While Artificial Intelligence (AI) has already brought disruptive changes to public health (PH), the effective deployment of AI technologies requires an interdisciplinary approach to address ethical, legal, societal, and security challenges. This chapter aims to provide PH experts with a common understanding of AI and the terminology to facilitate interdisciplinary collaborations. Furthermore, this chapter highlights the potential of AI for the field of PH, particularly the emerging field of digital public health (DiPH). For this purpose, the chapter briefly introduces the concepts of AI and its applications through actual examples from DiPH. Thereafter, a critical perspective is presented on ensuring AI deployment in DiPH while adhering to ethical regulations. To demonstrate how an AI intervention can be responsibly implemented, a tablet-based activation system for people with dementia is used as an example.
