  Due to the abrupt arise of pandemic worldwide, the video conferencing
platforms are becoming ubiquitously available and being embedded into either
various digital devices or the collaborative daily work. Even though the
service provider has designed many security functions to protect individual's
privacy, such as virtual background (VB), it still remains to be explored that
how the instability of VB leaks users' privacy or impacts their mentality and
behaviours. In order to understand and locate implications for the contextual
of the end-users' privacy awareness and its mental model, we will conduct
survey and interviews for users as the first stage research. We will raise
conceptual challenges in terms of the designing safety and stable VB, as well
as provide design suggestions.
