A Simple Watermark: Patchwork VI. Current Work in Watermarking VII. Conclusion VIII. Works Cited Introduction 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...

... To generate the watermark an input frame is scanned to compute the , which represents the 128-bit hash value MD5 cryptographic function. The watermark is nothing but the bits of digital signature of hash value and secretes key . In the initial stage we extract the frames from the video sequence. The watermark generation process shown in Fig. 2. is explained in following steps: 1. The hash value is initialized to some arbitrary fixed value. 2. The position of the Last Non Zero (LNZ) level for each block is stored so that it can be used while extracting the watermark. 3. The value of the JPEG quantization matrix corresponding to LNZ is set to 1 so that after embedding the watermark bit the pixel value vary by plus or minus 1 instead of plus or minus . This modification in quantizer value leads to less distortion in video signal. Fig. 2 Watermark Generation 4. The value of the JPEG quantization matrix corresponding to LNZ is set to 1 so that after embedding the watermark bit the pixel value vary by plus or minus 1 instead of plus or minus . This modification in quantizer value leads to less distortion in video signal. 5. Set the Least Significant Bit (LSB) of LNZ to zero. 6. Update the hash value by applying the hash function to its previous value and all the coefficients in block. 7. This process is repeated for all the blocks of video frame. After all blocks are scanned the Digital Signature Algorithm (DSA) is applied on the final hash value...

...Digital piracy is making up profit from illegal copying and reselling music, videos, software videogames and other digital media which requires genuine. In 2005, loses of legal media and software industry from digital piracy was $200 billion (DSTI/IND (2007). Also, Oberholzer-Gee (2010) indicates that 60% of World Wide Web broadband busy by consumers’ video, game and music sharing. To avoid this issue intellectual proprietors use various methods. In this paper is shown methods to dodge problem of digital piracy. There are two ways to protect legal digital content from piracy. Firstly, there is indirectly impact to society, where manufacturers are producing additional equipment like guitars for game “Guitar Hero” and forwarding special social services where people can play with each other via internet, so while people playing, system is checking license (Goel, 2010). In addition, companies perform free software with fewer options than paid software. Moreover, some organizations such as Free Software Association and Open Source agitation, which advert spreading software for free have helped to grapple with problem of expensive software and companies that gain from this, for example, Microsoft (Hill, 2007). Secondly, there is direct impact on users, where companies and internet providers use methods which impacts directly on users such as blocking peer-to-peer connections between users and web-sites where users can download pirated software. Furthermore, closing the sources of...

...International Journal of Computer Applications (0975 – 8887) Volume 9– No.7, November 2010 Steganography- A Data Hiding Technique Arvind Kumar Assistant Professor Vidya College of engineering, Meerut, India Km. Pooja Vankateshwara institute of computer Science and technology, Meerut, India ABSTRACT Steganography is the art of hiding information and an effort to conceal the existence of the embedded information. It serves as a better way of securing message than cryptography which only conceals the content of the message not the existence of the message. Original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable. In this paper we will discuss how digital images can be used as a carrier to hide messages. This paper also analyses the performance of some of the steganography tools. Steganography is a useful tool that allows covert transmission of information over an over the communications channel. Combining secret image with the carrier image gives the hidden image. The hidden image is difficult to detect without retrieval. This paper will take an in-depth look at this technology by introducing the reader to various concepts of Steganography, a brief history of Steganography and a look at some of the Steganographic technique. In steganography, the possible cover carriers are innocent looking carriers (images, audio, video, text, or some other digitally representative code) which will hold the hidden information...

...patients' sensitive medical records, it's always important how one also deals with medical images that should also be kept private. Health Insurance Portability and Accountability initiated on April 14, 2013 by the federal government, establishes all relevant standards to address the issue of privacy protection. The HIPAA requires for integrity and confidentiality in all of current, previous and future from hospitals, doctors, and other relevant professionals. In an era where digital technology has become of major importance, there is a series of medical images that can now be kept in digital format and become quite easy to retrieve, store and preserve. Watermarking – An Essential Aspect for the Protection of Medical Images A. Ethical reasons and relevant legislation define Medical Information Assurance & Watermarking Medical directions. USA's HIPAA and Europe's EC 95/46 Directive are the major legislations defining relevant directions. When dealing with medical information records, thus, which involve a series of clinical examinations, diagnoses, and EPR images, three major security attributes should be considered: • Confidentiality: only authorised users can view and evaluate medical information; • Availability: Scheduled accessing periods should be set when entering the information system containing the medical data; • Reliability: The information should be examined by authorised people and not changed by unauthorised ones. Additionally, it’s important for a...

...Teleputers: Communication and Information New technology for communication is growing rapidly. Health care systems are taking advantage of new communications to make organizations more efficient, effective, and user friendly. These systems have superior advantages, but with the many advantages noted there are also disadvantages. The health care system has to decide if the financial impact of changing its system is beneficial in the long run. Because technology is always updating, incorporating a new communication system may only be useful for a short time. Immense growth in medical knowledge and technology spawned an era of specialization in which doctors focused on particular aspects of health called, ‘”specialization” (DuPre, p. 38). This paper will be discussing a new technology termed as “teleputers.” Teleputers are small mobile devices used as a computer, phone, and entertainment. In 1999 researches predicted that people would use teleputers to conduct research, play games, surf the internet, and transfer information (DuPre p. 321). Many people use smart phones. A smart phone is a mobile, hand held computer that is used as a phone, planner, clock, game and entertainment system, and much more. How is this important in health care communications? Health care systems sometimes have supportive groups to convey information through telephones and computers. These are virtual communities (Du Pre, p. 182). Having “teleputers” makes sharing information easier and more convenient...

...History of Cryptography Developments in cryptography | Period | Development | 2000 BC | In Egypt, hieroglyphics were used in inscriptions. | 500-600 BC | Hebrews used the atbash method for encryption. In this method, each letter of the alphabet mapped to a different letter to hide the true meaning of a word. | 487 BC | The Spartans used the scytale for encryption – messages were written on paper wrapped around a wooden rod. The paper was then unwrapped and sent. The recipient could read the message only by wrapping this paper on a rod of the same length and diameter. | 100-44 BC | Julius Caesar used an encryption method similar to the atbash method. He shifted each letter of the alphabet by a fixed number of places to send encrypted messages. | 1379 | Gabrieli di Lavinde developed the nomenclator. | 1466-1467 | The first polyalphabetic cipher was invented, which was much stronger than the nomenclator. | 1518 | Johannes Trithemius invented a steganographic cipher in which each letter was represented as a word taken from a succession of columns. | 1553 | Giovan Batista Belaso introduced the use of a passphrase as the key for a repeated polyalphabetic cipher. In 1563, Giovanni Battista Porta introduced the digraphic cipher and classified ciphers as transposition, substitution, and symbol substitution. | 1585 | Blaise de Vigenere developed the polyalphabetic substitution cipher. William Frederick Friedman published a book on cryptography, and is known as the...

Tamil Nadu,India. Abstract- Steganography is the art of hiding information in ways that avert the revealing of hiding messages.Video files are generally a collection of images. so most of the presented techniques on images and audio can be applied to video files too. The great advantages of video are the large amount of data that can be hidden inside and the fact that it is a moving stream of image. In this paper, we proposed a new technique using the motion vector, to hide the data in the moving objects. Moreover, to enhance the security of the data, the data is encrypted by using the AES algorithm and then hided. The data is hided in the horizontal and the vertical components of the moving objects. The PSNR value is calculated so that the quality of the video after the data hiding is evaluated. Keywords- Data hiding, Video Steganography,PSNR, Moving objects, AES Algorithm. I.

...the development of printing press technology, this concept was slightly changed as now copying was regarded as a theft from the original content. This made the writers of the past to make copyright laws that would protect the individual work The three systems defined in this paper deal with copyright issue of digital media. The system defined here are the ones that are in bad need of a proper copyright scheme as these digital media content are the ones that are most effected by the piracy and copying issues. The copying of any of these contents results in the decrease revenue for the author, hence discouraging the author for producing a better kind of media for later use. The first system defined is the Giovanni, which is digital watermarking technology for audio media. The basic idea of this company is to produce audio that is watermarked with waves that are inaudible to the human ear. Giovanni maintains the functionality of copyright targets by keeping archives and provide maintenance to the author. Yet, it does not restrict any access of the eligible person. The second system proposed is the Content Scrambling System, which is embedded in DVDs and DVD players. This system provides copyright by embedding encrypted region codes into the DVDs that allows the DVDs to be played in only the available regions encoded in the contents of the DVD. The DVD player then...
