The insurgence of smart internet-connected devices has had an unparalleled impact on modern life. On the one hand, the popularity of such devices is ever increasing because of their ability to simplify the lives of people by handling different tasks; on the other hand, they can pose several privacy and security threats to the people in their vicinity. While prior research have focused on studying the privacy and security risks of primary users of these devices, the same cannot be said for incidental users, such as bystanders or visitors. This group of users is particularly vulnerable to privacy threats because in many cases they are unknowingly recorded by smart devices and on top of that, they do not have the same privileges as that of an owner in terms of controlling these devices. In this dissertation, we explored the privacy and security risks of incidental users and made actionable design recommendations for privacy-enhancing tools for smart devices through three user studies. The studies revealed that incidental users do not trust software-based device controls, are often uncertain about when a device collects their information (or not), and apply unique privacy-enhancing techniques as workaround to protect their privacy. Based on our findings, we identified and introduced the concept of 'tangible privacy' - a combination of privacy control and feedback mechanisms that can be manipulated or perceived by touch and that provide clear confidence and certainty of privacy to people around smart devices. Using an online study, we assessed people's perceptions of privacy risk, trust, reliability, usability, and control for devices that incorporate tangible privacy mechanisms. We found that devices with tangible device controls were perceived as more trustworthy and usable than those with non-tangible mechanisms for providing strong privacy assurances to users. This thesis also explores the effectiveness and usability of tangible privacy mechanisms for managing privacy tensions between device owners and incidental users in the context of smart speakers. This dissertation lays a foundation for designing user-centric privacy-enhancing mechanisms for smart devices to address the privacy and security concerns of end users.
