INTRO
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.
BASIC UNDERSTANDING
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 i.e. 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 of th...

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’s 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’s ultrasounds became routine in Glasgow hospitals.
The dream that I most desire in life is to become a Diagnostic Medical Sonographer. I’ve always had an interest in the inner workings of the human body, but I also value life, and care for others, and my happiness is the happiness of others. Although this career has its bumps on the road just to see mothers face light up when they see the image of their unborn baby is such a breath taking experience. This all originated from going to one of my sisters’ ultrasound appointment that I ended up going to all my sisters’ ultrasound appointments. I believe becoming a diagnostic medical sonographer is something I can do because I have what it takes. Diagnostic medical sonographer is imaging modality that can work in conjunction with other imaging modalities
Do diagnostic Medical Sonographers actually help begin a new life? Yes, according to researchers they do help patients indicate any problems that there may be and what may be expected. This essay will talk about Diagnostic Medical Sonographers and everything it takes to become one and how to become successful as well as why they are important to our global community. Sonographer’s are also known as ultrasound Technicians, they are very important in the medical field because they help patients and physicians diagnose and treat diseases as well as other medical information. The following paragraphs will talk about the information of the Salary and also the Job Responsibilities. With the technicians continuously providing

Ultrasound Technicians are very valuable in the world of health care. Also known as Diagnostic Medical Sonographer, an Ultrasound Technician uses special machines and equipment that operates on sound waves to determine or diagnose medical problems for patients. There are specializations within this field in which some individuals explore. For instance, areas of specialization includes but not limited to; pregnancy, heart health, gynecology, and abdominal sonography. Although each specializing branch has its own distinctive function, they all involve probing the body to facilitate doctors with diagnoses.

Ancient Egyptian hieroglyphic writing is one the oldest and most interesting forms of written language developed. There is evidence of its use from before 3200 BCE and Egyptian hieroglyphs remained in use for over 3,500 years. The Egyptian name for hieroglyphs translates to “language of the gods,” although the term hieroglyph actually came from Greek words meaning “sacred carving,” which the Greeks used to define the writing found on Egyptian monuments and temples (Ancient Egypt, Hieroglyphics, n.d.).
James Madison once said “Knowledge will forever govern ignorance; and a people who mean to be their own governors must arm themselves with the power which knowledge gives.” To gain a better understanding of a society, one must gain knowledge of the needs and wants the citizens’ demand from the country’s representatives. In every country the needed to protect its citizens is the same. In some nations, security is a higher priority which causes sacrifices to be made to obtain an indefinite protection against all rivals. In Peter Singer’s essay titled “Visible Man: Ethics in a World without Secrets” he states that there is a way that governments can collect information by using technology; to allow more ‘openness’ and exposure as an increase of unknown surveillance that the public is not aware of. Singer’s essay also talks about how also with the rise of secrecy within politics; organizations such as ‘WikiLeaks’ and ‘Anonymous’ reveal to the world what is really going on within their privacy. Benefits come from both sides in a world where surveillance exists to the highest priority with or without privacy.
Hackers and terrorists have been using this form of technology for years. The United States governmental officials had suspected an attack on the United States for a period of time and thought the information to be hidden using steganography. Anyone can use and get access to steganographic materials. It's easy to download on numerous sights and no software is required. It's an easy and cheap way to keep information secure and undetectable. The number of steganography sites has doubled in the past two years (Kolata, F4). The United States government is also trying to place restrictions on encryption methods to prevent another catastrophic attack in the world such as the World Trade Center attacks. By having access to a private key the government would have unlimited access to secure information and crack codes all for safety reasons (USA Today). A " private key" is needed to decode any steganographic messages. Images are made up from a combination of an abundant of pixels (tiny dots).
Data encryption refers to the transformation of data into a structure that makes it unreadable by anyone without a secret decryption key. It ensures that messages can be read only by the planned recipient. Encryption is the procedure of obscuring information to create it unreadable without special information. Only organizations and individuals with an abnormal need for secrecy have actually made good use of it. Nowadays, encryption is one of the most important technologies for maintaining your privacy and the security of important information. This helps out greatly especially when E-Commerce is being used.
Before I even get into this, let’s be honest for the next five minutes. Oh come on, don’t deny it, we’re all curious. We’ve heard someone or the other talk about this, and we’ve been interested to find out what this elusive term actually looks like. We’ve secretly seen it in the depths of darkness in our room when no one is around, with just the light of the laptop for guidance. We’ve looked with gaping eyes at those CDs with the rather explicit covers that were being sold on that lorry at that particular crossroad, and we’ve wondered how exactly is it that people have bought them. If nothing else, we’ve all accidentally clicked that link in a side tab in our browser, or just by mistake reached one of those videos, and we’ve seen it through, before quickly shutting the window in shock. Come on, don’t lie. You’ve already clicked on the link to read this article, so might as well admit it.
Once a person is used to signing his or her signature, these nerve impulses are controlled by the brain without any particular attention to detail. It is evident that no two signatures of a person are precisely the same and some signature experts concludes that if two signatures of the same person written on paper were identical they could be considered forgery by tracing. According to [86] handwriting shows great variation in speed and muscular dexterity. Forgeries vary in perfection all the way from the clumsy effort which anyone can see is spurious, up to the finished work of the adept which no one can detect. Experience shows that the work of the forger is not usually well done and in many cases is very clumsy indeed. The process of forging a signature or simulating another person’s writing, if it is to be successful, involves a double process requiring the forger to not only copy the features of the writing imitated but
