An In-depth Review of Privacy Concerns Raised by the COVID-19 Pandemic.

COVID-19 has hugely changed our lives, work, and interactions with people. With more and more online activities, people are easily exposed to privacy threats. In this paper, we explore how users self-disclose on social media and privacy concerns raised from these behaviors. Based on recent news, techniques, and research, we indicate three increasing privacy threats caused by the COVID-19 pandemic. After that, we provide a systematic analysis of potential privacy issues related to the COVID pandemic. Furthermore, we propose a series of research directions about online user self-disclosure and privacy issues for future work as well as possible solutions.
