Google has acquired reCAPTCHA. Captchas are the images that are used to prevent spam and reCAPTCHA is the famous open source technology used to provide these captchas. Over 100,000 websites worldwide is using reCAPTCHA now. As written on every reCAPTCHA form "stop spam, read books", the captchas you enter actually helps to digitize books and newspaper. Google will also use reCAPTCHA for the same purpose but this time reCAPTCHA will be used for Google Books and Google News Archive Search.
According to Google :
"This technology also powers large scale text scanning projects like Google Books and Google News Archive Search. Having the text version of documents is important because plain text can be searched, easily rendered on mobile devices and displayed to visually impaired users. So we’ll be applying the technology within Google not only to increase fraud and spam protection for Google products but also to improve our books and newspaper scanning process."
So over 100,000+ captcha forms will now digitize books and newspapers to make them web searchable. This makes alot of sense or may this is another example of Google's power on the web? :P Google says that reCAPTCHA’s technology improves the process that converts scanned images into plain text, known as Optical Character Recognition (OCR).
How reCAPTCHA Works?
Do you know how actually reCAPTCHA works? Every reCAPTCHA contains two words i-e control word (one with known answer) and one where the OCR software wasn't quite sure what the word was. Once a certain number of users have solved the suspicious word with the same result, it becomes a control word itself and the OCR software can learn this word. Isn't it interesting... :)
