Of course it’s not new, Google gets this a lot. This time the breach is Google’s program using CAPTCHAs to interpret blurred house numbers. If Google has ever asked you to enter a set of blurred numbers when answering a security query for a Google account, you’ve entered one of these numbers–therefore Google has made you part of the problem, citizen. Let the Guardian, in posh tones, explain:
The same image is presented to other Google users around the world at the same time. If enough people submit the same number, Google accepts they have accurately read the photo and are therefore not bots.
Traditionally these security checks – of which there are estimated 200 million a day – have involved typing blurred letters or words into a box.
