The nothing-to-hide argument is ubiquitous. This is why I wrote an essay about it 10 years ago called “I’ve Got Nothing to Hide,” and Other Misunderstandings of Privacy , 44 San Diego Law Review 745 (2007). It was a short law review piece, one that I thought would be read by only a few people. But to my surprise, this essay really resonated with many people, and it received an unusually high number of downloads for a law review essay. I later expanded the ideas in the essay into a book: Nothing to Hide: The False Tradeoff Between Privacy and Security (Yale University Press 2011).
