Query: Metaverse: Security and Privacy Concerns   The term "metaverse", a three-dimensional virtual universe similar to the
real realm, has always been full of imagination since it was put forward in the
1990s. Recently, it is possible to realize the metaverse with the continuous
emergence and progress of various technologies, and thus it has attracted
extensive attention again. It may bring a lot of benefits to human society such
as reducing discrimination, eliminating individual differences, and
socializing. However, everything has security and privacy concerns, which is no
exception for the metaverse. In this article, we firstly analyze the concept of
the metaverse and propose that it is a super virtual-reality (VR) ecosystem
compared with other VR technologies. Then, we carefully analyze and elaborate
on possible security and privacy concerns from four perspectives: user
information, communication, scenario, and goods, and immediately, the potential
solutions are correspondingly put forward. Meanwhile, we propose the need to
take advantage of the new buckets effect to comprehensively address security
and privacy concerns from a philosophical perspective, which hopefully will
bring some progress to the metaverse community.
