Anonymization Use Cases for Data Transfer in the Automotive Domain.

Nowadays, modern vehicles become more and more smart and interconnected, which leads to new paradigms and applications, such as autonomous driving. However, when it comes to data collection and sharing between vehicles or between vehicles and infrastructure or manufacturers, privacy becomes an challenge. Especially personal data should be protected from unauthorized access. To do so, anonymization should be employed which removes sensitive information before it is shared with others. In the literature, anonymization has been the focus of research in different domains, such as health, but not as much in the vehicle domain. In this paper, we propose different use cases from a large German car manufacturer to classify data collection use cases based on their requirements and challenges for anonymization.
