This scheme was designed to be segmentation-resistant, and it has been well studied and tuned by its designers over the years. In this paper, we analyse the security of a text-based CAPTCHA designed by Microsoft and deployed for years at many of their online services including Hotmail, MSN and Windows Live. The state of the art of CAPTCHA design suggests that such text-based schemes should rely on segmentation resistance to provide security guarantee, as individual character recognition after segmentation can be solved with a high success rate by standard methods such as neural networks. The most widely used CAPTCHAs rely on the sophisticated distortion of text images rendering them unrecognisable to the state of the art of pattern recognition techniques, and these text-based schemes have found widespread applications in commercial websites.
For example, some humans may be very quick at clicking on the checkbox, which could make it seem like a robot did it.CAPTCHA is now almost a standard security technology. The problem arises when the human movement becomes similar to a robot, and that is when you are given the what’s inside the pictures test to ensure you are not a robot. Of course, there are other factors and movements to note as well, but this basic difference is common. And a human would take time to drag the mouse and click on the checkbox and usually not directly in the middle. Usually, a robot software immediately moves the mouse cursor in the middle of the checkbox and click on it. Therefore, when you click on the checkbox the test follows your movement to understand whether it’s a human or a robot software.
The purpose of this test is to ensure that the person accessing the service is an actual human, not a robot. In this post, we will learn how this captcha test works and what can we do to pass it without having to answer what’s inside the pictures test. Thankfully, I have found a trick that seems to be working fine in passing the I’m not a robot test with a 100% success rate so far.
