Lens Privacy Sealing: A New Benchmark and Method for Physical Privacy-Preserving Action Recognition
Presents Lens Privacy Sealing as a pre-sensor hardware privacy method, introduces the P3AR dataset with privacy annotations, and proposes MSPNet with IFNS and CFSA modules that nearly double action recognition accuracy on degraded videos while keeping identity recognition low.
