Hiding files, comments, information, or messages within other forms of media and sentences is known as Steganography. There are several different software packages that will perform this task for you. Many different kinds of organizations use this process for several different reasons. It is also used to pass information from one individual to another. The history of steganography has evolved from the Ancient Roman times. How it is used, and who uses it is what can determine if it is good or bad.
As stated earlier, the process of hiding information has been around since Roman times. Hiding information in Roman times was very simple. They would write text on stone tablets and pour wax on top of the message. This would hide the message so that it would not even be seen. The receiver would then scrape the wax off of the stone and read the message. It has probably been used in every war that has ever been fought. There are also several forms in which to hide a message, such as just using the first letter of words to spell out a message. Now it has evolved so that someone can hide information in a picture or video and send it over the internet. The receiver can then use the software and a passphrase to see the hidden message. This would be useful if someone would like to copyright or authenticate their work. It can also be used for communication between individuals and organizations. There are reports that persecuted religious minorities use steganography to embed messages for the groups within images that are posted to know Web sites.(1)( (Westphal)
