Joint selective encryption and data embedding technique in HEVC video
Yiqi Tew, KokSheik Wong, Raphaël C.‐W. Phan · 2016
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 to embed data. Experiment results show that joint selective encryption and data embedding is achieved at the expense of slight bitrate overhead. Our proposed technique is able to secure video content and support data extraction in both encrypted and decrypted forms.
