  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.
