Prove you’re HUMAN: Real-time Captcha technique relies on human answers to unusual questions

In a happy marriage of old Captcha and new biometric techniques, researchers have devised a new verification methodology called Real-Time Captcha. It presents real-time puzzles that will throw artificial intelligence for a loop and protect the accounts of human users, reported a ScienceDaily article.
Real-Time Captcha is a logical evolution of current biometric techniques based on facial photos or video feeds of the user. It’s designed to foil machine learning and image generation software that have adapted to now-standard security systems.
Like current image-video biometric systems, Real-Time Captcha asks users to look into the camera of their mobile device. The new addition is a Captcha that appears on the screen with a random question that a human can answer much faster than an artificial intelligence could…. more
