I'm proposing the phrase

Data is naked without encryption

as a catch phrase to help get non-technical people to appreciate the need for encryption. They may have heard and repeated the "I've got nothing to hide" meme without realizing the irony of saying that while wearing clothes. This phrase references the clothing rebuttal to the 'nothing to hide' idea (which I sometimes express as "Then why are you wearing pants?") but brings it back around to data instead of leaving it in awkward personal territory, and also offers constructive advice (adopt encryption) instead of just being judgmental.

I haven't done many catch phrases over the years, but who knows, maybe this one will catch on.
