Can this font help protect your privacy? —
Former NSA contractor Sang Mun's ZXX font is designed to disrupt Optical Character Recognition (OCR) -- the software used by Google and others to scan books or physical documents.

Character assassination —
South Korean designer Mun designed four fonts: 'Camo' which adds camouflage-like patterns over letters, 'Noise' which overlays each letter with dots, 'Xed' which puts a neat X across each character, and 'False' where a small letter is placed beneath a larger false one.

Letter writing —
Research Professor Matthew Green says 'the idea of building puzzles that only a human can solve ('reverse-turing tests') is a very neat area in CS research,' but that in his view organizations such as the NSA would have no real trouble dealing with these fonts if they wished to.

Font of all wisdom? —
Mun says that he understands the criticisms, but says that his fonts are meant to spark dialogue and make people think about their own online security: 'ZXX is a call to action, both practically and symbolically, to raise questions about privacy.'
