An HEVC format-compliant joint selective encryption and data embedding technique is proposed. The proposed technique is separable, where the decryption and data extraction processes are independent, with minimal parsing overhead. Specifically, elements in the HEVC coding structure are divided into two groups, where one group is manipulated to perceptually mask the video content, while another is modified...
In this work, three encryption techniques are proposed by manipulating the bin (binary symbol) of significant values, transform skip signals and suffixes in selected CTU (coding tree unit) of video slices under the HEVC standard. These techniques are applied with minimal parsing overhead during encoding and decoding processes. Experiment results show that the selected region can be sufficiently encrypted.
