Bot or not? Google reveals 'invisible' test to spot humans

Internet users are now well accustomed to the brief frustration of the CAPTCHA system – the quick tests that require you type distorted letters or check a box that says'I am not a robot' before proceeding. But now, Google is tapping into machine learning and advanced risk analysis techniques to spot potential bots without you even knowing it. This means the tests will be'invisible,' as the system will instead rely on distinct cues that let it know the user is a human, or alert it of a possible bot. Google is tapping into machine learning and advanced risk analysis techniques to spot potential bots without you even knowing it. The new'invisible' service will let human users through based on their interactions, eliminating the need for a dedicated test Instead of using CAPTCHA tests to determine if the user is human, the system will let the user's interactions speak for themselves. Using machine learning and advanced risk analysis, it will consider'the user's entire engagement with the CAPTCHA, and evaluates a broad range of cues that distinguish humans from bots.'
