A Systematic Survey of Empirical User Studies of Unintentional Information Disclosure in Everyday Digital Interaction

The exchange of personal information in digital environments poses significant risks, including identity theft, privacy breaches, and data misuse. Addressing these challenges requires a deep understanding of user behavior and mental models in diverse contexts. This paper presents a systematic literature review of empirical user studies on unintentional information disclosure in usable security, covering 101 papers published across six leading conferences from 2018 to 2023. The studies are categorized based on methodologies-quantitative and qualitative-and analyzed for their applications in various scenarios. Major subtopics, including data privacy, security in browsers, and privacy tools, are examined to highlight research trends and focal areas. This review provides details on topics and application areas that have received the most research attention. Moreover, by comparing descriptive and experimental approaches, findings aim to guide researchers of strategies to mitigate risks associated with online everyday interaction.
