AI has contributed a lot and biometrics is no exception. To make AI solutions commercialized
fully functional one requires trustworthy and explainable AI (XAI) solutions while respecting
ethical issues. Within the scope of biometrics the book aims at both revisiting ethical AI
principles by taking into account state-of-the-art AI-guided tools and their responsibilities
i.e. responsible AI. With this the long-term goal is to connect with how we can enhance
research communities that effectively integrate computational expertise (with both
explainability and ethical issues). It helps combat complex and elusive global security
challenges that address our national concern in understanding and disrupting the illicit
economy.
