PUBLIC MARKS with tags typography & privacy

ZXX, as the typeface is called, comes in four flavors, each exploiting a different weakness in existing OCR tech. The “Camo” style obscures letterforms with camofalgue-style blobs. “Noise” splatters them with digital graffiti. “X’ed” just lays a big, crisp X over each letter, and “False” adorns each letter with another tiny, secondary letters. With each–or better yet, a mix of them all–Mun shows how it’s still possible to print a message that can’t be snooped on by some camera peeking over a shoulder.

The name ZXX comes from the Library of Congress' Alpha-3 ISO 639-2 -- codes for the representation of names of languages. ZXX is used to declare No linguistic content; Not applicable. Free Open Type Font to open up governments.
