Download or read book User Centred and Context Aware Identity Management in Mobile Ad Hoc Networks written by Abdullahi Arabo and published by Cambridge Scholars Publishing. This book was released on 2013-12-12 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergent notion of ubiquitous computing makes it possible for mobile devices to communicate and provide services via networks connected in an ad-hoc manner. These have resulted in the proliferation of wireless technologies such as Mobile Ad-hoc Networks (MANets), which offer attractive solutions for services that need flexible setup as well as dynamic and low cost wireless connectivity. However, the growing trend outlined above also raises serious concerns over Identity Management (IM) due to a dramatic increase in identity theft. The problem is even greater in service-oriented architectures, where partial identities are sprinkled across many services and users have no control over such identities. This book provides a review of some issues of contextual computing, its implications and usage within pervasive environments. The book will also introduce the concept of Security of Systems-of-Systems (SoS) Composition and its security implications within the domain of ubiquitous computing and Crisis Management in large scale disaster recovery situations and scenarios. To tackle the above problems, the book will emphasise the fact that it is essential to allow users to have full control over their own identities in MANet environments. So far, the development of such identity control remains a significant challenge for the research community. The main focus of this book is on the area of identity management in MANets and emergency situations by using context-awareness and user-centricity together with its security issues and implications. Context-awareness allows us to make use of partial identities as a way of user identity protection and node identification. User-centricity is aimed at putting users in control of their partial identities, policies and rules for privacy protection. These principles help us to propose an innovative, easy-to-use identity management framework for MANets. The framework makes the flow of partial identities explicit; gives users control over such identities based on their respective situations and contexts, and creates a balance between convenience and privacy. The book presents our proposed framework, its development and lab results/evaluations, and outlines possible future work to improve the framework. This book will be of great interest and benefit to undergraduate students undertaking computer science modules on security and ubiquitous computing and postgraduate students studying the security of large scale systems of systems composition, as well as those doing their projects in those areas. The book will also accommodate the needs of early researchers and DPhil/PhD or MPhil students exploring the concept of security in ubiquitous environments, while additionally being of great interest to lecturers teaching related modules and industrial researchers.

Book excerpt: Contextual information and Identity Management (IM) is of paramount importance in the growing use of portable mobile devices for sharing information and communication between emergency services in pervasive ad-hoc environments. Mobile Ad-hoc Networks (MANets) play a vital role within such a context. The concept of ubiquitous/pervasive computing is intrinsically tied to wireless communications. Apart from many remote services, proximity services (context-awareness) are also widely available, and people rely on numerous identities to access these services. The inconvenience of these identities creates significant security vulnerability as well as user discomfort, especially from the network and device point of view in MANet environments. The need of displaying only relevant contextual information (CI) with explicit user control arises in energy constraint devices and in dynamic situations. We propose an approach that allows users to define policies dynamically and a ContextRank Algorithm which will detect the usability of CI. The proposed approach is not only efficient in computation but also gives users total control and makes policy specification more expressive. In this Chapter, the authors address the issue of dynamic policy specification, usage of contextual information to facilitate IM and present a User-centered and Context-aware Identity Management (UCIM) framework for MANets.

Download or read book Languages Compilers and Run time Environments for Distributed Memory Machines written by J. Saltz and published by Elsevier. This book was released on 2014-06-28 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Papers presented within this volume cover a wide range of topics related to programming distributed memory machines. Distributed memory architectures, although having the potential to supply the very high levels of performance required to support future computing needs, present awkward programming problems. The major issue is to design methods which enable compilers to generate efficient distributed memory programs from relatively machine independent program specifications. This book is the compilation of papers describing a wide range of research efforts aimed at easing the task of programming distributed memory machines.

Download or read book Entity Oriented Search written by Krisztian Balog and published by Springer. This book was released on 2018-10-02 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book covers all facets of entity-oriented search—where “search” can be interpreted in the broadest sense of information access—from a unified point of view, and provides a coherent and comprehensive overview of the state of the art. It represents the first synthesis of research in this broad and rapidly developing area. Selected topics are discussed in-depth, the goal being to establish fundamental techniques and methods as a basis for future research and development. Additional topics are treated at a survey level only, containing numerous pointers to the relevant literature. A roadmap for future research, based on open issues and challenges identified along the way, rounds out the book. The book is divided into three main parts, sandwiched between introductory and concluding chapters. The first two chapters introduce readers to the basic concepts, provide an overview of entity-oriented search tasks, and present the various types and sources of data that will be used throughout the book. Part I deals with the core task of entity ranking: given a textual query, possibly enriched with additional elements or structural hints, return a ranked list of entities. This core task is examined in a number of different variants, using both structured and unstructured data collections, and numerous query formulations. In turn, Part II is devoted to the role of entities in bridging unstructured and structured data. Part III explores how entities can enable search engines to understand the concepts, meaning, and intent behind the query that the user enters into the search box, and how they can provide rich and focused responses (as opposed to merely a list of documents)—a process known as semantic search. The final chapter concludes the book by discussing the limitations of current approaches, and suggesting directions for future research. Researchers and graduate students are the primary target audience of this book. A general background in information retrieval is sufficient to follow the material, including an understanding of basic probability and statistics concepts as well as a basic knowledge of machine learning concepts and supervised learning algorithms.

Download or read book Ireland written by International Monetary Fund. European Dept. and published by International Monetary Fund. This book was released on 2016-07-28 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2016 Article IV Consultation highlights that the rebound of the Irish economy has been exceptional. High frequency indicators suggest that growth momentum has continued in 2016. Solid job creation has reduced the unemployment rate below 8 percent. Inflation has hovered around zero as low commodity and food prices more than offset rising cost of services, particularly housing rents. Taking into account negative spillovers, real GDP growth is projected to decline to just below 5 percent in 2016 and converge to its estimated potential over the medium-term on the back of more moderate export growth and investment activity.
