Privacy, Security, and Artificial Intelligence: CAPTCHA no longer Secure? Vicarious, a San Francisco based A.I. company claims to have created a new algorithm than can read CAPTCHA images  just as well as humans. With advancement in image processing, signal processing, and machine learning techniques, sound and image based CAPTCHAs will certainly have to evolve to keep up with security demands.

 The start-up Vicarious, based in Union City, Calif., claims it has come up with artificial intelligence (AI) software that reads images nearly as well as humans and can crack a CAPTCHA 90 percent of the time. If the claims are true, they could signify a breakthrough in building AI that is indistinguishable from human cognition—at least when it comes to helping computers identify and understand images. Vicarious calls the architecture its AI system is based on a “recursive cortical network,” meaning it is modeled along the line of the human neocortex—the brain’s gray matter that processes information. This approach allows AI software to learn new things from a few examples, much as a human child comes to understand the world by learning to recognize what he sees and figuring out how the images are connected. Software Firm Claims Breakthrough in Computer Vision Will Lead to Better AI – Scientific American
