So captcha is something that we are all familiar with and we all have been solving for years. It is the primary mode of internet security and ever since it made a debut, it is free to be used by webmasters. They have been there from the late ’90s and started as the Turing tests and were found very effective against the bots where they came with mage recognition tests and the bots couldn’t identify any.
They got so famous that the anti captcha API had to be used to get the captcha solved. This is because over the years the spam technology has been improved a lot and to cope with them, the captcha had to be strong enough to get things done. But not every captcha requires anti captcha key to get the captcha solved. Some captcha can be solved with the blink of an eye and some will require you to use anticaptcha. Here are the Captcha types that have been using quite a lot around the internet.
Standard Word Problem
This is the initial form of Captcha used to differentiate between the computer and human user. The usual look like a square box with some letters twisted in a way that humans have to analyze and find out what they are Because humans have the natural ability to recognize images so they can understand this captcha easily.
However, some users with visual problems may find it hard to understand this captcha that makes it one of the most annoying Captcha types and they may have to resort to the anti-Captcha so they can complete the Captcha to get the things done.
Confident Image Captcha
A kind of Captcha where users will be provided with the series of images that they will have to find according to the description, and mind the fact that the images cannot be identified by the AI behind Captcha on its own as they just work according to the collected information by the most human interacted with the captcha type. This also means that if the most number of humans has marked the image of the dog as Ferrari then the AI will considered it Ferrari that can be a problem. Though the anti captcha API can be used to get rid of such Captcha those without Captcha solving service can be in trouble.
Time-BasedJquery Captcha
This is a type of Captcha that comes with a time limitation. This means that the user will have to complete the captcha within the given time. This is perhaps one of those Captcha types where users can easily get stuck. Because not all of them can type equally and this makes it hard to complete in the first or second attempt. However, If you take help and use the anti captcha key then chances are you can get that Captcha did without any hassle.
Honey pot Captcha
A Captcha type that usually stays hidden from the users. Unlike other Captcha that keeps appearing during internet surfing, this Captcha is designed by programmers under the page with empty boxes those human users cannot see it. Usually, the bots are designed to mark every tick box available. Human users cannot see the honey pot so they can continue on the page or website without ever using anticaptcha. Bots can see those boxes and they will tick those boxes. The monitoring Ai behind will detect that unusual moment and it will cause an instant ban.
Match Question Captcha
This is another type of common Captcha where users will be provided with some math equations that they will need to solve to continue further. And no, these equations are very basic such as “2+2=” or “4+6=”. Yes, ironically these basic equations cannot be solved by advanced users thus makes it easier for humans to complete this Captcha type and even without using any help of anti-Captcha. However, sometimes the equations can be too tough to handle for no reason and even the human users give up on that and they have to use anti captcha API.
No Captcha reCaptcha
This was introduced in 2014 and it is also a free product of Google. Unlike captcha, the reCaptcha doesn’t require anyone to complete tough puzzles and equations. It can be placed in any corner of the page where the user will have to tick mark it and that it. However, Spambots are programmed to tick in the center so the unusual behavior can be detected and the bot users can be banned to spam can significantly be reduced. And because of its convenience, you don’t have to use any anti captcha key to complete it.
Game-Based Captcha
A Captcha that isn’t very common but still very effective against the spambots. This is a type of Captcha that requires users to play some game which in this case is drag and drop the ball, drag this mouse to cheese or drive the car to the point. They are very easy and fun Captcha types that users can do without using any anticaptcha service. Because bots aren’t advanced enough to interact with this kind of Captcha so the spam can be eliminated easily.
Tic-Tac-Toe Captcha
The name says it all. An easy to solve Captcha for anyone who has played tic-tac-toe so and it can be completed without anti-captcha. The rule is simple, win against the AI and Captcha is completed. This is also a fun Captcha that is effective against spambots because of its nature and performance.
Jquery Slide
This is a type of Captcha that requires the user to activate it by sliding a button. This is perhaps one of the simple forms of Captcha and it is also good enough to do well against the spambots.
There are several other types of Captcha developed for the one single reason that is stopping spam. However, they can be hard sometimes and if you find it hard as well then use services like anticaptcha to get the things done easily.
