CAPTCHA: Completely Automated Public Turing Test To Tell Computers and Humans Apart

CAPTCHA = Completely Automated Public Turing Test To Tell Computers and Humans Apart

A CAPTCHA is a type of challenge–response test used in computing to determine whether the user is human. The term was coined in 2003 by Luis von Ahn, Manuel Blum, Nicholas J. Hopper, and John Langford. The most common type of CAPTCHA was first invented in 1997 by two groups working in parallel.

They could be easily solved by humans, but they become challenging for machines to solve, therefore preventing programs from abusing online services and occupying internet resources.

Using Convolutional Neural Networks, the CAPTCHA tests could be solved automatically at high efficiency. Current approaches of high accuracy CAPTCHA recognition can be structurally complicated.

CAPTCHA Recognition

As a solution to the automation problem due to a CAPTCHA, we have developed an API web service that caters automated CAPTCHA solving to solve a CAPTCHA.

How it works?

Simple, you upload or send us the CAPTCHA through API and we solve it and give you the answer. All in a protected API web service. See below for the steps on how CAPTCHAs.IO works.

  1. Using our API web service, upload the CAPTCHA image either by form or base64 format. On how to upload using HTML form please refer to our document here https://api.captchas.io/document/#html.
  2. From the API endpoint https://api.captchas.io/in.php you will recieve a text based or json based answer that looks like this; OK|91239572 or {'status': 1, 'request': 91239572}. The request value is the CAPTCHA ID which you will use to get the CAPTCHA solved answer using the https://api.captchas.io/res.php API endpoint.
  3. Now that we have the CAPTCHA ID, we will now try to get or retrieve the CAPTCHA answer or token. This is done by sending an HTTP request to https://api.captchas.io/res.php with data parameters as key={APIKEY}, action=get, and id={CAPTCHAID}.

The service is https://captchas.io and has a subscription package plan of which starts $22 USD a month. Other packages are available in case you want to scale up.
