Lens Privacy Sealing: A New Benchmark and Method for Physical Privacy-Preserving Action Recognition
Researchers have developed Lens Privacy Sealing (LPS), a novel hardware solution to protect privacy in RGB camera surveillance systems. LPS uses adjustable laminating film to physically obscure camera lenses, offering pre-sensor privacy protection at a low cost. To address the video degradation caused by LPS, they also introduced MSPNet, a framework that includes an Inter-Frame Noise Suppressor and Cross-Frame Semantic Aggregator, significantly improving action recognition accuracy while suppressing identity recognition.
