueness Security Option. | Ongoing enroll() operation is still processing until the user being enrolled input a unique PIN code. | | | | fioErrCode.FACE_MISMATCH | Calculated Facial Vectors of the user being enrolled do not matches. This error code is raised only from the enroll() method. | Ongoing enroll() operation is immediately aborted and control is transferred to the host application. | | | | fioErrCode.WRONG_PIN_CODE | Wrong PIN Code supplied by the user being authenticated. This error code is raised only from the authenticate() method. | Ongoing authenticate() operation is immediately aborted after three trials and control is transferred to the host application. | | | | fioErrCode.NETWORK_IO | Error while establishing network connection with the FACEIO processing node. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.PROCESSING_ERR | Server side error. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.UNAUTHORIZED | Your application is not allowed to perform the requested operation (eg. Invalid ID, Blocked, Paused, etc.). Refer to the FACEIO Console for additional information. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.UI_NOT_READY | The FACEIO fio.js library could not be injected onto the client DOM. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.TOO_MANY_REQUESTS | Widget instantiation requests exceeded for freemium applications. Does not apply for premium applications as fio.js instantiation is unmetered. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.EMPTY_ORIGIN | Origin or Referer HTTP request header is empty or missing while instantiating fio.js. This error is raised only if you have enforced the Reject Empty Origin Security Option. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.FORBIDDDEN_ORIGIN | Domain origin is forbidden from instantiating fio.js. This error is raised only if you have created a white list of authorized domain names via the FACEIO Console. | Ongoing operation is immediately aborted and control is transferred to the host | | fioErrCode.FORBIDDDEN_COUNTRY | Country ISO-3166-1 Code is forbidden from instantiating fio.js. This error is raised only if you have created a white list of authorized countries via the FACEIO Console. | Ongoing operation is immediately aborted and control is transferred to the host |
