reCaptcha vs hCaptcha: A Guide to Choose the Right Captcha

“Security in IT is like locking your house or car – it doesn’t stop the bad guys, but if it’s good enough they may move on to an easier target.” –Paul Herbka

This quote simplifies a crucial truth, particularly when considering that almost half (47.4%) of all web traffic came from bots. These bad guys are constantly making efforts to break into your digital assets, and you definitely shouldn’t be the easiest target! 

Just as you lock your doors, your website deserves protection too. And there is a special kind of defender you can set against digital threats– Captcha. 

If you are used to browsing online, then you’ve already encountered captchas countless times. Captcha works to protect your website from fraud and abuse by deciding who to get in– humans or sneaky computer programs (robots)! Website owners use captchas like virtual gatekeepers to effectively look after their digital assets.

So, if you want your website to stay outta bad guys, you should also use those captchas. But which one, reCaptcha or hCaptcha?

In this battle of reCaptcha vs hCaptcha, we will discuss every aspect in-details that will help you decide which one is good enough for blocking troublemakers on your website. 

Let’s get started.

What is malicious bot activity?

Robots that start doing things they’re not supposed to do are malicious bots. They might mess up the site’s rules ignoring the site’s owner’s intention or even try to steal important data. We call these mischievous robots “bad” bots.

Now, some of these bad bots take it to a severe level and get involved in cybercrime. They might try to steal identities, take over accounts, and do all sorts of dark stuff. 

Let’s see some different types of malicious bot activities:

• Credential stuffing
• Content scraping
• Password cracking
• Inventory hoarding
• Spam web content
• Email harvesting
• Click fraud and more.

What does captcha mean?

The full meaning of Captcha is “Completely Automated Public Turing”. The primary function of Captcha is that it blocks frauds (Malicious computer programs) from registering or doing any abusive activities online. 

In simple words, a captcha is like a quick test on a website to determine if you are a real person or a computer program(Robot). To take the test and differentiate, it might ask you to do something EASY that humans can do effortlessly (but a nightmare for bots!) such as clicking a checkbox, typing characters, solving a puzzle, and many more that we will discuss in the following section. 

These simple tasks help the website ensure that you are a real person and not a sneaky robot trying to cause trouble. So, in a word, a captcha is like a “Digital Gatekeeper” who is on duty to let genuine people in and keep robots out. 

Different types of captchas

There are different types of captchas available that use different methods to challenge robots. Here are some typical captchas you can use:

• Image-based CAPTCHA: you need to select specific images that match a given description/criteria.
• Text CAPTCHA: you will see distorted/garbled text that you need to decode and type into a text box accurately.
• Audio CAPTCHA: you will need to listen to an audio clip containing spoken words or numbers and need to type in what you heard in a certain box. 
• Mathematical CAPTCHA: you need to solve a simple math problem.
• Slider CAPTCHA: drag a slider to a specific position or complete a puzzle-like action to prove you are a human.
• Checkbox CAPTCHA: you will be asked to tick a checkbox to prove you are not a robot. 
• NoCAPTCHA reCAPTCHA: A variation of reCAPTCHA where you simply need to check a box that says “I’m not a robot.”
• Invisible reCAPTCHA: This type of CAPTCHA runs in the background and uses behavioral analysis to determine if you are a human or a bot. 
• 3D CAPTCHA: you require to rotate or manipulate a 3D object to a specific orientation.
• Social Media CAPTCHA: you need to solve a challenge related to social media.
• Game CAPTCHA: you need to play a short game, solve a puzzle, or complete a mini-task.

Among these different types of captchas, you can use any of them as far as your level of need. 

Now let’s talk about its significance. You already have sensed why a captcha is important, here’s more to justify. 

Why Captcha is Important: differentiate bots and humans

In this era of vulnerable data security, it is crucial to distinguish between robots and humans for lots of obvious reasons. A robot can be programmed to perform automated tasks such as hacking, data scraping, spamming, and many more that can cause unimaginable trouble.

Here are some key reasons why a captcha is crucial:

• Protect your website from malicious activity: By identifying and blocking robots from the website you can protect your digital assets from potential threats like spamming, hacking, and the scraping of confidential data.
• Enhance user experience: By reducing spam and unwanted messages, blocking robots can improve user experience.
• Improve security: By hindering bot access to your website, captchas can increase overall site security.
• Account protection: Captcha helps prevent automated attacks on user accounts.
• Data Quality: Captchs can help maintain the quality of user-generated data that could distort analytics or pollute databases

So, the main point is that distinguishing between bots and humans is a must for your overall well-being online.

Till now, as we discussed captcha in general, let’s have our talk regarding reCaptcha vs hCaptcha.

What is reCaptcha?

reCaptcha is Google’s very own captcha technology. If you use the internet, you have probably encountered Google reCaptcha many times already. 

It’s usually free for many websites and applications, but enterprise users pay based on the number of captchas they are employing. 

To detect bots, reCaptcha can use multiple methods, including

• Checkbox: A website user must click on a checkbox to verify that they are human.
• Image selection: A user needs to select specific images from a group of images to verify.
• Audio challenges: Requires listening to an audio recording and transcribing the words or numbers to verify.

How does Google reCaptcha work?

Google reCaptcha examines website users’ behavior to determine if they are human or a computer program (Robot). When someone visits a website and if the website uses reCaptcha, the service gathers information about the users’ behavior like mouse movements, typing patterns, and other activities. 

These collected data are then processed by reCaptcha’s Risk Analysis Engine, which utilizes advanced algorithms to confirm if the user is a human or a bot. If the algorithm believes the user is a real human, only then it will permit access to the website. 

On the other hand, if the algorithm identifies the user as a robot, it will present them with a captcha challenge that prevents bots from entering the website directly. 

Moreover, reCaptcha employs a spam filtering system that is based on feedback from millions of users. The reCaptcha algorithm utilizes this feedback to become more accurate over time and enhance its power to differentiate between humans and robots.

Advantages of using reCaptcha

• Brand value is significant. People love to use Google’s services due to its immense popularity. 
• reCaptcha is compatible with major screen readers like ChromeVox, NVDA, etc for visually impaired users.
• Once the API is configured, users have the option to choose a client-side integration between reCaptcha v2 and reCaptcha v3.
• Best of all, it offers usage of up to one-million assessments per month for free.

Disadvantages of using reCaptcha

• China blocked Google and its services, so reCAPTCHA functionality is limited, affecting its widespread use in the world’s largest digital community.
• Implicit data labeling issues when engaging with reCaptcha tasks that often subconsciously contribute to Google’s machine learning initiatives. 
• Some reCaptcha images are low quality which makes it hard for visually impaired users. 
• Both reCAPTCHA v2 and v3 lack extensive features and support, with v3 being the more user-friendly version but costing some pennies. 
• Customization options are only available for enterprise-level users. 
• reCaptcha is often considered non-GDPR compliant.
• There is always a headache about privacy and data usage. 

In the battle of reCaptcha vs hCaptcha, now is the time to know about another player hCaptcha–

What is hCaptcha?

In case you’re wondering, the ‘h’ stands for human. hCaptcha is a popular alternative to Google’s reCaptcha. This captcha offers a free solution for non-enterprise customers. 

Usually, the hCaptcha requires site visitors to label images, which is somewhat obvious because hCaptcha’s parent company is an image labeling organization, and data vendors buy the labeled data fetched from the widget. 

Because of these manual procedures, hCaptcha uses less data than reCaptcha to operate its service, but hCaptcha also uses cookies. Each web user’s unique identification is stored in one of these cookies, which allows hCaptcha to track users across websites that use it.

How does hCaptcha work?

hCaptcha requires regular website visitors to manually complete an image classification task based on a series of images. The process is quite difficult because hCaptcha’s labeling tasks are often more difficult than reCaptcha. 

Enterprise users may use an invisible version of the captcha, but it still requires users to manually solve a puzzle if not enough user data can be collected to identify if the user is a human or a robot. 

Advantages of using hCaptcha

• hCaptcha offers potential user incentives for those who successfully complete a hCaptcha challenge.
• It is compliant with Section 508 and WCAG 2.1 AA for ensuring an inclusive experience for all users.
• It ensures a strong emphasis on privacy, prioritizing user data protection and confidentiality.
• hCaptcha allows customization using JavaScript API
• hCaptcha is available in all the countries
• Free to use for up to one million assessments per month
• There are pro plans for more features and capabilities.

Disadvantages of using hCaptcha

• Incentives and donations are only listed as part of the publisher plan, but absent in pro and enterprise plans. 
• Although hCaptcha claims compliance with Section 508 and WCAG 2.1 AA, image-based tasks may pose accessibility issues. 
• Due to some low-quality images, solving something can be more difficult. 
• The parent company of hCaptcha does not disclose which companies benefit from user image labeling.

reCAPTCHA vs hCAPTCHA: The Key Differences

In the realm of Captcha technology, reCAPTCHA, and hCAPTCHA are two prominent names. While their core purpose is the same, there are key differences between the two that are worth considering when you are deciding which one to use. 

Let’s explore the significant differences between reCAPTCHA and hCAPTCHA considering 7 factors.
