In today’s modern world information is more abundantly available, can travel faster and plays a bigger role in society then ever. As such the control over information plays a more important role then before. Traditionally different types of cryptographic techniques have been used whenever information needed to be kept hidden except to a select few. However, classic cryptography has the obvious downside that it is apparent for a potential eavesdropper that information is being hidden, and that fact alone can be enough for him to act.
Linguistic steganography attempts to solve this problem by hiding messages in plain text, so that the encoded message looks like any normal piece of text, that is, not suspicious. In this paper I first introduce the reader to the fundamentals of linguistic steganography and secondly attempt to evaluate a specific method by constructing and testing a prototype system.
Results given by the prototype examined are found to be adequate, in the sense that it produces usable output most of the time. This paper thus concludes that linguistic steganography can, and most likely will, be a tremendous tool for secretive communication, provided it is used under correct circumstances.
