In the United States, privacy is a right under the fourth amendment to the U.S. Constitution.
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
In the United States, the right to protect yourself is outlined in many places, but the most cited is probably the second amendment to the U.S. Constitution.
A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.
and in 2008, the Supreme Court expanded that right to,
an individual right to possess a firearm unconnected with service in a militia, and to use that arm for traditionally lawful purposes, such as self-defense within the home.
While firearms have been the focus of second amendment rights, there are other weapons an individual may use to protect and defend his or her right to privacy. One of the most powerful weapons available is encryption. Learn what cryptography is, learn how to use it responsibly, and protect yourself online.
