Anonymization for Skeleton Action Recognition. (arXiv:2111.15129v2 [cs.CV] UPDATED)

Skeleton-based action recognition attracts practitioners and researchers due
to the lightweight, compact nature of datasets. Compared with RGB-video-based
action recognition, skeleton-based action recognition is a safer way to protect
the privacy of subjects while having competitive recognition performance.
However, due to improvements in skeleton estimation algorithms as well as
motion- and depth-sensors, more details of motion characteristics can be
preserved in the skeleton dataset, leading to potential privacy leakage. To
investigate the potential privacy leakage from skeleton datasets, we first …
