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.
