Why Privacy Matters Even if You Have ‘Nothing to Hide’ By Daniel J. Solove

Most attempts to understand privacy do so by attempting to locate its essence—its core characteristics or the common denominator that links together the various things we classify under the rubric of “privacy.” Privacy, however, is too complex a concept to be reduced to a singular essence. It is a plurality of different things that do not share any one element but nevertheless bear a resemblance to one another. For example, privacy can be invaded by the disclosure of your deepest secrets. It might also be invaded if you’re watched by a peeping Tom, even if no secrets are ever revealed. With the disclosure of secrets, the harm is that your concealed information is spread to others. With the peeping Tom, the harm is that you’re being watched. You’d probably find that creepy regardless of whether the peeper finds out anything sensitive or discloses any information to others. There are many other forms of invasion of privacy, such as blackmail and the improper use of your personal data. Your privacy can also be invaded if the government compiles an extensive dossier about you. Privacy, in other words, involves so many things that it is impossible to reduce them all to one simple idea. And we need not do so.”
