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 their private affairs, discloses their private information, publicizes them in a false light, or appropriates their name for personal gain. Attempts to improve consumer privacy protections in the U.S. in the wake of the 2017 Equifax data breach, which affected 145.5 million U.S. consumers, failed to pass in Congress.
