Google Algorithm can read street numbers with over 90% accuracy, 99.8% accuracy with CAPTCHAs

In a paper published this week, Google researchers say that they've developed an algorithm that can accurately solve Google's own CAPTCHA puzzles... with 99.8 percent accuracy...

The new system was developed to help Google automatically analyze hard-to-read signs and house numbers photographed by its Street View cameras, allowing it to accurately match images with locations on a map. ... Despite being near perfect when it comes to CAPTCHAs — a feat that plenty of humans can't even manage — the new system's analysis of Street View imagery isn't quite as accurate, correctly identifying the text just over 90 percent of the time. When analyzing house numbers specifically, however, its accuracy jumps up to over 96 percent.

Era of the CAPTCHA is over

I hope you're not going to take that as an excuse to have an anti-spam system in place :wink2:

Good riddance.

Just because Google can crack their own CAPTCHA service doesn't mean it's still not an effective measure against spambots. I definitely get a lot more spammers on my PHP-based forums without a CAPTCHA than I do with a CAPTCHA, so it's working somewhat. I still get human spammers though, not much you can do about that unless they've been added to an antispam list like StopForumSpam, and your forum software is configured to block emails, IPs, and usernames that have been logged X amount of times in the SFS database.

Point is, the era of the CAPTCHA is far from over.

Uses the HTML5 Camera API. It asks the user to blink twice, and it lets you register. Depending on your stated gender in the registration form, it may ask you to do any number of actions to prove you're human.

Good idea, but what happens to users visiting the site from a monitor that does not have a camera attached? Perhaps a fallback system.

Well...
