PriCheck - An Online Privacy Assistant for Smart Device Purchases
In CHI EA '22: Extended Abstracts of the 2022 CHI Conference on Human Factors in Computing Systems. May 02, 2022. Association for Computing Machinery, New York, NY, USA. (bib)

In this paper, we present PriCheck, a browser extension that provides privacy-relevant information about smart devices (e.g., in an online shop). This information is oftentimes hidden, difficult to access, and, thus, often neglected when buying a new device. With PriCheck, we enable users to make informed purchase decisions. We conducted an exploratory study using the browser extension in a simplified (mock) online shop for smart devices. Participants chose devices with and without using the extension. We found that participants (N = 11) appreciated the usability and available information of PriCheck, helping them with informed decisions for privacy-preserving products. We hope our work will stimulate further discussion on how to make privacy information for novel products available, understandable, and easy to access for users.
