Google buys ReCAPTCHA

Originally spun off from a research project of Carnegie Mellon University, reCAPTCHA protects 100,000 Web pages and spam fraud.

Google has increased its capacity optical character recognition (OCR) with the purchase of reCAPTCHA, a company that originated in a research project Canrney Mellon University and protects 100,000 websites of spam and fraud by distorted images that assumes that a machine can not understand.

From Google explains that CAPTCHA is designed for the human eye in order to prevent malicious programs get millions of email accounts to send spam. Google reveals a detail that is most CAPTCHAs offered by the company come from newspapers and old books scanned. Therefore it is difficult for computers to recognize these words because the ink and paper have degraded over time so that the company's technology can also be used to improve OCR processes to convert scanned images into plain text.

The technology can be used for text scanning projects on a large scale as Google Books and Google News Archive Search. Having the text version of a document is important because you can search plain text, export to mobile devices and display visually disabled users.

With the purchase Google says it will not only increase protection against fraud and spam from the company's products, but also improve the process of scanning books and newspapers.
