Google to buy fraud-proof technology company for digital books

Beijing time September 17 (AP)--Google announced in Wednesday the acquisition of the Carnegie Mellon University incubation website fraud-prevention tool company reCAPTCHA to crack down on spam and fraud in books when digitized, the Associated Press reported. The terms of the agreement were not disclosed.

reCAPTCHA provides a few simple word fans that users must fill out when they sign up for a Web site and complete online shopping. If the letters and numbers are wrong, the computer is not recognized, ensuring that the keyboard is a true user, not an automated installation of the software. Unlike other word-puzzle games, reCAPTCHA's material comes from existing books, which are produced when the book is digitized.

Google is working on a major project to digitize and publish Books Online, mainly by scanning every page of the book and using the optical character recognition system (OCR) to make text searchable. However, OCR does not necessarily recognize worn-out, faded, and cluttered text, so it is sometimes necessary to manually input.

Luis von Ahn, a professor of computer science at Carnegie Mellon University, said that reCAPTCHA was best suited to Google, and that the reCAPTCHA project was Louise Fangan from the outset, so it was easy to understand that reCAPTCHA eventually found a home in Google.

Google, which set up offices in the university campus in 2006, has also been involved in another development project led by Fangan, calling online users to play online games that make computers more intelligent. One of the games is ESP, and Google has licensed the game with the name Google Image Labeler. In the game, the player will see a picture and need to guess the words that other players might use when describing the picture. This game can improve the image search function.
