Robustness Security of Data Hiding for H.265/HEVC Video Streams

In the current age of IoT and Industry 4.0, vast amounts of big data are exchanged in the cloud, social media and among sensing devices, at times causing videos to go viral and proliferating fake news. Ultra high quality videos such as in the latest H.265/HEVC standard format have the capacity for data to be embedded in them for different security applications. Security for high quality videos is a concern in our current technological age where netizens often share videos with others through social media and video hosting sites like YouTube. In this paper, we focus on data hiding for H.265/ HEVC and perform detailed security analysis of a recent H. 265/HEVC data hiding scheme. Our security consideration includes the hiding properties of secrecy and undetectability, as well as the robustness security property of tamper resistance. We show specifically an attack against the robustness security of this data hiding scheme. We discuss reasons causing the insecurity against robustness and justify strategies to improve the scheme’s protection against these types of attacks
