Towards trustworthy smart cyber-physical-social systems in the era of Internet of Things

The advent of a new wave of computing driven by the Internet of Things (IoT) and Big Data is reshaping the landscape of engineering systems design, operations, and management. As traditional devices and systems are transforming into smart devices and smart cyber-physical systems powered by IoT, more and more applications of Internet of Things are emerging as complex systems of smart systems, such as smart cities, in which an entity (including both human, software, and machines) highly relies on other entities in a network with respect to security, privacy, trustworthiness of data / information, and trustworthiness of services. Trust is emerging as a critical factor in systems design, operations and management. In this paper, we use Smart and Connected Senior Caring Systems as driving application, to discuss the features of Cyber-Physical-Social Smart Systems (CPS3) powered by IoT, to address the needs of trust in CPS3 design, and to explore approaches of trust formalisms for CPS3 design.
