CAPTCHA, the commonly employed security tool used by many websites to differentiate between humans and bots, isn’t completely impenetrable. Google has created an algorithm that can read and answer CAPTCHA fields with 99.8 percent accuracy, ZDNet reports. Developed by the Google Street View team, the algorithm was designed to help recognize characters on storefronts and street signs in blurry images. The algorithm is able to read 90 percent of street numbers, according to Google.
