This book provides an introduction to software-defined radio and cognitive radio, along with methodologies for applying knowledge representation, semantic web, logic reasoning and artificial intelligence to cognitive radio, enabling autonomous adaptation and flexible signaling. Readers from the wireless communications and software-defined radio communities will use this book as a reference to extend software-defined radio to cognitive radio, using the semantic technology described.

This book constitutes the proceedings of the 9th International Symposium on Security and Privacy in Social Networks and Big Data, SocialSec 2023, which took place in Canterbury, UK, in August 2023. The 10 full papers and 4 short papers presented in this volume were carefully reviewed and selected from 29 submissions. They were organized in topical sections as follows: information abuse and political discourse; attacks; social structure and community; and security and privacy matters. Papers "Data Reconstruction Attack Against Principal Component Analysis" and "Edge local Differential Privacy for Dynamic Graphs" are published Open Access under the CC BY 4.0 License.

Cognitive models and software tools have been widely used for both research and commercial purposes. Although they have proved very useful, there are some limitations preventing large-scale modeling and simulation tasks to be carried out efficiently and effectively. In this book, we aim to provide readers with a systematic overview of state-of-the-art cognitive modeling software tools and applications and an introduction to a new software framework for facilitating large-scale modeling and simulation of human-performance tasks. The authors first review cognitive modeling theories and then present an overview of state-of-the-art software tools for cognitive modeling and simulation. Finally, the book focuses on the new software framework and a research prototype called CogTool+, including how to incorporate behavioral data such as eye-tracking data in modeling and simulation tasks. Typical applications of CogTool+ in HCI and cyber security are given to demonstrate its usefulness.

This book constitutes the refereed post-conference proceedings of the Interdisciplinary Workshop on Trust, Identity, Privacy, and Security in the Digital Economy, DETIPS 2020; the First International Workshop on Dependability and Safety of Emerging Cloud and Fog Systems, DeSECSys 2020; Third International Workshop on Multimedia Privacy and Security, MPS 2020; and the Second Workshop on Security, Privacy, Organizations, and Systems Engineering, SPOSE 2020; held in Guildford, UK, in September 2020, in conjunction with the 25th European Symposium on Research in Computer Security, ESORICS 2020. A total of 42 papers was submitted. For the DETIPS Workshop 8 regular papers were selected for presentation. Topics of interest address various aspect of the core areas in relation to digital economy. For the DeSECSys Workshop 4 regular papers are included. The workshop had the objective of fostering collaboration and discussion among cyber-security researchers and practitioners to discuss the various facets and trade-o s of cyber security. In particular, applications, opportunities and possible shortcomings of novel security technologies and their integration in emerging application domains. For the MPS Workshop 4 regular papers are presented which cover topics related to the security and privacy of multimedia systems of Internet-based video conferencing systems (e.g., Zoom, Microsoft Teams, Google Meet), online chatrooms (e.g., Slack), as well as other services to support telework capabilities. For the SPOSE Workshop 3 full papers were accepted for publication. They reflect the discussion, exchange, and development of ideas and questions regarding the design and engineering of technical security and privacy mechanisms with particular reference to organizational contexts.
