In the wake of NSA surveillance allegations, designer Sang Mun created the 'ZXX' font to trick surveillance robots. ZXX was built to subvert text-recognition software and make it unable to read your secret text. As a result, your correspondences stay safe from prying robot eyes.
The font works to thwart readers by employing Captcha-esque strategies. Each letter is disguised through extraneous noise that software has difficulty interpreting.
The secure typeface was named after the Library of Congress's label for books with "no linguistic content." Though the font is available for free and could be used, Sang created the project as art. Using the ZXX typeface itself is not a very effective text encryption strategy since the fonts are readily available and computers can adapt.
