There are a couple of interesting aspects to this story. I was fascinated to learnt that AI character recognition has advanced to the point that the standard CAPTCHA test is no longer a reliable way of differentiating between humans and automated posters. This obviously has significant implications for the ability to digitise wider and wider ranges of physical data through the current generation of optical character recognition,

But the other striking element of the story, as an insight into the current state of software capabilities, is the way in which the replacement for CAPTCHA is going to work. The back end of the test, running without the need for conscious intervention by the user, is taking data from the entirety of the users interaction with the site in question, assessing a complex range of behaviours to establish with confidence whether the user is human or automated.

Admiration for the capabilities of the software aside, this is a dramatic reminder of the substantial quantities and range of data that are captured about each of us, every time we interact with the vast majority of websites. Worth remembering, perhaps, the next time you click to accept a privacy policy without reading it.
