Interesting and easy-to-use alternatives to CAPTCHA

Robots looking to do malicious things are always a danger on the Internet. The damage or inconvenience they have caused to people is sufficient to justify websites look for ways to block their entry. That’s why CAPTCHA was invented – it was an extra line of defense that kept those pesky bots out. That said, many found them bulky and often difficult to perform properly.

This is why we have compiled some of the best alternatives to CAPTCHA which work just as well and are easier for users to do:

What is Captcha?

CAPTCHA stands for Fully Automated Public Turing Test and it was designed to be able to distinguish real humans from robots. It is often a question of choosing certain objects from a group of images or of copying a series of distorted and stretched letters. These are relatively difficult for computers or robots to do, but are easy for most humans.

They are often used for:

  • Keep polls accurate.
  • Prevent bots from signing up for services.
  • Prevent fake comments or create fake accounts.
  • Prevention of inflation of banknotes.

The problem is, however, that sometimes CAPTCHAs are difficult to perform. Some people just can’t answer them correctly and end up getting very frustrated. Plus, they don’t apply to some browsers, leaving some websites vulnerable. This has led many website owners or app builders to use alternatives to CAPTCHA which are less complicated and work fine with their platforms.

Alternatives to captcha:

Below are some of the most common and popular alternatives to CAPTCHA currently available online:

1. The honey pot trap

It is one of the most popular alternatives because it is invisible to the user. A honeypot trap is written on the CSS of a website and it will trigger the validation process to fail if anything is entered in its scope – usually a bot.

Basically there are hidden hidden fields on a form that serve as traps. These fields are not seen by humans and therefore cannot be written. A spam bot, however, cannot tell the difference and will try to fill in all possible fields. When the fake field is filled in, the system recognizes it as a bot and automatically disallows verification, thus preventing the bot from going any further.

This completely eliminates the use of CAPTCHA or user testing. That being said, there are a few issues with this method. For example, it may not work if users have CSS turned off. Many users also have browsers that have autofill features, this can mean that an ordinary person can be mistaken for a bot because the browser itself tries to fill in the trap fields.

2. Gamification

This type may still be a problem for some users, but will definitely be fun for most. In this alternative, a game is introduced instead of a CAPTCHA. All users need to do is drag the correct items on the screen into a box. It can also be other games like crashing or matching types. Normal bots don’t have the power to distinguish one item from another, but a human can – this allows for a non-CAPTCHA verification method that also adds a layer of interactivity to the site.

This, however, might not work for all websites in a stylistic sense. There are also those who might find this type of verification too difficult or too painful to perform every time.

3. Competency assessment question

Simple logic, grammar, or math questions are also a fun way to prove that people really are people. These questions are often so simple that a child could answer them but are impassable for most bots. If done right, they can also provide your site with a sense of humor and user interaction that visitors enjoy.

This of course depends on what you are looking to be for your users. This alternative is certainly easy enough to identify humans from computers, but the simplicity of the questions may be too silly for you or the user to take seriously.

4. Cursor

If you are looking for one of the simplest CAPTCHA alternatives possible, use the slider. The user just needs to swipe a bar left or right to prove they are human. The sliding bottom remains invisible to robots but is easy to see and slide for a human. It also applies to mobile versions of your website or apps.

CAPTCHA or more complicated alternatives can be difficult to achieve with the smaller screens of many cell phones. All of this requires a sliding bottom and an instruction for the user to slide in order to continue.

5. Check box

For the latest and possibly the easiest of all CAPTCHA alternatives, all you need to do is ask the user to check a box to prove that they are not a robot. Not a lot of thought or effort is required for this. It might seem like too easy a task to cheat on, but just checking or unchecking a box is proof of a choice robots don’t have.

The only requirement for this step is that you are clear with the instructions. This is all the more necessary since many people do not know what spambots are.

Conclusion

These are the main alternatives that you can use as opposed to CAPTCHA. They will certainly serve their purpose. Well, as long as they’re used correctly. It’s also important to note that at the end of the day, all of these types of user checks are used for the same purpose: to prevent bots or automatic users from disturbing our systems. Many of them can be tedious or take too long to complete, but they are essential in keeping the internet as secure as possible.

It is a great desire to make verification easy for users, but the user will be even more secure if you make sure that bots or other malicious elements are kept away for good.
