The end of captcha buttons?

Why we might not have to tick a box to prove we are not a robot for much longer.

What is a Captcha button?

We’ve all had to do it at some point, whether it is ticking the box, picking out all squares with road signs on are trying to copy out some almost-incomprehensible letters and numbers. These Captcha checks, as they are called, are used to stop automated bots accessing and using websites. They are often used on things like contact forms to stop spam or phishing emails, or on sites selling concert ticks to stop people having automated bots set up to buy all the best tickets. You could also see them if you were to enter incorrect log in details on a site, to ensure that you are not a robot trying automated attempts.

They can also be used to help train artificial intelligence algorithms such as Google’s AI. For example if the AI system was not able to recognise a house number in a photo taken by a streetcar view, the photo might be added to its Captcha system to get a human input.

What’s new?

Google’s new system is able to remove any puzzle for most people by tracking how they interact with a website; it analyses how people have interacted with different elements of the site such as the ‘submit a form’ button. If there is any behaviour that is deemed to be ‘suspicious’ a more traditional Captcha box will still appear though.
