Why Privacy Matters Even if You Have 'Nothing to Hide'

From The Chronicle of Higher Education:

When the government gathers or analyzes personal information, many people say they're not worried. 'I've got nothing to hide,' they declare. 'Only if you're doing something wrong should you worry, and then you don't deserve to keep it private.'

The nothing-to-hide argument pervades discussions about privacy. The data-security expert Bruce Schneier calls it the "most common retort against privacy advocates." The legal scholar Geoffrey Stone refers to it as an "all-too-common refrain." In its most compelling form, it is an argument that the privacy interest is generally minimal, thus making the contest with security concerns a foreordained victory for security.

The nothing-to-hide argument is everywhere. In Britain, for example, the government has installed millions of public-surveillance cameras in cities and towns, which are watched by officials via closed-circuit television. In a campaign slogan for the program, the government declares: "If you've got nothing to hide, you've got nothing to fear." Variations of nothing-to-hide arguments frequently appear in blogs, letters to the editor, television news interviews, and other forums. One blogger in the United States, in reference to profiling people for national-security purposes, declares: "I don't mind people wanting to find out things about me, I've got nothing to hide! Which is why I support [the government's] efforts to find terrorists by monitoring our phone calls!"
