Stenography is a scientific technique that allows secure communication without revealing the intended message to a third party. This form of passing messages has been used for a long period. The Greek people are among the scholars who pioneered the use of the technique. The Greeks used secret writing to pass messages from one individual or group of people to the next without letting a third party know the intended message even if such a party saw it. The term stenography was initially a direct translation of the Greek work for undisclosed writing Silberstein-Loeb, 2009. Stenography has been passed from one generation to the next. It has found application in many areas including the military and the diplomatic communications. Presently, stenography means any process that can lead to the hiding of messages within another object. When hidden, this message becomes unapparent to observers who see a different image or writing that does not make sense to them. The earliest application of this form of communication and information protection includes the First and Second World Wars where the armed forces used stenography extensively to pass messages to their colleagues behind battle lines and/or resistance within a given country and region. This paper examines the meaning of stenography, its history, and its current use. Besides, it shows how it differs from watermarking. It also examines the available stenography detectors and the areas where they are applied. Several authors have looked at the history of stenography and its use. Most of them have discussed its relevance in the military and in the current information age. Some of the earliest writers who wrote about Stenography as an art in communication include Johannes Trithemius who lived in Germany in the in the late 15th century (Judge, 2001). According to Judge (2001), Johannes described the art of writing and communicating with the spirits. In his work, Trithemius is said to have described several ways of hiding messages in writing (Judge, 2001). After the analysis of Johannes’ works, researchers found that there were hidden messages in the works. Dr. Ernst Paper as one of the researchers managed to get the hidden messages Judge, 2001 Many other works of art were meant to hide the intended messages to the audience, including the works of Mary Queen of Scots Judge, 2001. Some of the normal writing materials that have been examined in the past also contain significant forms of stenography
