Google acquires ReCAPTCHA

Google has acquired a Carnegie Mellon University spinoff that seeks to cut down on spam and fraud at websites while digitizing books.


ReCAPTCHA offers simple word puzzles that users must solve when registering at a website or completing an online purchase. Computers can’t decipher the twisted letters and numbers, ensuring that real people and not automated programs are using the site.
