Protecting your website from bots is important to protect your organization and customer data. To mitigate risk, many companies use a CAPTCHA on their website.<\/p>\n\n\n\n

In practice, this means that website visitors have to search for traffic lights, click on crosswalks and buses, or recognize which letters and number combinations are hidden behind a blurred image. In recent years, this is how website users have become used to proving that a real flesh and blood human being was logging in to an account or otherwise accessing online content.<\/p>\n\n\n\n

With Google\u2019s reCAPTCHA v3, those days are now over. Let\u2019s look at what has changed, the benefits and limitations of Google reCAPTCHA, and how to comply with the European Union General Data Protection Regulation (GDPR)<\/a> if your company uses it.<\/p>\n\n\n\n

In 2014, Google reCAPTCHA v2 went live and the \u201cI am not a robot\u201d checkbox was born.<\/small><\/p>\n\n\n\n

What is a CAPTCHA and how does it work?<\/h2>\n\n\n

A CAPTCHA (\u201cCompletely Automated Public Turing tests to tell Computers and Humans Apart\u201d) is a security mechanism used to distinguish between real and automated users, such as bots. CAPTCHAs pose tasks that are difficult for computers, but relatively easy for humans to solve.<\/p>\n

The most common type of CAPTCHA involves displaying distorted text or images that the user must interpret and enter correctly. Here’s how it typically works:<\/p>\n

    \n
  1. When accessing a website or performing actions like logging in or making a purchase, a CAPTCHA is triggered.<\/li>\n
  2. The user sees a distorted image with letters, numbers, or objects that are hard for bots to recognize but easier for humans.<\/li>\n
  3. The user types the characters or identifies the objects in the image.<\/li>\n
  4. If correct, the user is verified as human and allowed to proceed; if incorrect, access is denied or a retry is required.<\/li>\n<\/ol>\n

    What is Google reCAPTCHA and how does it work?<\/h2>\n\n\n

    Google reCAPTCHA, including invisible reCAPTCHA, is a free service that helps protect websites from spam and abuse by distinguishing between human users and automated bots or programs.<\/p>\n

    It uses advanced risk analysis techniques powered by artificial intelligence and machine learning to analyze user behavior, device information, IP addresses, and other signals to determine the likelihood that a user is human or a bot.<\/p>\n

    While not perfect, reCAPTCHA’s advanced techniques are more difficult for bots to bypass, providing an effective way to filter out automated spam and abuse on websites. However, it can be bypassed by advanced bots, machine learning systems trained on solving CAPTCHAs, or CAPTCHA-solving services.<\/p>\n\n\n

    Google reCAPTCHA v2 vs v3<\/h2>\n\n\n

    Google offers two main versions of its reCAPTCHA service: reCAPTCHA v2 and reCAPTCHA v3. Here are the key differences between them.<\/p>\n<\/p>\n

    The advantages of reCAPTCHA version 3<\/h2>\n\n\n

    The key advantage of reCAPTCHA v3 is that it can provide a seamless and uninterrupted user experience by working invisibly in the background without presenting any visible challenges or interactive elements, like checkboxes, to users.<\/p>\n

    In addition to more sophisticated bot detection, there\u2019s another benefit to the new version: companies have a lot more control.<\/p>\n

    While version 3 only means that CAPTCHAs are no longer noticeable from the website user\u2019s point of view, it\u2019s about much more than that for website operators. They now have to define granular risk-scoring thresholds for different parts of a website (login, social, payment, etc.), which can include transaction histories and usage profiles from non-Google data.<\/p>\n

    These shifts bring a technical change and, more importantly, sweeping industry change. Website owners must now take responsibility for their bot traffic and cannot simply outsource the issue to third parties.<\/p>\n<\/p>\n

    \"\"<\/p>\n\n\n

    Is Google reCAPTCHA GDPR-compliant?<\/h2>\n\n\n

    The short answer is no, Google reCAPTCHA is not inherently GDPR-compliant when used out of the box on websites, or if it\u2019s poorly implemented.<\/p>\n

    This is because CAPTCHA V3 operates invisibly to the user, which seems convenient but lacks transparency in terms of data processing or protection. User behavior is analyzed behind the scenes, and the user is not informed that the following data, among others, is sent to Google during the analysis:<\/p>\n
