Invasion of privacy has three forms.

Intrusion Upon Seclusion

You may not take photographs or record a person in his or her home without his or her consent. This legal concept sometimes extends to other private places, to photos of the inside of the person’s home, or to "hidden camera" or "hidden microphone" use anywhere.

Private Facts

Details of an individual's sexual relationships, personal hygiene, contents of personal letters, etc., are off limits to the news media, except when such facts are "newsworthy."

False Light Publicity

Inventing quotes or fictional events to portray a person falsely to the public, or using photos out of context to imply scandalous activity, is unlawful.
