New CFE-PPAR method enables privacy-preserving video action recognition with compression

By PulseAugur Editorial · [1 sources] ·

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.

    CFE-PPAR: Compression-friendly encryption for privacy-preserving action recognition leveraging video transformers

    arXiv:2605.05692v1 Announce Type: new Abstract: Privacy-preserving action recognition (PPAR) enables machines to understand human activities in videos without revealing sensitive visual content. Among the various strategies for PPAR, encryption-based methods achieve strong privac…
