A Review of Passenger Digital Information Privacy Concerns in Smart Airports

There is an increasing interest in the use of various digital technologies for interacting with passengers at smart airports. However, there is a need to identify and address the privacy issues that may threaten passenger's digital information during their interactions with smart airports applications. This study applies a systematic literature review method and reports the passenger's digital information privacy issues that arise during different stages of their travel journey in smart airports. This research identified a set of 324 studies, which were then reviewed to obtain a final set of 31 relevant studies to address the research questions in hand. The review results were organized into five major categories: passenger travel journey through smart airports applications; elements involved (people, process, information, and technology) in the journey; passenger's digital information privacy challenges; current solutions for identified challenges; passenger's information standards and privacy regulations. These results are further analyzed to report important insights and future research directions about the privacy of passenger's digital information in smart airports. This study will aid researchers and practitioners in obtaining a better understanding of the privacy concerns when dealing with the passenger's digital information at the digitally enabled smart airports.
