This book covers newly developed and novel Steganography techniques and algorithms. The book outlines techniques to provide security to a variety of applications using Steganography, with the goal of both hindering an adversary from decoding a hidden message, and also preventing an adversary from suspecting the existence of covert communications. The book looks into applying these newly designed and improved algorithms to provide a new and efficient Steganographic system, called Characteristic Region-Based Image Steganography (CR-BIS). The algorithms combine both the robustness of the Speeded-Up Robust Features technique (SURF) and Discrete Wavelet Transform (DWT) to achieve characteristic region Steganography synchronization. The book also touches on how to avoid hiding data in the whole image by dynamically selecting characteristic regions for the process of embedding. Applies and discusses innovative techniques for hiding text in a digital image file or even using it as a key to the encryption; Provides a variety of methods to achieve characteristic region Steganography synchronization; Shows how Steganography improves upon cryptography by using obscurity features.

Investigate crimes involving cryptocurrencies and other blockchain technologies Bitcoin has traditionally been the payment system of choice for a criminal trading on the Dark Web, and now many other blockchain cryptocurrencies are entering the mainstream as traders are accepting them from low-end investors putting their money into the market. Worse still, the blockchain can even be used to hide information and covert messaging, unknown to most investigators. Investigating Cryptocurrencies is the first book to help corporate, law enforcement, and other investigators understand the technical concepts and the techniques for investigating crimes utilizing the blockchain and related digital currencies such as Bitcoin and Ethereum. Understand blockchain and transaction technologies Set up and run cryptocurrency accounts Build information about specific addresses Access raw data on blockchain ledgers Identify users of cryptocurrencies Extracting cryptocurrency data from live and imaged computers Following the money With nearly $150 billion in cryptocurrency circulating and $3 billion changing hands daily, crimes committed with or paid for with digital cash are a serious business. Luckily, Investigating Cryptocurrencies Forensics shows you how to detect it and, more importantly, stop it in its tracks.

What constitutes an identity, how do new technologies affect identity, how do we manage identities in a globally networked information society? The increasing div- sity of information and communication technologies and their equally wide range of usage in personal, professional and official capacities raise challenging questions of identity in a variety of contexts. The aim of the IFIP/FIDIS Summer Schools has been to encourage young a- demic and industry entrants to share their own ideas about privacy and identity m- agement and to build up collegial relationships with others. As such, the Summer Schools have been introducing participants to the social implications of information technology through the process of informed discussion. The 4th International Summer School took place in Brno, Czech Republic, during September 1-7, 2008. It was organized by IFIP (International Federation for Infor- tion Processing) working groups 9.2 (Social Accountability), 9.6/11.7 (IT Misuse and the Law) and 11.6 (Identity Management) in cooperation with the EU FP6 Network of Excellence FIDIS and Masaryk University in Brno. The focus of the event was on security and privacy issues in the Internet environment, and aspects of identity m- agement in relation to current and future technologies in a variety of contexts.

Proofs play a central role in advanced mathematics and theoretical computer science, yet many students struggle the first time they take a course in which proofs play a significant role. This bestselling text's third edition helps students transition from solving problems to proving theorems by teaching them the techniques needed to read and write proofs. Featuring over 150 new exercises and a new chapter on number theory, this new edition introduces students to the world of advanced mathematics through the mastery of proofs. The book begins with the basic concepts of logic and set theory to familiarize students with the language of mathematics and how it is interpreted. These concepts are used as the basis for an analysis of techniques that can be used to build up complex proofs step by step, using detailed 'scratch work' sections to expose the machinery of proofs about numbers, sets, relations, and functions. Assuming no background beyond standard high school mathematics, this book will be useful to anyone interested in logic and proofs: computer scientists, philosophers, linguists, and, of course, mathematicians.
