Researchers have introduced CFE-PPAR, a novel method for privacy-preserving action recognition in videos that remains effective even after compression. Unlike previous approaches that suffer significant performance degradation when encrypted videos are compressed, CFE-PPAR allows video transformers to directly recognize encrypted content. This is achieved by using parameters transformed with the same keys used for video encryption, demonstrating superior performance on the UCF101 and HMDB51 datasets under common compression standards like Motion-JPEG and H.264.
