Privacy laws of the United States

The privacy laws of the United States deal with several different legal concepts. One is the invasion of privacy, a tort based in common law allowing an aggrieved party to bring a lawsuit against an individual who unlawfully intrudes into his or her private affairs, discloses his or her private information, publicizes him or her in a false light, or appropriates his or her name for personal gain. Public figures have less privacy, and this is an evolving area of law as it relates to the media.
