This groundbreaking text examines the problem of user authentication from a completely new viewpoint. Rather than describing the requirements, technologies and implementation issues of designing point-of-entry authentication, the book introduces and investigates the technological requirements of implementing transparent user authentication - where authentication credentials are captured during a user's normal interaction with a system. This approach would transform user authentication from a binary point-of-entry decision to a continuous identity confidence measure. Topics and features: discusses the need for user authentication; reviews existing authentication approaches; introduces novel behavioural biometrics techniques; examines the wider system-specific issues with designing large-scale multimodal authentication systems; concludes with a look to the future of user authentication.

The book shows how researchers, practitioners, and designers can improve user experiences with technology by understanding various user learning styles and characteristics when they interact with new and challenging applications and interfaces. Quality of experience in this new technological environment is affected by the learning curve involved in being able to use the new interfaces in a satisfactory way. The author explores the variations in quality of experience when considering learning and ethics when interacting with new, emerging technologies. The author shows how results can be applied to technologies such as big data, AI, 5G, and Internet of Things (IoT). Taken into account are also safety and security requirements, context, environment, etc. The book explores the idea of learning, ethics, and the idea that there exists a "recipe" for a satisfactory interaction with technology if such relevant parameters are taken into consideration. Analyzes user habits to improve quality of experience when interacting with technology; Shows how to apply quality of service techniques to 5G, IoT, big data and AI; Uses behavior models to analyze interactions to improve the user quality of experience.

This edited book focuses on speech etiquette, examining the rules that govern communication in various online communities: professional, female, and ethnospecific. The contributors analyze online communication in the Slavic languages Russian, Slovak, Polish, and Belarusian, showing how the concept of speech etiquette differs from the concept of politeness, although both reflect the relationship between people in interaction. Online communities are united on the basis of common informative or phatic illocutions among their participants, and their speech etiquette is manifested in stable forms of conducting discussions - stimulating and responding. Each group has its own ideas of unacceptable speech behavior and approaches to sanitation, and the rules of speech etiquette in each group determine the degree of rapport and distancing between the participants in discourse. The chapters in this book explore how rapport and distance are established through acts such as showing attention to the addressee and increasing his or her communicative status; reducing or increasing the illocutionary power of evaluations and motivations; and evaluating one's own or someone else's speech. The volume will be of interest to researchers studying online communication in such diverse fields as linguistics, sociology, anthropology, programming, and media studies.

This book makes the case that traditional security design does not take the end-user into consideration, and therefore, fails. This book goes on to explain, using a series of examples, how to rethink security solutions to take users into consideration. By understanding the limitations and habits of users - including malicious users, aiming to corrupt the system - this book Illustrates how better security technologies are made possible. Traditional security books focus on one of the following areas: cryptography, security protocols, or existing standards. They rarely consider the end user as part of the security equation, and when they do, it is in passing. This book considers the end user as the most important design consideration, and then shows how to build security and privacy technologies that are both secure and which offer privacy. This reduces the risk for social engineering and, in general, abuse. Advanced-level students interested in software engineering, security and HCI (Human Computer Interaction) will find this book useful as a study guide. Engineers and security practitioners concerned with abuse and fraud will also benefit from the methodologies and techniques in this book.

This book brings together the insights from three different areas, Information Seeking and Retrieval, Cognitive Psychology, and Behavioral Economics, and shows how this new interdisciplinary approach can advance our knowledge about users interacting with diverse search systems, especially their seemingly irrational decisions and anomalies that could not be predicted by most normative models. The first part "Foundation" of this book introduces the general notions and fundamentals of this new approach, as well as the main concepts, terminology and theories. The second part "Beyond Rational Agents" describes the systematic biases and cognitive limits confirmed by behavioral experiments of varying types and explains in detail how they contradict the assumptions and predictions of formal models in information retrieval (IR). The third part "Toward A Behavioral Economics Approach" first synthesizes the findings from existing preliminary research on bounded rationality and behavioral economics modeling in information seeking, retrieval, and recommender system communities. Then, it discusses the implications, open questions and methodological challenges of applying the behavioral economics framework to different sub-areas of IR research and practices, such as modeling users and search sessions, developing unbiased learning to rank and adaptive recommendations algorithms, implementing bias-aware intelligent task support, as well as extending the conceptualization and evaluation on IR fairness, accountability, transparency and ethics (FATE) with the knowledge regarding both human biases and algorithmic biases. This book introduces a behavioral economics framework to IR scientists seeking a new perspective on both fundamental and new emerging problems of IR as well as the development and evaluation of bias-aware intelligent information systems. It is especially intended for researchers working on IR and human-information interaction who want to learn about the potential offered by behavioral economics in their own research areas.

Interaction design is acknowledged as an important area of study, and more especially of design practice. Hugely popular and profitable consumer devices, such as mobile phones and tablets, are seen as owing much of their success to the way they have been designed, not least their interface characteristics and the styles of interaction that they support. Interaction design studies point to the importance of a user-centred approach, whereby products are in principle designed around their future users' needs and capacities. However, it is the market, and marketing, that determine which products are available for people to interact with and to a great extent what their designed characteristics are. Primitive Interaction Design is based on the realisation that designers need to be freed from the marketplace and industry pressure, and that the usual user-centred arguments are not enough to make a practical difference. Interaction designers are invited to cast themselves as "savages", as if wielding primitive tools in concrete physical environments. A theoretical perspective is presented that opens up new possibilities for designers to explore fresh ideas and practices, including the importance of conscious and unconscious being, emptiness and trickery. Building on this, a set of design tools for primitive design work is presented and illustrated with practical examples. This book will be of particular interest to undergraduate and graduate students and researchers in interaction design and HCI, as well as practicing interaction designers and computer professions. It will also appeal to those with an interest in psychology, anthropology, cultural studies, design and the future of technology in society.

"Personality Capture and Emulation" is the gateway to an amazing future that actually may be achieved, enabling the preservation and simulation of human personalities at progressively higher levels of fidelity. This challenge is no longer the province merely of uninhibited visionaries, but has become a solid field of research, drawing upon a wide range of information technologies in human-centered computing and cyber-human systems. Even at modest levels of accomplishment, research in this emerging area requires convergence of cognitive, social, and cultural sciences, in cooperation with information engineering and artificial intelligence, thus stimulating new multidisciplinary perspectives. Therefore this book will inspire many specific research and development projects that will produce their own valuable outcomes, even as the totality of the work moves us closer to a major revolution in human life. Will it ever really be possible to transfer a human personality at death to a technology that permits continued life?Or will people come to see themselves as elements in a larger socio-cultural system, for which a societal information system can provide collective immortality even after the demise of individuals? A large number and variety of pilot studies and programming projects are offered as prototypes for research that innovators in many fields may exploit for the achievement of their own goals. Together, they provide an empirical basis to strengthen the intellectual quality of several current debates at the frontiers of the human and information sciences."
