Golang implements live face detection? Baidu AI interface helps you do it!

With the rapid development of artificial intelligence technology, face liveness detection has become one of the important links in the field of face recognition. Through liveness detection, you can effectively prevent being deceived by videos, photos, etc., and improve the security of the face recognition system. In this article, we will introduce how to use the Golang programming language to implement face liveness detection, and use Baidu AI interface to assist development.

First, we need to create an application in the Baidu AI open platform and obtain the corresponding API Key and Secret Key.

Then, we need to install Golang’s HTTP request library, which can be installed using the following command:

go get github.com/go-resty/resty/v2

Next, we can use the following code example to implement live face detection:

package main

import (
    "fmt"
    "github.com/go-resty/resty/v2"
    "io/ioutil"
)

func main() {
    apiKey := "<Your API Key>"
    secretKey := "<Your Secret Key>"

    // 读取待检测的图片
    imagePath := "<Path to your test image>"
    imageBytes, err := ioutil.ReadFile(imagePath)
    if err != nil {
        fmt.Println("Failed to read image file:", err)
        return
    }

    // 调用百度AI人脸活体检测接口
    url := "https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=" + apiKey + "&client_secret=" + secretKey
    resp, err := resty.New().R().Get(url)
    if err != nil {
        fmt.Println("Failed to call Baidu AI API:", err)
        return
    }

    accessToken := resp.String()

    url = "https://aip.baidubce.com/rest/2.0/face/v3/faceverify?access_token=" + accessToken
    resp, err = resty.New().R().
        SetFile("image", imageBytes).
        Post(url)
    if err != nil {
        fmt.Println("Failed to call Baidu AI API:", err)
        return
    }

    // 处理返回结果
    fmt.Println(resp.String())
}

In the above code, you need to replace <your api key></your> and <your secret key></your> with the ones you obtained when creating the application in Baidu AI Open Platform API Key and Secret Key. At the same time, you need to replace <path to your test image></path> with the path of the image to be detected.

In the code, we first obtain the AccessToken required to access the Baidu AI interface through an HTTP request, and then use the AccessToken to call the face liveness detection interface. Finally, we can perform further processing by parsing the returned results, such as outputting detection results or performing subsequent business logic processing.

It should be noted that since the face liveness detection interface is part of Baidu AI interface, you need to register and obtain the relevant API Key and Secret Key to successfully call it.

Face liveness detection is a very challenging technology, but with the support of Baidu AI interface, we can easily implement this function using Golang. I hope this article can help you and make your face recognition system safer and more reliable!
