Discover why privacy is a counterproductive, if not obsolete, concept in this startling new book It's only a matter of time-- the modern notion of privacy is quickly evaporating because of technological advancement and social engagement. Whether we like it or not, all our actions and communications are going to be revealed for everyone to see. Exposed: How Revealing Your Data and Eliminating Privacy Increases Trust and Liberates Humanity takes a controversial and insightful look at the concept of privacy and persuasively argues that preparing for a post-private future is better than exacerbating the painful transition by attempting to delay the inevitable. Security expert and author Ben Malisow systematically dismantles common notions of privacy and explains how: Most arguments in favor of increased privacy are wrong Privacy in our personal lives leaves us more susceptible to being bullied or blackmailed Governmental and military privacy leads to an imbalance of power between citizen and state Military supremacy based on privacy is an obsolete concept Perfect for anyone interested in the currently raging debates about governmental, institutional, corporate, and personal privacy, and the proper balance between the public and the private, Exposed also belongs on the shelves of security practitioners and policymakers everywhere.

The recent rapid proliferation in hardware, software, and communication technologies has facilitated the spread of interconnected sensors, actuators, and heterogeneous devices to collect data for offering a new class of advanced services characterized by being available anywhere, at any time and for anyone. This ecosystem is referred to as the Internet of Things (IoT). IoT networks collect, store, and exchange a large amount of heterogeneous data. It has already shown promising outcomes in the provisioning of potentially critical services (e.g., safety applications, healthcare, manufacturing), but it raises many challenges related to the security, data analysis, and limited resources of the performed operations and provided services. Accordingly, research on the data analysis and security of IoT is attractive to both industry and academia. Thus, the central theme of this book is to report novel methodologies, theories, technologies, techniques, and solutions for security and data analytics techniques and energy-aware solutions for IoT. This book aims at addressing these topics across multiple abstraction levels, ranging from architectural models, the provisioning of services, protocols, and interfaces to specific implementation approaches. Furthermore, additional focus will be given to areas related to the role of artificial intelligence in modeling and deploying secure and trustworthy sensors, actuators, and wireless networks for IoT systems. It aims to present the most start-of-the-art technologies to overcome the challenges related to security, data analytics, and energy-aware solutions in the Internet of Things.

Blogwars - The New Political Battleground (Hardcover): David Perlmutter Blogwars - The New Political Battleground (Hardcover)
David Perlmutter
R1,319 Discovery Miles 13 190 Ships in 10 - 15 working days

Political blogs have grown astronomically in the last half-decade. In just one month in 2005, for example, popular blog DailyKos received more unique visitors than the population of Iowa and New Hampshire combined. But how much political impact do bloggers really have? In Blogwars, David D. Perlmutter examines this rapidly burgeoning phenomenon, exploring the degree to which blogs influence--or fail to influence--American political life. Challenging the hype, Perlmutter points out that blogs are not that powerful by traditional political measures: while bloggers can offer cogent and convincing arguments and bring before their readers information not readily available elsewhere, they have no financial, moral, social, or cultural leverage to compel readers to engage in any particular political behavior. Indeed, blogs have scored mixed results in their past political crusades. But in the end, Perlmutter argues that blogs, in their wide dissemination of information and opinions, actually serve to improve democracy and enrich political culture. He highlights a number of the particularly noteworthy blogs from the specialty to the superblog-including popular sites such as Daily Kos, The Huffington Post, Powerlineblog, Instapundit, and Talking Points Memo--and shows how blogs are becoming part of the tool kit of political professionals, from presidential candidates to advertising consultants. While the political future may be uncertain, it will not be unblogged. For many Internet users, blogs are the news and editorial sites of record, replacing traditional newspapers, magazines, and television news programs. Blogwars offers the first full examination of this new and controversial force on America's political landscape.

R2,089 Discovery Miles 20 890 Ships in 18 - 22 working days

Enterprises have made amazing advances by taking advantage of data about their business to provide predictions and understanding of their customers, markets, and products. But as the world of business becomes more interconnected and global, enterprise data is no long a monolith; it is just a part of a vast web of data. Managing data on a world-wide scale is a key capability for any business today. The Semantic Web treats data as a distributed resource on the scale of the World Wide Web, and incorporates features to address the challenges of massive data distribution as part of its basic design. The aim of the first two editions was to motivate the Semantic Web technology stack from end-to-end; to describe not only what the Semantic Web standards are and how they work, but also what their goals are and why they were designed as they are. It tells a coherent story from beginning to end of how the standards work to manage a world-wide distributed web of knowledge in a meaningful way. The third edition builds on this foundation to bring Semantic Web practice to enterprise. Fabien Gandon joins Dean Allemang and Jim Hendler, bringing with him years of experience in global linked data, to open up the story to a modern view of global linked data. While the overall story is the same, the examples have been brought up to date and applied in a modern setting, where enterprise and global data come together as a living, linked network of data. Also included with the third edition, all of the data sets and queries are available online for study and experimentation at data.world/swwo.

Internet of Things Based on Smart Objects - Technology, Middleware and Applications (Hardcover, 2014 ed.): Giancarlo Fortino,... Internet of Things Based on Smart Objects - Technology, Middleware and Applications (Hardcover, 2014 ed.)
Giancarlo Fortino, Paolo Trunfio
R2,658 Discovery Miles 26 580 Ships in 18 - 22 working days

The Internet of Things (IoT) usually refers to a world-wide network of interconnected heterogeneous objects (sensors, actuators, smart devices, smart objects, RFID, embedded computers, etc) uniquely addressable, based on standard communication protocols. Beyond such a definition, it is emerging a new definition of IoT seen as a loosely coupled, decentralized system of cooperating smart objects (SOs). A SO is an autonomous, physical digital object augmented with sensing/actuating, processing, storing, and networking capabilities. SOs are able to sense/actuate, store, and interpret information created within themselves and around the neighbouring external world where they are situated, act on their own, cooperate with each other, and exchange information with other kinds of electronic devices and human users. However, such SO-oriented IoT raises many in-the-small and in-the-large issues involving SO programming, IoT system architecture/middleware and methods/methodologies for the development of SO-based applications. This Book will specifically focus on exploring recent advances in architectures, algorithms, and applications for an Internet of Things based on Smart Objects. Topics appropriate for this Book include, but are not necessarily limited to: - Methods for SO development - IoT Networking - Middleware for SOs - Data Management for SOs - Service-oriented SOs - Agent-oriented SOs - Applications of SOs in Smart Environments: Smart Cities, Smart Health, Smart Buildings, etc. Advanced IoT Projects.

Software Evolution with UML and XML (Hardcover, New): Hongji Yang Software Evolution with UML and XML (Hardcover, New)
Hongji Yang
R2,281 Discovery Miles 22 810 Ships in 18 - 22 working days

Software Evolution with UML and XML provides a forum where expert insights are presented on the subject of linking three current phenomena: software evolution, UML and XML. Software evolution and reengineering are a real problem in the software industry; various attempts have been made in these areas and there is still room for improvement. Tackling evolution with the help of UML and XML can be very beneficial to the software community, especially as the cost of software evolution makes up a considerable proportion, sometimes even 70-80 per cent, of the total budget of a software system. Software Evolution with UML and XML not only investigates the potential powerful applications of two popularly used languages, UML and XML, in the field of software evolution, but also discovers what will happen when these three are linked to work together.

Physical-Layer Security for Cooperative Relay Networks (Hardcover, 1st ed. 2016): Yulong Zou, Jia Zhu Physical-Layer Security for Cooperative Relay Networks (Hardcover, 1st ed. 2016)
Yulong Zou, Jia Zhu
R2,653 Discovery Miles 26 530 Ships in 18 - 22 working days

This book presents physical-layer security as a promising paradigm for achieving the information-theoretic secrecy required for wireless networks. It explains how wireless networks are extremely vulnerable to eavesdropping attacks and discusses a range of security techniques including information-theoretic security, artificial noise aided security, security-oriented beamforming, and diversity assisted security approaches. It also provides an overview of the cooperative relaying methods for wireless networks such as orthogonal relaying, non-orthogonal relaying, and relay selection.Chapters explore the relay-selection designs for improving wireless secrecy against eavesdropping in time-varying fading environments and a joint relay and jammer selection for wireless physical-layer security, where a relay is used to assist the transmission from the source to destination and a friendly jammer is employed to transmit an artificial noise for confusing the eavesdropper. Additionally, the security-reliability tradeoff (SRT) is mathematically characterized for wireless communications and two main relay-selection schemes, the single-relay and multi-relay selection, are devised for the wireless SRT improvement. In the single-relay selection, only the single best relay is chosen for assisting the wireless transmission, while the multi-relay selection invokes multiple relays for simultaneously forwarding the source transmission to the destination.Physical-Layer Security for Cooperative Relay Networks is designed for researchers and professionals working with networking or wireless security. Advanced-level students interested in networks, wireless, or privacy will also find this book a useful resource.
