The idea of data surveillance can sometimes feel distant, as if it’s not actually affecting you directly. But in a new project called Seen, communications designer Emil Kozole points out how our everyday language can become prone to secret surveillance. Seen is a typeface that comes preloaded with a set of trigger words that organizations like the NSA or GCHQ often scan for when sifting through data. When a user types one of the words, the font will automatically cross it out, notifying the writer that they’ve entered taboo territory. It’s an effective way to illustrate just how easy it is to become targeted.
