This book presents a study carried out by the IEEE-SMC French chapter on ethics and digital transformation in industry and society. Based on a survey of researchers in ICT, artificial intelligence (AI), as well as on presentation seminars, this study examines the various aspects that should be considered when assessing ethical principles in approaches to digital transition, particularly with regard to intelligent systems. Considering this, Ethics and Digital Transition presents the main technologies and uses of intelligent systems. Bringing together specialists from various fields, it explores the different dimensions of ethics that should be considered in the development of these systems, from the engineering sciences to law, sociology and philosophy. It also looks at the future challenges of ethics in the digital transition.
