TL;DR: This survey paper is focused on the development and current status of steganographic techniques for grayscale images, and shall separately introduce schemes with high hiding capacities and scheme with high imperceptibility.
Abstract: Image steganography is a covert communication method that uses an image as the cover to hide the truth from potential attackers that some secret message hidden in the image is being transported. When we appreciate the astonishing beauty of a world famous picture in its digital form on the computer, it is hard to imagine that the picture might actually be working as a messenger, carrying some invisible important secret message along with it. In other words, steganography is a collection of cryptographic techniques that provide protection to the secret message by offering it the appearance of an image. In this survey paper, our focus is on the development and current status of steganographic techniques for grayscale images. We shall separately introduce schemes with high hiding capacities and schemes with high imperceptibility. The advantages and disadvantages of those schemes will be closely analyzed, offering directions for our future research efforts.

TL;DR: The LSB embedding technique is explained, the evaluation results for 2,4,6 Least significant bits for a .pngfile and a .bmp file are presented and a strong focus on the LSB techniques in image Steganography is provided.
Abstract: Steganography is the art of hiding information in information is gaining momentum as it scores over cryptography because it enables to embedd the secret message to cover images. Steganographic techniques offer more promise in digital image processing. The Least Significant Bit embedding technique suggests that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden image in the cover file. This technique can be used for hiding images in 24-bit, 8-bit or gray scale format. We emphasize strongly on image Steganography providing a strong focus on the LSB techniques in image Steganography. This paper explains the LSB embedding technique and presents the evaluation results for 2,4,6 Least significant bits for a .png file and a .bmp file.

TL;DR: This paper addresses the directional cover set problem (DCS) of finding a cover set in a directional sensor network, in which the directions cover all the targets, and proposes both centralized and distributed algorithms for the DCS.
Abstract: A directional sensor network consists of a number of directional sensors, which can switch to several directions to extend their sensing ability to cover the interested targets in a given area. Because a directional sensor has a smaller angle of sensing range or even does not cover any target when it is deployed, how to cover the interested targets becomes a major problem in directional sensor networks. In this paper, we address the directional cover set problem (DCS) of finding a cover set in a directional sensor network, in which the directions cover all the targets. We propose both centralized and distributed algorithms for the DCS. We also introduce two applications that utilize these algorithms to extend the network work time while maximizing the coverage of the targets. Simulation results are presented to demonstrate the performance of these algorithms and the applications.

TL;DR: This work proposes that the mix generate cover traffic that mimics the sending patterns of users in the system, and shows through simulation how this makes it difficult for an attacker to discern cover from real traffic and perform attacks based on statistical analysis.
Abstract: Anonymous communications provides an important privacy service by keeping passive eavesdroppers from linking communicating parties. However, using long-term statistical analysis of traffic sent to and from such a system, it is possible to link senders with their receivers. Cover traffic is an effective, but somewhat limited, counter strategy against this attack. Earlier work in this area proposes that privacy-sensitive users generate and send cover traffic to the system. However, users are not online all the time and cannot be expected to send consistent levels of cover traffic, drastically reducing the impact of cover traffic. We propose that the mix generate cover traffic that mimics the sending patterns of users in the system. This receiver-bound cover helps to make up for users that aren't there, confusing the attacker. We show through simulation how this makes it difficult for an attacker to discern cover from real traffic and perform attacks based on statistical analysis. Our results show that receiver-bound cover substantially increases the time required for these attacks to succeed. When our approach is used in combination with user-generated cover traffic, the attack takes a very long time to succeed.

Abstract: Telecommunications policy profoundly affects the economy and our everyday lives Yet accounts of important telecommunications issues tend to be either superficial (and inaccurate) or mired in jargon and technical esoterica In Digital Crossroads, Jonathan Nuechterlein and Philip Weiser offer a clear, balanced, and accessible analysis of competition policy issues in the telecommunications industry After giving a big picture overview of the field, they present sharply reasoned analyses of the major technological, economic, and legal developments confronting communications policymakers in the twenty-first century Since the passage of the Telecommunications Act of 1996, when Congress fundamentally reoriented the existing regulatory scheme, no book has cogently explained the intricacies of telecommunications competition policy in the Internet age for general readers, students, and practitioners alike Digital Crossroads meets this need, focusing on the regulatory dimensions of competition in wireline and wireless telephone service; competition among rival platforms for broadband Internet service and video distribution; and the Internet's transformation of every aspect of the telecommunications industry, particularly through the emergence of "voice over Internet protocol" (VoIP) The authors explain not just the complicated legal issues governing the industry, but also the rapidly changing technological and economic context in which these issues arise The book includes extensive endnotes and tables that cover relevant court decisions, FCC orders, and academic commentaries; a glossary of acronyms; a statutory addendum containing the most important provisions of federal telecommunications law; and two appendixes with information on more specialized topics

TL;DR: This paper embeds a binary image in both video frames and audio tracks to ensure higher payload and security.
Abstract: This paper is dealing with steganography in DVD content. Classical steganography concerns itself on ways of embedding a secret message in a cover message such as a video stream or audio recording. The embedding is typically parameterized by a key. Without knowledge about this key, it is difficult for a third party to detect or remove the embedded material. Once sicret information was embedded in the cover object, this material is called a stego object [1], [2]. We embed a binary image in both video frames and audio tracks. This modification ensures higher payload and security.
