Steganography () is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity. The word steganography is of Greek origin and means "concealed writing" from the Greek words steganos (στεγανός) meaning "covered or protected", and graphei (γραφή) meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography disguised as a book on magic. Generally, messages will appear to be something else: images, articles, shopping lists, or some other covertext and, classically, the hidden message may be in invisible ink between the visible lines of a private letter.

The advantage of steganography, over cryptography alone, is that messages do not attract attention to themselves. Plainly visible encrypted messages—no matter how unbreakable—will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal. Therefore, whereas cryptography protects the contents of a message, steganography can be said to protect both messages and communicating parties.

George Mason IV (December 11, 1725 – October 7, 1792) was an American Patriot, statesman and a delegate from Virginia to the U.S. Constitutional Convention. Along with James Madison, he is called the "Father of the Bill of Rights." For these reasons he is considered one of the "Founding Fathers" of the United States.

Like anti-federalist Patrick Henry, Mason was a leader of those who pressed for the addition of explicit States rights and individual rights to the U.S. Constitution as a balance to the increased federal powers, and did not sign the document in part because it lacked such a statement. His efforts eventually succeeded in convincing the Federalists to add the first ten amendments of the Constitution. These amendments, collectively known as the Bill of Rights, were based on the earlier Virginia Declaration of Rights, which Mason had drafted in 1776.

On the nagging issue of slavery, Mason walked a fine line. Although a slaveholder himself, he found slavery repugnant for a variety of reasons. He wanted to ban further importation of slaves from Africa and prevent slavery from spreading to more states. However, he did not want the new federal government to attempt to ban slavery where it already existed, because he anticipated that such an act would be difficult and controversial.
