This Special Issue on cryptography and information security presents a diverse range of contributions, offering valuable insights into various facets of the field. The topics covered include surveying physical unclonable functions for authentication, communication protocols, challenges, and applications of Internet of Things security. Additionally, this issue discusses the development of a symmetric encryption solution derived from a binary-tree-fed mixed-network protocol, a novel deduplication method for cloud preservation with real-time ownership organization and optimization, and a low-intervention security model aimed at alleviating enterprise burdens through API utilization. Other contributions explore architectures designed to prevent low-rate denial-of-service attacks within drone environments, propose IoT-enabled lightweight authentication frameworks, and investigate the effects of long-range dependence on temporal resolution recovery in HEVC compressed-content environments. Furthermore, this issue introduces a novel framework utilizing API-based obfuscation techniques and discusses the secure application of medical IoT systems, lightweight cipher mechanisms for electronic commerce transactions, and a systematic review of information security in chatbots. Together, these contributions offer valuable insights into cryptography and information security, spanning from encryption solutions to IoT-enabled authentication architectures and beyond.

This anthology contributes to creating awareness on how digital ageism operates in relation to the widely spread symbolic representations of old and young age around digital technologies, the (lack of) representation of diverse older individuals in the design, development, and marketing of digital technologies and in the actual algorithms and datasets that constitute them. It also shows how individuals and institutions deal with digital ageism in everyday life. In the past decades, digital technologies permeated most aspects of everyday life. With a focus on how age is represented and experienced in relation to digital technologies leading to digital ageism, digitalisation’s reinforcement of spirals of exclusion and loss of autonomy of some collectives is explored, when it could be natural for a great part of society and represent a sort of improvement. The book addresses social science students and scholars interested in everyday digital technologies, society and the power struggles about it, providing insights from different parts of the globe. By using different methods and touching upon different aspects of digital ageism and how it plays out in contemporary connected data societies, this volume will raise awareness, challenge power, initiate discussions and spur further research into this field.

This open access book begins with an algorithm–a set of IF…THEN rules used in the development of a new, ethical, video surveillance architecture for transport hubs. Readers are invited to follow the algorithm over three years, charting its everyday life. Questions of ethics, transparency, accountability and market value must be grasped by the algorithm in a series of ever more demanding forms of experimentation. Here the algorithm must prove its ability to get a grip on everyday life if it is to become an ordinary feature of the settings where it is being put to work. Through investigating the everyday life of the algorithm, the book opens a conversation with existing social science research that tends to focus on the power and opacity of algorithms. In this book we have unique access to the algorithm’s design, development and testing, but can also bear witness to its fragility and dependency on others.
