CAPTCHA is security system created and developed to prevent Bots from accessing websites. This security system allows users to prove to be human by recognizing some patterns, distorted type in text or signs which are impossible for machines to complete correctly. This method becomes super successful to overcome the spam and bots from visiting and accessing the data or website. It’s a highly secured and advance way where different questions has been asked my AI to identify the real humans, and don’t allow the bots for visiting sites.
But, as we know nothing is a permanent solution. A lot of research in the past had proved to beat the CAPTCHA security system. Finally, researchers came up with Artificial Intelligence method to crack CAPTCHA.
Researchers used neural networks to learn what a CAPTCHA was and then to foil systems that used them. This is made to identify humans and give them permission to access the site, CAPTCHA is programmed for the same purpose.
However, cracking CAPTCHA was a difficult task as it required the system to crunch millions of examples to be proficient. Most of the examples and puzzles are made for humans, and only a real human can pass through it.
‘TechXplore’ reported that a new system called a recursive cortical network developed by the researchers at Vicarious-a California-based Intelligence firm could crack CAPTCHA easily after studying just a few number of samples.
Nodes are created to keep new information and are placed in each neural network. With the help of nodes, a network is created and is used to deal with the data.
After the process is learned, the results of the solution go back to the software and its being used again and again until a solution is reached. And once the solution is reached, the CAPTCHA fails to identify the real human and allow the bots to visit websites.
Researchers have used recursion in their techniques which was used to solve mazes. This technique allows them to reduce the learning curve of their software to a great extent and can crack the CAPTCHA system efficiently.
Researchers said to crack Google’s reCAPTCHA up to 67%, they just need five training steps. This is really surprising that highly secured and advance CAPTCHA can be cracked easily using bots. However, the internet world has taken this seriously and they are on move to advance the CAPTCHA to another advance next level.
