Abstract
In the current automotive ecosystem, the trend of pairing mobile devices to connected vehicles is gaining momentum, providing a vast number of benefits such as hands-free driving and remote vehicle control. However, along with these conveniences arises the issue of data accumulation, ranging from vehicle diagnostics to personal identifiable information (PII). The problem emerges when a consumer rents a vehicle, pairs their mobile device to the infotainment system, and neglects to remove their device prior to returning the vehicle. This oversight can potentially expose vulnerabilities with the current renter’s PII for subsequent renters to exploit. Research indicates that renters often overlook the deletion process prior to returning the rental vehicle and are unaware of whose responsibility it is to perform this task. In this survey, we investigated the experiences and perceptions of a group of consumers who have previously rented vehicles. We wanted to know if the participants were aware they were responsible for deleting their mobile device from the rental vehicle before returning it, the renters’ importance and tolerance for risk if they overlooked the deletion process leaving their shared data on the infotainment system for subsequent users, and if they were aware who was responsible for deleting their shared data. Lastly, we explored if the participants supported an automated solution to perform this manual deletion process. The goal of this paper is to demonstrate the significance of safeguarding PII in connected vehicles and advocate for the adoption of an automated solution to mitigate this privacy risk.
