Region-of-interest encryption in HEVC compressed video
Yiqi Tew, KokSheik Wong, Raphaël C.‐W. Phan · 2016
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.
