Steganography- a Data Hiding Technique
International Journal of Computer Applications (0975 – 8887) Volume 9– No.7, November 2010 Steganography- A Data Hiding Technique Arvind Kumar Km. Pooja Assistant Professor Vankateshwara institute of computer Vidya College of engineering, Meerut, India Science and technology, Meerut, India ABSTRACT In steganography, the possible cover carriers are innocent looking Steganography is the art of hiding information and an effort to carriers (images, audio, video, text, or some other digitally conceal the existence of the embedded information. It serves as a representative code) which will hold the hidden information. A better way of securing message than cryptography which only message is the information hidden and may be plaintext, cipher text, conceals the content of the message not the existence of the message. images, or anything that can be embedded into a bit stream. Together Original message is being hidden within a carrier such that the the cover carrier and the embedded message create a stego-carrier. changes so occurred in the carrier are not observable. In this paper we Hiding information may require a stego key which is additional secret will discuss how digital images can be used as a carrier to hide information, such as a password, required for embedding the messages. This paper also analyses the performance of some of the information. For example, when a secret message is hidden within a steganography tools. Steganography is a useful tool that allows covert cover image, the resulting product is a stego-image. transmission of information over an over the communications A possible formula of the process may be represented as: cover channel. -
Steganography & Steganalysis

To casual observers, the tablet appeared blank. X Pirate legends tell of the practice of tattooing secret information, such as a map, on the head of someone, so that the hair would conceal it. 5 SteganographySteganography X Both Axis and Allied spies during World War II used such measures as invisible inks -- using milk, fruit juice or urine which darken when heated. X Invisible Ink is also a form of steganography 6 SteganographySteganography X The U.S. government is concerned about the use of Steganography. X Common uses in include the disguising of corporate espionage. X It’s possible that terrorist cells may use it to secretly communicate information X It’s also a very good Anti-forensics mechanism to mitigate the effectiveness of a forensics investigation 7 SteganographySteganography Terror groups hide behind Web encryption By Jack Kelley, USA TODAY AP WASHINGTON — Hidden in the X-rated pictures on several pornographic Web sites and the posted comments on sports chat rooms may lie the encrypted blueprints of the next terrorist attack against the United States or its allies. -

Schmidt St. Cloud State University [email protected] ABSTRACT Steganography has long been regarded as a tool used for illicit and destructive purposes such as crime and warfare. Currently, digital tools are widely available to ordinary computer users also. Steganography software allows both illicit and legitimate users to hide messages so that they will not be detected in transit. -

Statistical Pattern Recognition for Audio Forensics -- Empirical
Statistical Pattern Recognition for Audio Forensics { Empirical Investigations on the Application Scenarios Audio Steganalysis and Microphone Forensics Dissertation zur Erlangung des akademischen Grades Doktoringenieur (Dr.-Ing.) angenommen durch die Fakult¨atf¨urInformatik der Otto-von-Guericke-Universit¨atMagdeburg von: Dipl.-Inform. Christian Kr¨atzer geboren am 12. Dezember 1978 in Halberstadt Gutachter: Prof. Dr. Jana Dittmann, Otto-von-Guericke Universit¨atMagdeburg, Magdeburg, Germany Prof. Dr. Stefan Katzenbeisser, Technische Universit¨atDarmstadt, Darmstadt, Germany Prof. Dr. Scott A. Craver, Binghamton University, Binghamton, NY, United States of America Magdeburg, Germany 23. Mai 2013 Abstract Media forensics is a quickly growing research field struggling to gain the same acceptance as traditional forensic investigation methods. Media forensics tasks such as proving image manipulations on digital images or audio manipulations on digital sound files are as relevant today as they were for their analogue counterparts some decades ago. The difference is that tools like Photoshop now allow a large number of people to manipulate digital media objects with a processing speed far beyond anything imaginable in times when image, audio or video manipulation of analogue media was a hardware- and labour-intensive task requiring skill and experience. Currently, there exists a large number of research prototypes but only a small number of accepted tools that are capable of answering specific questions regularly arising in court cases, such as the origin (source authenticity) of an image or recording, or the integrity of a media file. The reason for this discrepancy between the number of research prototypes and the number of solutions accepted in court has to be sought in the very nature of most judicial systems: Judges have to distinguish between valid bases for evidence and expert testimonies on the one hand, and `junk science' on the other hand. -
