Reddit introducing the next generation of CAPTCHA
Comments(2)
Could this be the next generation of CAPTCHAs being introduced by a social networking site? I definitely think so with similar techniques being used in the world of Computer Security
Reddit is one of the hottest sources for what’s new and popular on the web. Reddit gives editorial control to people who use the site and not to those who run it. The users get to decide which stories are popular and vote them to the front page.
A CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. Computers are unable to solve CAPTCHAs so anyone entering the correct solution is presumed to be human. The most common type of CAPTCHA including that used by Reddit requires a user to type the letters of a distorted image. Sometimes this CAPTCHA is enhanced with the addition of a sequence of numbers also distorted.
Technology now exists to read some types of CAPTCHAs. So the latest generation of CAPTCHAs add more distortions such as highlights, shadows or random line segments with a gradient background etc. Below is an example of a CAPTCHA you would see if you submit any stories or articles to Reddit
However, last night while surfing on the Internet Super highway, I found a really interesting article, which I wanted to submit to the social networking sites including Reddit. So, when I try to submit this story, image to my surprise where instead of seeing the regular CAPTCHA, I see a new form of CAPTCHA which Reddit is trying to introduce.
