Understanding reCAPTCHA v3 Enterprise, what is?

ReCAPTCHA is a free service provided by Google that protects your website from spam and abuse. It uses an advanced risk analysis engine and adaptive CAPTCHAs to keep automated software from engaging in abusive activities on your site. It does this while letting your valid users pass through with ease.

However, in its latest iteration, reCAPTCHA v3 Enterprise, some complexities and issues have emerged. Instead of showing a CAPTCHA challenge, reCAPTCHA v3 returns a score so you can choose the most appropriate action for your website. It's a subtle system that operates behind the scenes and allows users to browse websites without interruption.

The reCAPTCHA v3 Enterprise system works by assigning a score to each user interaction, ranging from 0.0 (likely a bot) to 1.0 (likely human). The scoring system is based on interactions across a site, not just on a single page. It uses this score to evaluate whether the interaction is likely to be from a human or a bot.

While the benefits of reCAPTCHA v3 Enterprise include robust protection from automated attacks, there are several concerns and challenges it presents for businesses and users alike.

reCaptcha v3 looks like:

User Experience and Best Practices

One major issue with reCAPTCHA v3 Enterprise lies in its user experience. While the idea of a non-intrusive, frictionless user experience sounds good in theory, in practice, it's not always as straightforward.

Since reCAPTCHA v3 Enterprise operates in the background, users are often unaware they are being evaluated. This lack of transparency can be off-putting for some users who value clarity about data collection practices. Privacy-conscious users might be uncomfortable with the idea of their interactions being scored without their knowledge or consent.

Furthermore, users who are incorrectly flagged as bots can have a frustrating experience as they may face increased scrutiny or even be blocked from accessing certain parts of a website without understanding why. And while false positives can occur with any CAPTCHA system, the opaque nature of reCAPTCHA v3 Enterprise means users can be left in the dark about why they're experiencing difficulties.

Best practices for a smooth user experience involve clear communication about the use of reCAPTCHA v3 Enterprise on a website. Informing users about how their interactions are being evaluated and the purpose behind it can help alleviate some of the concerns.

Advanced settings: Understanding scoring

In advanced applications of reCAPTCHA v3 Enterprise, understanding score interpretation is crucial. However, it's not always clear-cut. The exact factors that go into the score aren't transparent, which can make it challenging for website owners to adjust or improve their scoring over time.

Customizing the reCAPTCHA experience is another aspect that could potentially improve user experience, but it comes with its own set of challenges. For example, it's possible to adjust the sensitivity of reCAPTCHA scoring, but finding the right balance to minimize false positives while still effectively blocking bots can be a process of trial and error.

In conclusion, while reCAPTCHA v3 Enterprise offers a sophisticated tool for distinguishing between human users and bots, its lack of transparency and potential for negatively impacting user experience are significant concerns. Balancing security needs with user experience is a challenge for any online platform, and it's clear that reCAPTCHA v3 Enterprise, while a powerful tool, is not without its issues.

How to identify reCaptcha Enterprise

In the digital world, recognizing the precise security measures employed by a website can be a nuanced task. For those looking to determine if a site is using reCAPTCHA v3 Enterprise, a straightforward method is available. This method involves examining the scripts that the website loads during operation.

One of the identifying features of reCAPTCHA v3 Enterprise is its distinctive script, specifically named 'enterprise.js'. When a website employs reCAPTCHA v3 Enterprise, it must load this script to function correctly. Hence, the presence of this script is a clear indication of the use of reCAPTCHA v3 Enterprise.

The 'enterprise.js' script can be found in the website's source code, generally embedded within a 'script' HTML tag. The source attribute (src) within the 'script' tag points to the location of this JavaScript file. In the case of reCAPTCHA v3 Enterprise, it will point to one of the following URLs:

https://recaptcha.net/recaptcha/enterprise.js
https://google.com/recaptcha/enterprise.js
The HTML script tags would appear as follows:

<script src="https://recaptcha.net/recaptcha/enterprise.js" async defer></script>

<script src="https://google.com/recaptcha/enterprise.js" async defer></script>

The 'async' and 'defer' attributes are used to control how the script is loaded with respect to the rest of the webpage, ensuring it doesn't negatively impact the website's loading speed and performance.

In summary, the presence of the 'enterprise.js' script within the website's source code, sourced from either of the above URLs, is a reliable indicator that the website is utilizing reCAPTCHA Enterprise for its security measures.

How to solve reCaptcha v3 Enterprise

Before we start solving reCaptcha v3 Enterprise, there are some requeriments and points that we need to be aware that they are needed to know
Requeriments:

Capsolver Key: This is an essential component in the process. Capsolver Key is a unique identifier that authenticates your requests to the CAPTCHA solving service.
Proxy: While not strictly necessary, the use of a proxy is highly recommended when dealing with reCAPTCHA v3 Enterprise. A proxy server serves as an intermediary for requests from clients seeking resources from other servers, providing an additional layer of security and anonymity. For optimal results, you may consider using a reliable service.

While the proxy is optional, remember that reCAPTCHA v3 Enterprise places a high level of importance on the IP address. Therefore, using your own proxy is usually beneficial.

Points to be aware that if we don't follow, solution will be invalid:
In order to ensure the effectiveness of the solution, the following points must be meticulously adhered to. Failing to do so may result in an invalid solution:

Correct pageAction: The 'pageAction' field must be accurately populated. This value is integral to how reCAPTCHA functions and incorrect entries will lead to a flawed solution.
Correct websiteUrl: The website URL must be accurate. Any errors in the website URL will result in reCAPTCHA not being able to function correctly, leading to a lower score.
Quality of proxy: The quality of the proxy you use can significantly impact the effectiveness of your solution. Poor quality proxies can lead to low scores.

Remember, if you opt for proxyless methods (using proxies from capsolver), you might end up with a lower score. Hence, it's recommended that you use your own proxy. Adhering to these points is essential in achieving a reCAPTCHA score between 0.7-0.9.

For this example, we will only use the required parameters. The task types for reCaptcha v3 Enterprise are:

ReCaptchaV3EnterpriseTask: This task type requires your own proxies.
ReCaptchaV3EnterpriseTaskProxyLess is using the server's built-in proxy.

We will use ReCaptchaV3EnterpriseTaskProxyLess. The example will be a test page to verify the score of our tokens, this use reCaptcha v3 but not the enterprise version, but we can use as example for testing. The page will be link, we will need proxies (residentials, datacenter, mobile proxies work), capsolver key with balance, correct websiteUrl and correct pageAction.
By default, the pageAction is verify, but the site can customize, so remember that you must check if it’s verify or a custom one, you can also read this to find how page.
For solve reCaptcha v3 for the test site, we will just need to send to capsolver this information:

Step 1: Submitting the information to capsolver

POST https://api.capsolver.com/createTask
{
  "clientKey":"yourapiKey",
    "task":
        {
          "type":"ReCaptchaV3EnterpriseTaskProxyless",
        "websiteURL":"https://antcpt.com/score_detector",
        "websiteKey":"6LcR_okUAAAAAPYrPe-HK_0RULO1aZM15ENyM-Mf",
        "pageAction": "homepage"
        }
}

Step 4: Getting the results

We will need to retrieve the getTaskResult method until the captcha is solved.

Example:

POST https://api.capsolver.com/getTaskResult
Host: api.capsolver.com
Content-Type: application/json

{
    "clientKey":"YOUR_API_KEY",
    "taskId": "TASKID OF CREATETASK" //ID created by the createTask method
}

After the captcha has been solved, you can check the captcha token by sending the token to the site, example:

var request = require('request');
var options = {
  'method': 'POST',
  'url': 'https://antcpt.com/score_detector/verify.php',
  'headers': {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    "g-recaptcha-response": "here the token of capsolver"
  })

};
request(options, function (error, response) {
  if (error) throw new Error(error);
  console.log(response.body);
});

Consequently, the test page will provide feedback regarding the token's score.

In summary, while navigating through the complexities of solving reCAPTCHA v3 Enterprise might seem intimidating, utilizing resources such as capsolver.com can streamline the process significantly. By adhering to the procedures specified above, you're well-equipped to effectively solve reCAPTCHA v3 and achieve a score indicative of human interaction.
