Smart home IoT devices collect data not only from owners of the devices, but also from bystanders in a smart home (e.g., visiting family members, friends, or domestic workers). Existing research mainly considered the privacy concerns of bystanders from their own perspectives. In this paper, we design and conduct a survey study to more comprehensively explore the privacy concerns of bystanders from the perspectives of both owners and bystanders. For owners, we investigate their understanding of their own data practices, their views on bystanders’ privacy, and their willingness to negotiate data practices with bystanders. For bystanders, we investigate their privacy concerns, their expectations of disclosures by owners, and their willingness to share their data with owners. We recruited 200 owners and 100 bystanders. We found that most owners of smart homes recognize the privacy rights of bystanders, do not fully understand their own data practices, and are willing to address the privacy concerns of trusted bystanders. We also found that most bystanders have concerns about their privacy in other people’s smart homes, do not expect owners to disclose data practices, and are willing to share data about them with owners if they consent. Reaching a temporary agreement about data practices between owners and bystanders might require some negotiation. So, we also explore the willingness of owners and bystanders on negotiating data collection, storage, and sharing in smart homes. We found that many owners and bystanders have different preferences regarding negotiating data practices. Based on our findings, we provide recommendations for enhancing the privacy protection in smart homes.

Increasing Users’ Privacy Awareness in the Internet of Things: Design Space and Sample Scenarios

An increasing number of devices and sensors in the environments we access daily are capable of collecting personal data about us. Surveillance cameras in public spaces, smart speakers in friends’ living rooms, or smartphones carried by individuals are just a few examples. At the same time, many users are unaware of sensors being in place, in particular, those deployed in unfamiliar environments. Hence, it becomes increasingly challenging for users to keep control over their personal data being tracked and/or processed. Crucially, for users to be able to make informed decisions and privacy choices, they first of all need to be aware of potential privacy intrusions in their surroundings. In this chapter, we address this by exploring means to increase users’ privacy awareness in the Internet of Things. In particular, we illustrate the design space for such privacy awareness mechanisms, including what information should be displayed, and how this information can be made accessible for various target groups such as (to-be) device owners or passers-by. We also introduce and compare three sample scenarios in which privacy awareness mechanisms can support users: (1) privacy-relevant information for purchase decisions, (2) on-demand privacy-relevant information for active device search, and (3) in situ privacy-relevant information and guidance. The chapter is complemented by a discussion on future approaches to raising privacy awareness.
