As an example, the duo demonstrates another item from the kit: a black-and-white bandanna printed with a blocky, digital pattern reminiscent of the common Arabic keffiyeh. Oliveira folds the bandanna and then hands me his iPhone. When I aim the phone's camera at the patterned cloth, a message appears instantly on the screen. When the cloth is folded a different way, another message appears.

Oliveira explains that unlike the ubiquitous QR Code, these patterns don't contain the messages themselves. Instead, each pattern is a hash—a number used to reference data stored elsewhere. When the pattern is scanned, the Backslash app looks up the value on a locally stored hash table. That way, only those who possess the hash table already can read the bandanna's hidden messages
