CAPTCHA—or “Completely Automated Public Turing test to tell Computers and Humans Apart”—is a security feature that can prevent the use of websites that may be unlawful. It is a type of test that is located on websites where a user needs to put in a series of letters and numbers or click certain parts of a picture in order to complete a task. That task might be purchasing a product, opening an account, posting a review, or any other kind of task. Web developers use this on sites to make sure the being using the website is indeed a human with good intentions.

Often times, the word-solving image is distorted, which makes it difficult to read. While its purpose is to fool a robot or computer from being able to read it, it can also sometimes be difficult for humans to read. In fact, some people feel that CAPTCHAs can inhibit disabled users from being able to access certain parts of a website. While CAPTCHAs may not be able to prevent all types of spam on the internet, it certainly does a good job. Without it, there would be so much more negativity and frustration happening all over the web.

CAPTCHA is important to many internet empires in order to prevent a robot from manipulating services. Some services that robots can manipulate would be opening too many accounts, getting a lot of sensitive information, or posting too many messages, which can hinder web analytic results.

There are some people out there who might want to solve CAPTCHA codes in order to participate in some of the above-mentioned acts on a website. As with anything in life, there are two sides to every story. Some companies make their money solving CAPTCHA codes and selling them to people who are interested in using them. Solving CAPTCHA is useful for people who want to manipulate websites opening multiple accounts, sending spam messages, and trolling the internet.

There are various types of CAPTCHAs that can be used on websites. It is important to understand the classes so that when you are shopping around for a CAPTCHA solving company, you can make an informed decision based on what kind of CAPTCHAs you are looking to solve. Here are some of the different types you might come into contact with. They all have some pros and cons, of course, and that will be discussed as well.

Math Problems

One popular form of CAPTCHA is a simple math problem added to a site. For example, a user may have to solve and enter the answer for a math problem such as “4+6”. While it might be hard to believe, this can be difficult for a robot to solve and enter an answer for, which makes this type of CAPTCHA secure. One pro for this type of CAPTCHA is that it is simple and usually easy to read, which helps the user have the ability to solve it quickly and move on with whatever task they are trying to accomplish.

It is both effective for the user and secure for the website. A con is that it is not as sophisticated as some of the other types of CAPTCHAs, so it may not feel as secure. It may be perfect for websites such as WordPress or other HTML sites.

Word Problem

Another effective type of CAPTCHA is a simple word problem for the user to decipher. This type is similar to the previously mentioned math problem CAPTCHA where a user has to answer a simple question. It might be offered in the form of writing a word in all capital letters and asking the user to retype it. It could also give a user multiple words and ask them to type in the last one, or it could list multiple words, one that is displayed in a color and ask the user to type in the color. In order to solve this CAPTCHA, a user must be able to follow the directions carefully, or the security feature will not allow the user to move on.

A benefit of this type of CAPTCHA is that it may be great for users who are visually impaired and might have a difficult time solving some of the more visual CAPTCHAs. One downfall of these is that as robots become more and more intelligent, they will be able to solve these kinds of word problems. While word problem CAPTCHAs are secure, there is always an exception to the rule.

Social Media Sign In

A foolproof way to offer CAPTCHA is to have a user sign up or sign in using their Facebook, Instagram, Snapchat, Google, or other social media account. This means the user is verified to sign in without having to enter in any information. An advantage of having a website linked to social media accounts is that bots are unable to sign in because they don’t have a social media account to use. A disadvantage may be that humans are hesitant to have all their information linked because of personal information and security.

While this is a different type of CAPTCHA, it doesn’t replace using other security features on a website, but it does help determine a human from a bot. Another advantage of using this strategy is that it can help a user sign onto a website in a quicker time than it would take having to input all the information separately.

Time-Based

This type of CAPTCHA records the amount of time it takes a user to fill out their information on a form. If it is a human, it will probably take a bit of time to fill out a form. Bots, on the other hand, will fill out a form almost instantaneously. This is a great type of CAPTCHA to use for sites like WordPress. The advantage is that it is pretty easy to determine whether or not it is a human user or a bot. The downside is that having someone fill out a form every time they want to make a comment, post a message, or perform a task, the user might find this frustrating and time-consuming.

Honeypot

This type of CAPTCHA involves a bunch of hidden fields on a screen. The interesting part about this one is that it is not the human that is tricked, rather the robot. Bots are able to see these fields on the websites, but humans are not. In essence, it tricks the bot into filling out these fields that humans are not able to see. When the bot fills it out, the website knows it is not a true human user. One of the greatest benefits of this type of CAPTCHA is that it is unknown to humans, meaning the user experience is not affected by annoying games or having to input lots of information. Chances are, you have visited a website and come across a Honeypot CAPTCHA without even knowing it.

There is always the possibility that it won’t work with some Bots who are smart enough to know they are being tricked. For example, Safari autofills forms, so the Bots are more likely to get around this. When creating a website, all the developer has to do is add the hidden field, give it any kind of name and use CSS to make a rule “display:none” which will hide it from the human users who are filling out the given form. The Honeypot method is a unique type of CAPTCHA that makes it very different from the others. It also does not require an extra add-on to the website as it is easy to install upon development.

No CAPTCHA reCAPTCHA

The No CAPTCHA reCAPTCHA method is a type of CAPTCHA that has been created by Google. It has only been around since 2014 but has already made its place on the internet. The point of it is to determine a human user from a robot by the behavior when presented with a simple task. The task that is presented to the user is to click on a box indicating, “I am not a robot”. This method can also be used with phone and apps, but would involve clicking on the box with the finger, rather than the mouse. The CAPTCHA tracks the movement and figures that if the box is checked directly in the middle, it is a robot.

Robots are very methodical, so it is easy to determine by the behavior. Humans would most likely not click directly in the middle but in some other area of the box. This method has been incredibly accurate, thanks to Google. If this first test fails, there is a backup where the user will then be asked to type some combination of numbers or letters. The downside is that it can create a frustrating experience for the user if they have to do the test twice.

Invisible reCAPTCHA

This is a version of the No CAPTCHA reCAPTCHA that was updated by Google recently in 2017. In this case, the CAPTCHA is invisible to the user in order to create a better user experience than the previously mentioned method. There is no text or numbers to enter, no box to check and no form to fill out, but it seems to work. In fact, it is not clear how exactly it works, but it does use a method of monitoring the user’s behavior while they are on the site. It may very well be similar to how the No CAPTCHA reCAPTCHA learned about the difference between human Bot behavior based on where they click. While it seems to be successful as of now, there is always the chance that robots will eventually be able to outsmart it.

Confident CAPTCHA

This type of CAPTCHA is based on images. The user must follow some kind of direction that has to do with images. For example, they might be instructed to, “Click on each image that has a street sign in it”. One of the benefits of this is that it has a 96% success rate. A downside might be that it could be frustrating for the user. If the task is not performed correctly the first time, they will have to go through the process again with a different image. For this type of CAPTCHA, another benefit is that it can be turned into a way to make money. Website owners can use this CAPTCHA as a way to advertise, which can earn them some money.

Sweet CAPTCHA

Sweet CAPTCHA is similar to confident CAPTCHA. It involves asking the user to perform some kind of task where they are moving or matching items to one another. An example would be showing an image of a suitcase with items next to it. The CAPTCHA will ask the user to place the shirt into the suitcase to verify their human identity. The upside to this one is that these types of tasks are not something a robot can perform accurately, so it is very good at determining an identity. The con to this type of CAPTCHA might be that it can interfere with user experience. If the user makes a mistake, they will have to perform the task again. This can become frustrating for the user.

Biometrics and the Future of CAPTCHA

If you own an iPhone or another type of Smartphone, chances are, it has asked you to set up a fingerprint or another kind of security feature. While this isn’t yet an actual CAPTCHA, it is a very important security feature that could be the future of CAPTCHA. It allows for complete security because everyone has unique fingerprints. By using your fingerprint to sign into your phone or an app, it ensures that you are the only one who can get the information needed. This could be something that websites require in the future to complete tasks like sign up for an account, post messages, or making a purchase. It could certainly be beneficial because it would prove a user’s identity. A downside could be that it might cause issues for accounts.

With the many different types of CAPTCHA, a website owner will have to determine which type is best for their website. This also means that to solve CAPTCHAs, there are many different types that a person who solves them has to know about in order to successfully solve them for users.
