Intelligent Transportation Systems (ITS) are on the rise, yet the knowledge about privacy preferences by different types of drivers in this context needs to be improved. This paper presents survey-based research (N = 528) focusing on preferences of drivers from South Africa and the Nordic countries for data processing and sharing by ITS, including future vehicular ad hoc networks. Our results indicate regionally framed drivers’ privacy attitudes and behaviours. South African participants have higher privacy concerns and risk perception. However, their preferences to share location data with police, family and friends, emergency services, and insurance companies are higher. Moreover, the region significantly affects preferences for transparency and control and sharing frequency, as well as willingness to pay for privacy, which are higher among the South Africans. We discuss how our results on factors, including region, impacting drivers’ privacy preferences can contribute to the design of usable privacy and identity management for ITS.

While recent research on intelligent transportation systems including vehicular communication systems has focused on technical aspects, little research work has been conducted on drivers’ privacy perceptions and preferences. Understanding the driver’s privacy perceptions and preferences will allow researchers to design usable privacy and identity management systems offering user privacy choices and controls for intelligent transportation systems. We conducted in-depth semi-structured interviews with 17 Swedish drivers to analyse their privacy perceptions and preferences for intelligent transportation systems, particularly for user control and for privacy trade-offs with cost, safety and usability. We also compare our results from the interviews with Swedish drivers with results from interviews that we conducted previously with South African drivers. Our cross-cultural comparison shows that perceived privacy implications, the drivers’ willingness to share location information under certain conditions with other parties, as well as their appreciation of Privacy Enhancing Technologies differ significantly across drivers with different cultural backgrounds. We further discuss the cultural impact on privacy preferences, including those for privacy trade-offs, and the implications of our results for usable privacy-enhancing Identity Management for future vehicular communication systems. In particular, we provide recommendations for suitable pre-defined privacy options to be offered to users with different cultural backgrounds enabling them to easily make privacy-related control choices.

This article presents an overview and analysis of the key cybersecurity problems, challenges and requirements to be addressed in the future, which we derived through 63 interviews with European stakeholders from security-critical sectors including Open Banking, Supply Chain, Privacy-preserving Identity Management, Security Incident Reporting, Maritime Transport, Medical Data Exchange, and Smart Cities. We show that common problems, challenges and requirements across these sectors exist in relation to building trust, implementing privacy and identity management including secure and useable authentication, building resilient systems, standardisation and certification, achieving security and privacy by design, secure and privacy-compliant data and information sharing, and government regulations. Our results also indicate cybersecurity trends and allow to derive directions for future research and innovation activities that will be of high importance for Europe.
