It's no news to anyone that's reading this that the meteoric rise of the Internet in recent years has significantly increased the availability of all forms of media. Nowhere is this more obvious than in the realm of commercial musical recordings, where Napster and other internet-based distribution systems have made incredible volumes of musical content widely available, all without the consent of the music's originators. This situation, though, is not unique to the music industry, as photographers, filmmakers, and other content-originators all have the same problem to varying degrees. The solution, and even the need for a solution, to this problem of copyright infringement is still a topic that is open to great debate, but there is no debating the fact that some interesting and novel technology has been designed to help. Digital image watermarking, the practice of secretly embedding a piece of information in an image, is one of the more interesting of these technologies, and deserves some consideration. It is the purpose of this paper to give the reader an overview of watermarking and the diverse benefits that it offers. We begin with a brief history of watermarking and then go on to describe the basic components of any watermarking system, different uses for and characteristics of watermarking systems, types of attacks that watermarks are designed to defend against, all followed by a simple example of a watermarking system. We then conclude with an analysis of this watermarking system and an overview of topics of current research in watermarking.
History
Digital image watermarking is actually a derivative of Steganography, the ages-old practice of covertly transmitting a message from one party to another, typically used by governments and spy organizations. The earliest recorded use of such a method is mentioned in the Histories of Herodotus, where Histiaeus used the scalp of a slave to convey a secret message through hostile territory in the hopes of inciting a revolt against the Persians (Katzenbeisser, 3). The slave's head was shaven and tattooed with the secret message. After sufficient time had passed that his hair had regrown, the slave was sent on his mission, passing through Persian territory without arousing suspicion. When he arrived at his destination, his head was re-shaven to reveal the message.
Further examples, both in fiction and in history, can be found in more modern times. In Mother Night, author Kurt Vonnegut writes about a fictional World War II spy, Howard W.

One of the newest, most exciting and innovative ways to get music these days is not in the mall and not at a huge mega-sized electronic store, it's not even by a mail order CD club. It’s the computer. It sits conveniently on a desk and now allows access to every imaginable genre of music, twenty-four hours a day, rain or shine, snow or sleet, in the comfort of your own home. Technology is changing the way we listen to music. Now downloading a Mp3 from the Internet is a lot easier than going to the store and buying an overpriced CD. A near CD quality digital recording of music, Mp3s are digital computer files compressed to make them readily available over the Internet. It seems the high prices, new technology, and availability are causing most music lovers to turn to this new form of music media to combat their expensive addiction to compact discs. It has become so simple to search out and download music that more and more people are finding it favorable to just copy their music to a recordable CD (CD-R). That would mean people could, from their own home, create illegal copies of the copyrighted material at or near industrial compact disc quality. Further adding to consumer accessibility, manufacturers now produce portable MP3 players , so now the need to buy CD-R’s is eliminated and you can just...

This paper describes various forms of DRM (Digital Rights Management), the DMCA (Digital Millennium Copyright Act), and methods of bypassing the afore mentioned subjects. Different forms of transmission of DRM protected material also has a direct relationship with what kind of files are protected by the DMCA and will be discussed. This paper will also discuss how law makers are attempting to halt illegal music sharing and how these attempts are in vain.

Literature can be based on a myriad of plots. From a realistic fiction story to science fiction and aliens attacking earth, there are a multitude of possibilities. Many times the topic of the literature is based on some part of the author’s life. The short story, “The Red Convertible,” by Louise Erdrich, is a piece realistic fiction that has elements that parallel Erdrich’s life. This story outlines the relationship of two brothers, Lyman and Henry. They have a strong relationship, but after Henry comes back from the Vietnam War things change. “The Red Convertible” is a prime example of how authors write to express their feelings and make sense of life events. Ultimately, Louise Erdrich has perfected the art of writing a fiction story in an autobiographical way by relating events in her life such as her heritage, the death of her eldest son, and the suicide of her husband to those written in “The Red Convertible.”
The world religions of Islam and Christianity may have their differences to the naked eye, but when you take a closer look into their histories similarities arise. They both went through transformations that had drastic impacts on the way they were controlled and the way that the religion was taught to the followers. Christianity and Islam have both experienced splits between their members due to the fact that followers thought that their beliefs were the correct way to practice the religion. While these transformations are long in the past, the splits that have occurred within each religion continue to have lasting effects on Islam and Christianity to this day.

When choosing an author for my paper, I chose international suspense because I am very interested in foreign relations and the technology of modern day war. I have read stories by Edgar Allen Poe, with suspense and vivid imagery, which reminded me of Clancy's work. I decided to choose Tom Clancy because of his talent to weave such realistic tales of international suspense. Clancy creates the scenes in his books with such detail, it makes the reader feel like he/she is there. My first choice for this paper was Dr. Suess, but because he has passed away, I had to keep looking. I knew very little information about my author before writing this paper. I had read two of his books, but had no real knowledge of his personal life or past history. Tom Clancy, a successful American author of international suspense, has captured his love of military and technology and profitably employed it in the books he writes.

Along with the development of a file format (MP3) to store digital audio recordings, came one of the new millennium’s most continuous debates – peer-to-peer piracy – file sharing. Internet companies such as Napster and Grokster became involved in notable legal cases in regards to copyright laws in cyberspace. These two cases are similar in nature, yet decidedly different. In order to understand the differences and similarities, one should have an understanding of each case as well as the court’s ruling.
However much Islam and Christianity would seem to share common ground, the discussion is not complete without noting the parallels between this two that have taken center stage. Some of the remarkable differences as they try to answer deep life complexities arise in the areas of religious practices by both their adherents and the clergy (Dorothy 13-28). “There is also a stark contrast to the belief system subscribed to, means of salvation, scriptures”. The most prominent difference present concerns the belief of life after death and practices of depicting the metaphysical
Both Islam and Christianity believe in one god but they praise them in different ways. With the Islamic god being Allah and the Christian god being Allah and the Christians god being Jesus there religion was founded differently. The Islamic word for god is Allah which means the god of Islam (the one and only universal god/ creator of the universe). With Muhammad the last messenger and prophet being directed by Allah to spread his message around so the people can worship Allah. Muhammad went around for years gathering followers, Muhammad became more than a prophet with his wife by his side. He wanted equality for both the poor and the rich. For the god of Christianity is considered to be the son of god who was sent down to earth to spread out his message. Jesus
