Digital Privacy and Security – serie

In this book, the authors highlight the latest research findings on the security and privacy of federated learning systems. The main attacks and counterattacks in this booming field are presented to readers in connection with inference, poisoning, generative adversarial networks, differential privacy, secure multi-party computation, homomorphic encryption, and shuffle, respectively.   The book offers an essential overview for researchers who are new to the field, while also equipping them to explore this “uncharted territory.” For each topic, the authors first present the key concepts, followed by the most important issues and solutions, with appropriate references for further reading. The book is self-contained, and all chapters can be read independently. It offers a valuable resource for master’s students, upper undergraduates, Ph.D. students, and practicing engineers alike.

As "right to be forgotten" style regulations, data governance requirements, and security concerns expand worldwide, researchers and practitioners need methods that go beyond ad hoc retraining and provide effective deletion from models. Machine unlearning has emerged as a core capability for trustworthy artificial intelligence (AI), enabling trained models to remove the influence of specific data after deployment. This book offers a systematic, end to end guide to machine unlearning, from foundational problem formulations to practical design patterns for real world systems. It introduces the unlearning paradigm and key evaluation criteria, then presents a structured treatment of exact unlearning and approximate unlearning, highlighting when each is appropriate and what trade-offs arise in utility, efficiency, and reliability. A dedicated section on unlearning auditing and verification explains how to test and validate deletion claims, including protocol level schemes, model centric auditing approaches, and benchmark driven stress testing at scale. The book then extends unlearning to domain specific settings, covering graph unlearning, federated unlearning, and emerging techniques for large language models and diffusion models. Finally, it examines privacy and security risks such as leakage, backdoors, and poisoning, and surveys defenses and future directions for building dependable unlearning services. Written for graduate students, researchers, and engineers, the book provides a coherent taxonomy, practical insights, and a roadmap for developing, evaluating, and deploying unlearning in modern AI pipelines.

This book presents a comprehensive, research-driven framework for implementing cost-effective cybersecurity solutions through the integration of open-source security tools within a structured, multi-tiered defense model. Addressing the growing challenge of cybersecurity affordability, particularly for SMEs, educational institutions, and resource-constrained organizations, it offers a systematic approach to mitigating threats while ensuring scalability and resilience. The book provides empirical evaluations of security tools, real-world deployment insights, and practical implementation strategies, bridging the gap between theoretical cybersecurity principles and actionable solutions. By incorporating technical, economic, and strategic perspectives, it equips cybersecurity professionals, IT administrators, researchers, and policymakers with the knowledge to enhance security postures without incurring prohibitive costs. This publication stands out by offering a structured defense model, performance benchmarking of open-source solutions, and a forward-looking analysis of emerging threats, making it an essential resource for advancing cybersecurity resilience in financially constrained environments.
