![]() A sample on hCaptcha’s website asks users to click through 9 to 27 images and select those which show a train. Users might not immediately welcome the replacement, however, because for all the difference behind the scenes,the tests that hCaptcha poses can be very similar to Google’s. “In our case,” says Prince, “that would have added millions of dollars in annual costs just to continue to use reCaptcha for our free users.” In the past, that value exchange was enough to keep Google’s tools free, but recently the company added an enterprise tier for corporate users who make more than a million calls a month, charging undisclosed fees. The tool was developed in part by the Guatemalan entrepreneur Luis von Ahn, who used a similar idea to create the first version of the language-learning app Duolingo. This helped Google’s image recognition software to tell the difference between, say, cats and dogs, and later taught the company’s self-driving cars and mapping vehicles how to recognise street signage. The first version asked users to transcribe hard-to-read words from scanned books, while later versions used similar technology to get people to label images. Google’s reCaptcha had been free for so long because, as well as testing whether a site visitor is a robot, it uses humans to do menial tasks. The tool has a wider range of tests than reCaptcha, including one asking users to draw a box around a specific object, or to identify the correct label for a picture.

Google’s introduction of charges for the service has prompted Cloudflare, a little-known firm that protects around 12% of the internet from bot attacks, to seek an alternative. ![]()
