Over the years, Google has utilised a number of methods to distinguish between human and bots on the web. Its take on the CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) test, known as reCAPTCHA, has required you to transcribe distorted words, confirm Street View addresses or simply just tick a box. Soon, you won’t need to do the hard work, because Google’s making the system invisible.
Using a combination of machine learning and advanced risk analysis, Google has updated its system to detect user habits without dedicated interaction. When you arrive on a web page, the controls should disappear and serve the relevant content.
