...Information Hiding – Steganography Steganography Types and Techniques Abstract— Information hiding has been one of the most crucial element of information technology in recent years. Unlike Cryptography, Steganography does not only keep the content of information secret, its also keeps the existence of the information secret. This is achieved by hiding information behind another information. This paper gives an overview of Steganography and its techniques, types, and also its advantages and disadvantages. Keywords-component; steganography; information hiding; security; confidentiality; techniques. INTRODUCTION Steganography help hides the fact that communication is taking place by hiding some information behind another information thereby making the communication invisible. The origin of the word “steganography” is from the Greek words “steganos” and “graphia” which is interpreted as “covered” and “writing” respectively thereby defining steganography as “covered writing”. Steganography and cryptography are both part of information hiding but neither alone is without flaws. The goal of steganography is defeated once the hidden message is found or noticed even while still in the original message (carrier). For safely transmission of hidden messages or information in steganography, multimedia files like audio, video and images are mostly used has the carrier or cover source. METHODOLOGY The Methodology used for this paper is based on the...

...International Journal of Engineering Trends and Technology- Volume3Issue3- 2012 Hiding Messages Using Motion Vector Technique In Video Steganography P.Paulpandi1, Dr.T.Meyyappan,M.sc.,M.Phil.,M.BA.,Ph.D2 Research Scholar1, Associate professor2 Department of Computer Science & Engineering, Alagappa University,Karaikudi. 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.

...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...

...Avishek Raychoudhury Dept. of Computer Sc. & Engg, University of Calcutta 92 A.P.C. Road, Kolkata-700009, India ABSTRACT Technique for hiding the data of images has been proposed in this paper. At the source, hidden (target image) is encoded within another image (cover image). Firstly, the cover image and the target image can be adjusted by resize function. Secondly, only the final encrypted image i.e. cover image and target image is sent over the network. This image is finally decoded at the receiver end. Received results are encouraging from practical point of view. keys, the relative entropy between encrypt and one specific decrypt key Yusuk Lim, Changsheng Xu and David Dagan Feng, 2001, developed the web based authentication system. In case of watermark embedding system, it is installed in the server as application software that any authorized user, who has access to server, can generate watermarked image. The distribution can use any kind of network transmission such as FTP, email etc. Once image is distributed to externally, client can access to authentication web page to get verification of image [2]. Min Wu and Bede Liu, June 2003, proposed [3] a new method which manipulates “flappable” pixels to enforce specific block based relationship in order to embed a significant amount of data without causing noticeable artifacts. The hidden data can then be extracted without using the original image and can also be accurately extracted after high quality printing and scanning...

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 proof to exist that there is a direct link between the patient and his/her corresponding medical information and nothing else that could change this connection should interfere. Medical Information Systems (MIS) secure that the above named attributes exist by adopting five relevant security principles: availability, integrity, confidentiality,...

...problems in the society? I think the best example of both personal and family problems that is at least a result of problems in the society is a lack of respect. There is a lack of respect for people towards each other and the homes of families. Common courtesy has completely gone out the window somewhere along the line. Page 49 2. Choose a magazine photo and analyze its content from one of the perspectives described in this chapter. Then analyze the photo from another theoretical perspective. How do your insights differ depending on which theoretical perspective is used? I chose a magazine photo that shows a little boy in between his parents, hiding behind his mother and slightly looking up at his father. According to the perspectives in chapter 2 this looks to be a little of exchange theory due to the child hiding behind his mother and the slight look at his father. This also looks like it could involve attachment theory as the child looks to have...

...eye. Steganography has a number of nefarious applications; most notably hiding records of illegal activity, financial fraud, industrial espionage, and communication among members of criminal or terrorist organizations. This was the technique used by terrorists involved in 11 September 2001 demolition of World Trade Centre [12]. The misuse of the technology cannot be blamed on the technology itself but it totally depends upon the users of the technology. It is the inner conscious which covers the human being. If we follow our moral ethics and values and give respect to our culture we can prevent misuse of...

...Cryptographic Tunneling and OSI Model Data Security means protecting a database from destructive forces and the unwanted actions of unauthorized users. (Summer, 2004) With the explosion of the World Wide Web and the need to connect various secure private networks to it, it is vital to protect private data from exploitation when it reaches the public networks for transmission. At the heart of the networks through which the information flows is the Open Systems Interconnection (OSI) model. Various techniques are used with respect to the OSI model that helps the data to be transmitted more securely during network transmissions. One of these techniques is Cryptographic tunneling. Cryptographic tunneling operates at the transport layer and network layer of the OSI model. Cryptographic tunneling is primarily used in VPNs or the Virtual Private Networks to add additional security to the data that is flowing through these networks. A VPN is a service that offers secure, reliable connectivity over a shared public network infrastructure such as the Internet. (Mason, 2002) The sender’s authentication, confidentiality of data and hiding the contents of the message is made possible using cryptographic tunneling. When we need data from private businesses to be transmitted through public networks, we make use of tunneling where the public network routing nodes are unaware of the transmission being part of private network. Hiding the packets to make them seem as if they were just like...
