Implementing Negative and Positive Captchas in Rails

You know the drill: those ***** little boxes that pop up when you try to submit a form or sign up for an account, asking you to prove you’re not a robot by typing in some jumbled-up letters or numbers. But what if we told you theres a way to make captchas more fun and engaging? Introducing negative and positive captchas!

Negative captchas are the opposite of traditional captchas instead of asking you to type in a series of characters, they ask you not to do something. For example: “Please don’t click on any of these buttons.” Or, “Do not enter your email address here.” This might seem counterintuitive at first, but it actually makes sense when you think about it by asking users to actively avoid certain actions, we can prevent spam and other unwanted submissions without making them jump through hoops.

Positive captchas, on the other hand, are designed to be more engaging and interactive. Instead of just typing in a series of characters, you might have to solve a puzzle or answer a question related to the content on the page. For example: “Which animal is known for its long neck?” Or, “What’s the capital city of France?” This not only makes captchas more fun and interesting, but it also helps users remember what they were trying to do in the first place (like signing up for a newsletter or submitting a comment).

So how can we implement negative and positive captchas in Rails? Well, there are several gems out there that make this process much easier. One popular option is reCAPTCHA, which offers both traditional captcha boxes as well as more advanced options like invisible reCAPTCHAs (which don’t require any user input) and reCAPTCHA v3 (which uses machine learning to determine whether a submission is spam or not).

Another option is Google’s own “No CAPTCHA” reCAPTCHA, which uses advanced algorithms to distinguish between human and bot submissions without requiring any user input. This can be especially useful for forms that don’t require much interaction (like contact forms) since it eliminates the need for a traditional captcha box altogether.

Of course, there are also plenty of other options out there depending on your specific needs from simple text-based captchas to more advanced image recognition systems. The key is finding a solution that works best for you and your users, while still providing enough protection against spam and unwanted submissions.

So next time you’re building a form or signup page in Rails, consider adding some negative and positive captchas to make the experience more engaging and interactive who knows, it might just help prevent those ***** bots from ruining your day!
