What is CAPTCHA?
CAPTCHA stands for Completely Automated Public Turing Test which helps the server to identify computers and humans.
CAPTCHA is one such tool that you can use to differentiate between real users and automated users (such as bots).
CAPTCHA provides challenges that are difficult for computers to perform but comparatively easy for humans.
For example, identifying enlarged letters or numbers , or clicking in a specific area.
Why is CAPTCHA used?
CAPTCHA is used by any website that wants to ban the use by bots.
Apart from this, CAPTCHA is used in many places for the server to recognize computers and humans, that is, to understand the difference between real users and bots.
Why and where are CAPTCHAs used?
- Maintaining Voting Accuracy – CAPTCHAs can prevent voting from being skewed by ensuring that every single vote is entered by a human.
- Limiting Registration for Services - Services can use CAPTCHAs to prevent bots from spamming the registration system to create fake accounts . Restricting/Banning account creation prevents wastage of resources of a service and reduces the chances of spam .
- Preventing Ticket Inflation – Ticket systems can use captcha to limit scalpers from buying large numbers of tickets for resale. It can also be used to prevent false registration of free events.
- Preventing False Comments – Captcha can prevent bots from spamming message boards, contact forms or review sites. The additional step required by CAPTCHAs may also play a role in reducing online harassment through inconvenience .
How does CAPTCHA work?
CAPTCHAs work by providing information for a user to fill out.
“ Traditional Captcha ” provide a distorted or overlapping characters and numbers that a user has to submit there through a form field.
The distortion of letters made it difficult for bots to fill in the text and prevented access until the characters were verified.
This captcha type depends on human potential to generalize and recognize novel patterns based on variable past experiences.
In contrast, bots can often only follow set patterns or input random characters. This limitation makes it less likely that bots will correctly guess the correct combination.
Since the introduction of CAPTCHA , bots using machine learning have been developed. These bots are better at identifying traditional Captcha with trained algorithms in pattern recognition .
Due to this development, new captcha methods are based on more complex tests. For example, reCAPTCHA requires clicking in a specific area and waiting for a timer to expire.

Types and examples of CAPTCHA?
Although there are 6 types of CAPTCHA , but Mod CAPTCHA comes in three main categories-
- Text CAPTCHA,
- Image CAPTCHA
- and Audio CAPTCHA.
1. Text CAPTCHA
Text CAPTCHA is the basic way humans are verified. These CAPTCHAs can use known words or phrases or random combinations of numbers and letters.
Some text-based captchas also include a change in the capitalization of words.
Captcha presents these characters in a way that is isolated and requires filling. Separation can include scaling, rotation, distorted characters.
It can also include overlapping characters with graphic elements such as color, lines, background noise, arc or point.
This separation provides protection against bots with inadequate text recognition algorithms but can also be difficult for humans to fill in.

Techniques for creating text-based captchas include:
- Gimpy - It selects 850-words arbitrarily from the dictionary and provides those words in garbled form.
- EZ-Gimpy - This is a version of Gimpy that uses only one word .
- GIMPY-R - It selects random letters, then warps them and adds background noise to the characters. So that no bot or system tool can copy or detect it. Only humans could read and understand it.
- SIMERD HIP - It selects random letters and numbers , then warps the characters with arc and colors.
2. Image CAPTCHA
Image based CAPTCHAs ie Image CAPTCHAs were Devloped to replace text-based CAPTCHAs .
These CAPTCHAs use recognizable graphical elements, such as pictures of animals, shapes, or scenes.
Typically, image CAPTCHAs require users to select photos that match a theme or identify photos that do not fit.
You can see an example of this type of CAPTCHA below. Note that this defines the theme using images instead of text.
Image CAPTCHAs are generally easier for humans to fill than text CAPTCHAs .
However, these tools create specific access issues/problems for users with poor eyesight.
For bots, image CAPTCHAs are more difficult to fill than text because these tools require both image recognition and semantic classification.
3. Audio CAPTCHA
Audio CAPTCHA was developed as an option that provides accessibility to users with poor eyesight.
These CAPTCHAs are often used in combination with text or image-based CAPTCHAs .
Audio CAPTCHA presents an audio recording of a series of letters or numbers that the user then fills out.
They rely on CAPTCHA bots which are not able to separate the relevant characters from the background noise.
Like text-based captchas, these tools can be difficult to fill for bots as well as humans.
4. Math or Word problem
Some CAPTCHA tools ask users to solve a simple math problem such as "3+4" or "18-3".
The intention is that it will be difficult for a bot to identify the question and formulate its answer.
Another type is a word problem, which asks the user to type in the missing word in a sentence, or complete a sequence of several related words.
These types of problems are accessible to users with poor eyesight, but they can also be easy for bad bots to solve.
5. Social Media Sign In
A popular alternative to captcha requires the user to sign in using a social profile such as Facebook , Google or Linkedin.
User details will be filled automatically using the Single Sign On (SSO) functionality provided by the social media website
It's still disruptive/solvent, but it can actually be easier for users to complete than other forms of CAPTCHA . An added advantage of this is that it is a convenient registration tool.
6. No CAPTCHA reCAPTCHA
This type of captcha, which is known for its use by Google , is much easier for users than most other types.
It "मैं रोबोट नहीं हूं" (I’m not a robot)provides a checkbox saying that users need to select i.e. click inside that checkbox.
It works by tracking users' activities and identifying whether page clicks and other user actions resemble human activity or bots.
If the test fails, reCAPTCHA provides a traditional Image Selection CAPTCHA , but in most cases the Checkbox Test is sufficient to validate and recognize the user.

In addition to letters, some captcha codes require you to enter a number or a word that refers to pairs of images. Some other captcha frequencies require you to hear a certain phrase or word and type it in.
To generate the captcha code number, an experimental number is generated which you have to type. By typing this number, you can login to the site or fill out any other online form.
What is captcha example?
Here are some captcha examples:
- Text Captcha – In this you need to type the letters given in a short message. Example: “Type the letters below to login: a2Bc5d”
- Image Captcha – In this you need to identify and type the letters or numbers given in a small image. Example: An image would say "Type the letters in this image" and the image would say "B2uG7".
- Calculation Captcha – In this you have to perform a calculation related to a number and type the answer. Example: “8-3=?” The answer will be “5”.
- Sound Captcha – In this you will hear a sound and you have to type a word or number based on that sound. Example: "You're listening: What number is between two and three?" The answer will be “4”.
