The Science of Quantitative Information Flow

Author: Mário S. Alvim
Publisher: Springer Nature
ISBN: 3319961314
Category : Computers
Languages : en
Pages : 478

Book Description
This book presents a comprehensive mathematical theory that explains precisely what information flow is, how it can be assessed quantitatively – so bringing precise meaning to the intuition that certain information leaks are small enough to be tolerated – and how systems can be constructed that achieve rigorous, quantitative information-flow guarantees in those terms. It addresses the fundamental challenge that functional and practical requirements frequently conflict with the goal of preserving confidentiality, making perfect security unattainable. Topics include: a systematic presentation of how unwanted information flow, i.e., "leaks", can be quantified in operationally significant ways and then bounded, both with respect to estimated benefit for an attacking adversary and by comparisons between alternative implementations; a detailed study of capacity, refinement, and Dalenius leakage, supporting robust leakage assessments; a unification of information-theoretic channels and information-leaking sequential programs within the same framework; and a collection of case studies, showing how the theory can be applied to interesting realistic scenarios. The text is unified, self-contained and comprehensive, accessible to students and researchers with some knowledge of discrete probability and undergraduate mathematics, and contains exercises to facilitate its use as a course textbook.

Information Flow

Author: Jon Barwise
Publisher: Cambridge University Press
ISBN: 1316582663
Category : Computers
Languages : en
Pages : 292

Book Description
Information is a central topic in computer science, cognitive science and philosophy. In spite of its importance in the 'information age', there is no consensus on what information is, what makes it possible, and what it means for one medium to carry information about another. Drawing on ideas from mathematics, computer science and philosophy, this book addresses the definition and place of information in society. The authors, observing that information flow is possible only within a connected distribution system, provide a mathematically rigorous, philosophically sound foundation for a science of information. They illustrate their theory by applying it to a wide range of phenomena, from file transfer to DNA, from quantum mechanics to speech act theory.

An Introduction to Transfer Entropy

Author: Terry Bossomaier
Publisher: Springer
ISBN: 3319432222
Category : Computers
Languages : en
Pages : 210

Book Description
This book considers a relatively new metric in complex systems, transfer entropy, derived from a series of measurements, usually a time series. After a qualitative introduction and a chapter that explains the key ideas from statistics required to understand the text, the authors then present information theory and transfer entropy in depth. A key feature of the approach is the authors' work to show the relationship between information flow and complexity. The later chapters demonstrate information transfer in canonical systems, and applications, for example in neuroscience and in finance. The book will be of value to advanced undergraduate and graduate students and researchers in the areas of computer science, neuroscience, physics, and engineering.

Knowledge and the Flow of Information

Author: Fred I. Dretske
Publisher: Mit Press
ISBN: 9780262540384
Category : Computers
Languages : en
Pages : 288

Book Description
What distinguishes clever computers from stupid people (besides their components)? The author of Seeing and Knowing presents in his new book a beautifully and persuasively written interdisciplinary approach to traditional problems--a clearsighted interpretation of information theory.Psychologists, biologists, computer scientists, and those seeking a general unified picture of perceptual-cognitive activity will find this provocative reading.The problems Dretske addresses in Knowledge and the Flow of Information--What is knowledge? How are the sensory and cognitive processes related? What makes mental activities mental?--appeal to a wide audience. The conceptual tools used to deal with these questions (information, noise, analog versus digital coding, etc.) are designed to make contact with, and exploit the findings of, empirical work in the cognitive sciences. A concept of information is developed, one deriving from (but not identical with) the Shannon idea familiar to communication theorists, in terms of which the analyses of knowledge, perception, learning, and meaning are expressed.The book is materialistic in spirit--that is, spiritedly materialistic--devoted to the view that mental states and processes are merely special ways physical systems have of processing, coding, and using information.

The Phenomenon of Information

Author: Mario Pérez-Montoro
Publisher: Scarecrow Press
ISBN: 1461673380
Category : Education
Languages : en
Pages : 299

Book Description
We are surrounded by information. Even the most routine situations in which we find ourselves conceal a hidden information flow. Every step we take, a host of signals meet us, providing information about what is happening in other parts of reality. The cherry tree in bloom reveals that spring has arrived. The footprint left on wet sand indicates that someone has walked along the beach. A red traffic light signals that we must bring our car to a halt. In The Phenomenon of Information, author Mario Pérez-Montoro addresses the problems of providing a theoretical explanation of how a signal carries informational content, how to identify its characteristics, and how to define the mechanisms for describing it. To do this, Pérez-Montoro examines several theoretical approaches to the phenomenon of information: the mathematical theory of communication, Dretske's approach, and the relational theory of meaning. A critique of these efforts leads to the author's definition of informational content, named "the extensional approach," which is designed to overcome the conceptual limitations of the previous theories. The author proposes that his definition might serve as a basis on which a satisfactory analysis of the concept of information can be developed.

Integration of Information Flow for Greening Supply Chain Management

Author: Adam Kolinski
Publisher: Springer
ISBN: 9783030243579
Category : Science
Languages : en
Pages : 415

Book Description
This book provides a framework for integrating information management in supply chains. Current trends in business practice have made it necessary to explore the potential held by information integration with regard to environmental aspects. Information flow integration provides an opportunity to focus on the creation of a more “green” supply chain. However, it is currently difficult to identify the impact of information integration on greening a supply chain in a wide range of practical applications. Accordingly, this book focuses on the potential value of information integration solutions in terms of greening supply chain management. It covers the following major topics: Application of information flow standards in the supply chain Information systems and technological solutions for integrating information flows in supply chains The Internet of Things and the industry 4.0 concept, with regard to the integration of supply chains Modeling and simulation of logistics processes Decision-making tools enabling the greening of supply chains

Pages : 192

Book Description
Portfolio Optimization with Different Information Flow recalls the stochastic tools and results concerning the stochastic optimization theory and the enlargement filtration theory.The authors apply the theory of the enlargement of filtrations and solve the optimization problem. Two main types of enlargement of filtration are discussed: initial and progressive, using tools from various fields, such as from stochastic calculus and convex analysis, optimal stochastic control and backward stochastic differential equations. This theoretical and numerical analysis is applied in different market settings to provide a good basis for the understanding of portfolio optimization with different information flow. - Presents recent progress of stochastic portfolio optimization with exotic filtrations - Shows you how to apply the tools of the enlargement of filtrations to resolve the optimization problem - Uses tools from various fields from enlargement of filtration theory, stochastic calculus, convex analysis, optimal stochastic control, and backward stochastic differential equations
