Google has announced in a blog post that it has bought reCAPTCHA, the service that prevents bots from various nefarious online activities by making internet users interpret squiggly words, something computers don't do too well. The price Google paid has not been revealed.

"We're happy to announce to everybody now that Google has acquired reCAPTCHA, a company that provides CAPTCHAs to help protect more than 100,000 websites from spam and fraud", says Google.

Google says it will be applying reCAPTCHA's tech "within Google not only to increase fraud and spam protection for Google products but also to improve our books and newspaper scanning process".

Promising the company is "committed to delivering the same high level of performance that websites using reCAPTCHA have come to expect", it seems it will be business as usual for the online security solution.
