With the rapid development of mobile Internet, face recognition technology has gradually been widely used. As a facial recognition application method, facial recognition login has instantly become one of the most popular login methods in mobile applications. So, what if you use the Laravel framework to implement face-based login? This article will introduce readers to how to use facial recognition technology in Laravel to implement the facial login function.

1. What is face recognition technology

Face recognition technology is a technology that can identify face information. It usually uses a camera to obtain face images and combines it with image processing , artificial intelligence and other technologies, analyze the characteristic information in the picture, and achieve the purpose of accurately identifying a person's identity by comparing it with existing face database data.

Nowadays, face recognition technology has been widely used in various industries. For example, in fields such as public security and border security, facial recognition technology has become a necessary technology; in the fields of finance and e-commerce, facial recognition technology is also widely used in business scenarios such as identity authentication and payment.

2. What are the advantages of using face recognition technology to realize facial login in Laravel

Laravel is one of the most popular PHP development frameworks at present, with almost complete functions and Components can greatly reduce the time cost of repeatedly writing and maintaining code. Laravel supports the use of various third-party libraries and packages to implement complex functions, and facial recognition technology is no exception.

Laravel has many advantages for using facial recognition technology to achieve facial login. First of all, the Laravel technology stack is relatively mature, and individuals and small teams can easily use it to implement complex business scenarios. Secondly, Laravel supports installing third-party packages using Composer, and we can easily integrate face recognition technology into our Laravel project. Finally, Laravel has many excellent built-in extension packages, such as Passport (authorization package), Socialite (social authorization package), etc. The existence of these extension packages makes Laravel easier and more efficient when implementing multiple login authentication methods.

3. How to use Laravel to realize facial login

Using face recognition technology to realize facial login in Laravel is mainly divided into the following steps:

Step 1: Install Laravel

Installing Laravel is the first step necessary to use the Laravel technology stack to implement facial recognition login. In this article, we use Laragon tool to install and configure Laravel.

Step 2: Install OpenCV

OpenCV is an open source artificial intelligence vision library that can help us build face recognition functions in Laravel. In this article, we use OpenCV to implement face detection and identity confirmation technology.

Step 3: Install FaceSDK

FaceSDK is an open source face recognition service based on HTTP. It provides functions such as face recognition, face comparison, and face analysis. It also supports automatic Define the face database and face retrieval function. In this article, we use FaceSDK to implement face recognition technology.

Step 4: Front-end page production

Core steps

The following are the core steps to implement the face-based login function:

The first step is in the app A new faceLogin method is added to /Http/Controllers/Auth/LoginController.php, which is used to handle the logic related to facial login, as shown below:

public function faceLogin(Request $request)
{
    // 調(diào)用 FaceSDK 進(jìn)行人臉檢索
}

The second step is in routes/web.php Add a new route in , as shown below:

Route::post('/face-login', 'AuthLoginController@faceLogin')->name('face-login');

The third step is to modify the front-end page and add a "Swipe Face Login" button. When the user clicks the "Swipe Face Login" button, the front-end page passes The camera uploads the user's face image to the backend for face recognition. After the recognition is passed, the user information is stored in the session and jumps to the home page.

<button class="btn btn-primary" type="button" id="face-login">刷臉登錄</button>

<script type="text/javascript">
    $('#face-login').click(function() {
        // 獲取攝像頭并上傳人臉圖像到后端進(jìn)行識(shí)別
    });
</script>

The fourth step is to use FaceSDK to retrieve the user's face image, match the face database information saved in the background, and confirm whether the user is a legitimate user.

function checkFaceImage(faceImage, callback) {
    var formData = new FormData();
    formData.append("api_key", "FaceSDK_API_Key");
    formData.append("api_secret", "FaceSDK_API_Secret");
    formData.append("faceset_token", "Your_Faceset_Token");
    formData.append("image_file", faceImage);

    $.ajax({
        url: "https://api-cn.faceplusplus.com/facepp/v3/search",
        cache: false,
        contentType: false,
        processData: false,
        data: formData,
        type: "POST",
        dataType: "JSON",
        success: function (result) {
            if (result.results[0].confidence > 70) {
                callback(true);
            } else {
                callback(false);
            }
        },
        error: function () {
            callback(false);
        }
    });
}

The fifth step, if the face recognition is successful, save the user information in the session and jump to the home page; otherwise, prompt the user to try logging in again.

if (result.results[0].confidence > 70) {
    $.ajax({
        url: "/login",
        data: {email: "face-login@laravel.com"},
        type: "POST",
        success: function () {
            callback(true);
        }
    });
} else {
    alert("人臉驗(yàn)證不通過(guò)");
}

4. Summary

Using the Laravel technology stack to implement the face-swiping login function can provide users with a faster, safer and more efficient login experience and reduce user authentication time. It can attract more users to register and use by reducing the cumbersome registration process. In the process of implementing facial recognition login, we used OpenCV for face detection and FaceSDK for face recognition and other technologies to ensure the security and stability of the platform. I hope this article can help readers understand how to use facial recognition technology to implement facial login in Laravel and its benefits.
