The ubiquitous presence of smart devices along with advancements in\nconnectivity coupled with the elastic capabilities of cloud and edge systems\nhave nurtured and revolutionized smart ecosystems. Intelligent, integrated\ncyber-physical systems offer increased productivity, safety, efficiency, speed\nand support for data driven applications beyond imagination just a decade ago.\nSince several connected devices work together as a coordinated unit to ensure\nefficiency and automation, the individual operations they perform are often\nreliant on each other. Therefore, it is important to control what functions or\nactivities different devices can perform at a particular moment of time, and\nhow they are related to each other. It is also important to consider additional\nfactors such as conditions, obligation or mutability of activities, which are\ncritical in deciding whether or not a device can perform a requested activity.\nIn this paper, we take an initial step to propose and discuss the concept of\nActivity-Centric Access Control (ACAC) for smart and connected ecosystem. We\ndiscuss the notion of activity with respect to the collaborative and\ndistributed yet integrated systems and identify the different entities involved\nalong with the important factors to make an activity control decision. We\noutline a preliminary approach for defining activity control expressions which\ncan be applied to different smart objects in the system. The main goal of this\npaper is to present the vision and need for the activity-centric approach for\naccess control in connected smart systems, and foster discussion on the\nidentified future research agenda.\n
