Digital media has exploded over the past quarter century, and in particular the past decade. As varieties of digital media multiply, scholars are beginning to examine its origins, organization, and preservation, which present new challenges compared to traditional media. To examine issues from multiple perspectives, experts were invited to an invitation-only workshop on digital media. The participants were carefully chosen to represent a variety of backgrounds and perspectives, ranging from humanities and fine arts to communication theory. The papers collected here are the results of that workshop. Digital Media: Technological and Social Challenges of the Interactive World is organized in four parts, each representing a different perspective on digital media: preservation, humanities, organizational, and historical. The section on preservation considers the problems of archiving digital media for long-term preservation; the humanities section offers a human-centered view of digital media, focusing on the interaction between technological changes and cultural practices; the section dealing with organization goes beyond the study of digital artifacts in isolation to consider the context, collection, and arrangement of objects; and the historical section examines how our perspectives on digital media have changed over time, looking at how issues such as the digital divide and digital production have changed as technology has changed. The wealth of varied perspectives in Digital Media provides new light on this topic, beyond the media studies viewpoint that is the most common way of engaging these topics. This collection will be a valuable addition for students and faculty in information studies, communication studies, rhetoric, new media, and more.

This book covers the most essential techniques for designing and building dependable distributed systems, from traditional fault tolerance to the blockchain technology. Topics include checkpointing and logging, recovery-orientated computing, replication, distributed consensus, Byzantine fault tolerance, as well as blockchain. This book intentionally includes traditional fault tolerance techniques so that readers can appreciate better the huge benefits brought by the blockchain technology and why it has been touted as a disruptive technology, some even regard it at the same level of the Internet. This book also expresses a grave concern on using traditional consensus algorithms in blockchain because with the limited scalability of such algorithms, the primary benefits of using blockchain in the first place, such as decentralization and immutability, could be easily lost under cyberattacks.

Inhaltsangabe:Abstract: Even though the benefits of mobile agents have been highlighted in numerous research works, mobile agent applications are not in widespread use today. For the success of mobile agent applications, secure, portable, and efficient execution platforms for mobile agents are crucial. However, available mobile agent systems do not meet the high security requirements of commercial applications, are not portable, or cause high overhead. Currently, the majority of mobile agent platforms is based on Java. These systems simply rely on the security facilities of Java, although the Java security model is not suited to protect agents and service components from each other. Above all, Java is lacking a concept of strong protection domains that could be used to isolate agents. The J-SEAL2 mobile agent system extends the Java environment with a model of strong protection domains. The core of the system is a micro-kernel fulfilling the same functions as a traditional operating system kernel: Protection, communication, domain termination, and resource control. For portability reasons, J-SEAL2 is implemented in pure Java. J-SEAL2 provides an efficient communication model and offers good scalability and performance for large-scale applications. This thesis explains the key concepts of the J-SEAL2 micro-kernel and how they are implemented in Java.

This book contains accepted papers presented at CISIS 2020 held in the beautiful and historic city of Burgos (Spain), in September 2020. The aim of the CISIS 2020 conference is to offer a meeting opportunity for academic and industry-related researchers belonging to the various, vast communities of computational intelligence, information security, and data mining. The need for intelligent, flexible behaviour by large, complex systems, especially in mission-critical domains, is intended to be the catalyst and the aggregation stimulus for the overall event. After a thorough peer-review process, the CISIS 2020 International Program Committee selected 43 papers which are published in these conference proceedings achieving an acceptance rate of 28%. Due to the COVID-19 outbreak, the CISIS 2020 edition was blended, combining on-site and on-line participation. In this relevant edition, a special emphasis was put on the organization of five special sessions related to relevant topics as Fake News Detection and Prevention, Mathematical Methods and Models in Cybersecurity, Measurements for a Dynamic Cyber-Risk Assessment, Cybersecurity in a Hybrid Quantum World, Anomaly/Intrusion Detection, and From the least to the least: cryptographic and data analytics solutions to fulfil least minimum privilege and endorse least minimum effort in information systems. The selection of papers was extremely rigorous in order to maintain the high quality of the conference and we would like to thank the members of the Program Committees for their hard work in the reviewing process. This is a crucial process to the creation of a high standard conference, and the CISIS conference would not exist without their help.
