The growing popularity of the Internet and multimedia methods have sparked an ever increasing interest in hiding data with in digital media (Wang). Many of the methods that have been used to protect copyrighted materials such as audio, video, images, and text, have focused primarily on watermarking. However embedding data within data has also proved useful for concealed communication, or stegonagraphy. This paper will address in further detail what stegonagraphy is, and the various techniques that are utilized. Stegonagraphy is a form of hidden communication that literally means covered writing Niklasson. The message itself is left in plain view for all to see, but goes unnoticed because the very existence of there even being a message is secret. One popular expression used to describe this method is hidden in plain sight, experts refer to this as Security through Obscurity Duraiswamy. This is of course in distinction to cryptography where the message is actually scrambled, and the data left virtually unintelligible encryption to the eavesdropper even though the existence of a message is often times known beforehand. It is also important to note that watermarking and stegonagraphy differ as well. Stegonagraphic information must never be evident to a viewer unaware of its presence. Modern stegonagraphy should only be detectable if secret information is known a secret key, whereas this key feature is optional when referring to watermarking. Also compared to watermarking, stegonagraphy has drawn less attention until recently, as computer specialists, signal-processing researchers, and multimedia product vendors concerned about information security have recognized that illicit use As an ultrasound technician sonographer I will have the ability to see dangerous defects within the human anatomy and begin a lifelong profession with many benefits. The Ultrasound was first invented in the early 1900 and was surprisingly not used to produce photos of a fetus. In 1917 Paul Langen a marine life scientist used a form of ultrasound equipment in his attempt to detect submarines. After many failed attempts at using high frequency sound waves Dr. Ian Donald and his team in Glasgow, Scotland invented the first ultrasound machine in 1957. Dr. Donald even tested his machine on patients within a year of completing the invention, by the late 1950 ultrasounds became routine in Glasgow hospitals.
