Real-Time Selective Encryption Solution based on ROI for MPEG-A Visual Identity Management AF
Résumé
As part of a new MPEG-A standardization activity, called Visual Identity Management Application Format
(VIMAF), this paper presents an end-to-end encryption solution of Region of Interest (ROI) in both AVC and HEVC encoded
streams for privacy protection applications. This solution uses a selective encryption method that encrypts only the most sensitive information of the video and proposes a new adapted syntax in order to facilitate interoperability between equipments. Objective video quality measurements have shown the robustness of the proposed selective encryption solution with only a slight bitrate increase.
