Steganography is the practice of hiding secret messages in seemingly innocuous documents such as pictures, articles, or shopping lists. The practice dates to the 5th c BCE, when early practitioners concealed information under the wax of wooden writing tablets or on the tattooed scalps of slaves. As technology evolved, so did steganography; and today, information is often hidden in computer files.
