This book, Artificial Intelligence Ethics, Cyber Technology, and Digital Justice: Social and Legal Perspectives, is the result of an interdisciplinary effort to analyze the complex interaction between technological innovation and human-centered values. It aims to explore how artificial intelligence and cyber systems influence decision-making processes, legal structures, and social dynamics, while also addressing the ethical challenges that arise from their widespread use. One of the central motivations behind this work is the recognition that technology is not neutral. Every algorithm, system, and digital platform reflects certain assumptions, values, and design choices. As such, the development and application of AI and cyber technologies must be examined not only from a technical perspective but also through ethical, legal, and social lenses. This book is structured to provide a comprehensive and systematic understanding of these issues. It begins with foundational discussions on artificial intelligence and cyber technologies, followed by an exploration of ethical frameworks and human behavior in digital environments. Subsequent chapters analyze digital justice, legal systems, cybersecurity, and global policy challenges, ultimately offering a forward-looking perspective on the future of digital society. A key theme throughout the book is the importance of a human-centered approach. While technological systems continue to evolve, the human factor remains central to both opportunities and risks in the digital age. Issues such as cyberpsychology, social engineering, misinformation, and digital vulnerability demonstrate that the effectiveness of technology depends largely on how it is used and understood by individuals. This work is intended for a diverse audience, including researchers, students, policymakers, cybersecurity professionals, and anyone interested in the broader implications of digital transformation. By integrating perspectives from social sciences, law, and technology, the book seeks to contribute to ongoing academic discussions and provide practical insights for real-world applications.
