A graphic user interface for rapid integration of Steganography software
1996Co-Authors: David Raiman WoottenAbstract:Abstract : Steganography is a method an individual uses to secretly communicate, whereby the transmitting agent hides a message within some medium, so that only an intended recipient can detect the message's presence. Researchers who apply this methodology to digital imagery currently have no X Windows-based graphic user interface software package through which they may aggregate, test, and demonstrate their Steganography Programs. Such a package would contain features to encode data to and extract data from digital imagery, convert the files to other graphic file formats, display imagery, and offer some utility to analyze change between unencoded original images and their encoded equivalent. The Steganography software development package presented in this thesis, named Steganography Toolbox, satisfies these requirements. It provides the above described features, plus the ability to delete unneeded files, all in an X Windows graphic user interface. It permits the user, who writes a separately executable Steganography Program, to attach it to the graphic interface with little additional Programming effort. The thesis describes a method to create a menu-selected dialog box containing the necessary widgets, which invokes the desired Program through a system() call. The thesis includes Steganography Toolbox's structured design documentation, from system requirements to process specifications. The thesis also describes how requirements-based software tests were performed on each module to verify proper function and error-handling.

header for SPIE use Principle and applications of BPCS-Steganography
2016Co-Authors: Eiji Kawaguchi, Richard O. EasonAbstract:Steganography is a technique to hide secret information in some other data (we call it a vessel) without leaving any apparent evidence of data alteration. All of the traditional steganographic techniques have limited information-hiding capacity. They can hide only 10 % (or less) of the data amounts of the vessel. This is because the principle of those techniques was either to replace a special part of the frequency components of the vessel image, or to replace all the least significant bits of a multi-valued image with the secret information. Our new Steganography uses an image as the vessel data, and we embed secret information in the bit-planes of the vessel. This technique makes use of the characteristics of the human vision system whereby a human cannot perceive any shape information in a very complicated binary pattern. We can replace all of the “noise-like ” regions in the bit-planes of the vessel image with secret data without deteriorating the image quality. We termed our Steganography “BPCS-Steganography, ” which stands for Bit-Plane Complexity Segmentation Steganography. We made an experimental system to investigate this technique in depth. The merits of BPCS-Steganography found by the experiments are as follows. 1. The information hiding capacity of a true color image is around 50%. 2. A sharpening operation on the dummy image increases the embedding capacity quite a bit. 3. Canonical Gray coded bit planes are more suitable for BPCS-Steganography than the standard binary bit planes. 4. Randomization of the secret data by a compression operation makes the embedded data more intangible. 5. Customization of a BPCS-Steganography Program for each user is easy. It further protects against eavesdropping on the embedded information

Video Steganography using Flash Video (FLV)
2009 IEEE Instrumentation and Measurement Technology Conference, 2009Co-Authors: A.j. Mozo, M.e. Obien, C.j. Rigor, D.f. Rayel, K. Chua, G. TangonanAbstract:This paper aims to describe our research and software implementation in the field of video Steganography. Because of security threats today through modern malevolent technology, confidential information is at risk such as medical records and banking or financial data. The group provided a solution by protecting this sensitive information inside videos. The project focused on using Flash Videos (.flv file extension) because of its simple file structure, its relatively small size compared to other video file formats, and its popularity in video-hosting websites. Intensive experimentation on how the FLV file structure can be manipulated to hold additional data were done. Through these experiments, the characteristics of the FLV provided the group to implement a C++ Program that features embedding any type of data in the FLV, extracting that same hidden information, as well as compressing the FLV to compensate for the increase in file size. Very promising results include 100% lossless extraction, perfect original picture and sound quality for the uncompressed FLV embedded with data and uncompromised integrity of hidden data when modified FLVs are transferred through the Internet through e-mail or video-hosting websites. An application dealing with the medical records' privacy is currently ongoing. Lastly, a recent article saying that doing Steganography on a file that has been already “steganized” (“double-stegging”) could damage the file and jeopardize the extraction of the hidden file for the sake of making espionage work against itself. This statement have been supported and confirmed possible by the group as successive embedding using the Video Steganography Program makes the original message “inextractable” using the same Program.

Comparison of Video Steganography Methods for Watermark Embedding
Applied Computer Systems, 2016Co-Authors: David Griberman, Pavel RusakovAbstract:Abstract The paper focuses on the comparison of video Steganography methods for the purpose of digital watermarking in the context of copyright protection. Four embedding methods that use Discrete Cosine and Discrete Wavelet Transforms have been researched and compared based on their embedding efficiency and fidelity. A video Steganography Program has been developed in the Java Programming language with all of the researched methods implemented for experiments. The experiments used 3 video containers with different amounts of movement. The impact of the movement has been addressed in the paper as well as the ways of potential improvement of embedding efficiency using adaptive embedding based on the movement amount. Results of the research have been verified using a survey with 17 participants.
