AB  - Today, High Efficiency Video Coding (HEVC), developed by the ITU-T video coding experts group
and ISO/IEC moving picture experts group is emerging as a potential video compression standard. HEVC or
H.265 compared to H.264/AVC is primarily standardized to improve the compression ratio, so as to achieve an
equivalent video quality. In HEVC, a joint selective encryption and data embedding technique is proposed
where HEVC coding structure is separated into two groups. One is utilized for encrypting video content and
the other for embedding data. However, the size of bit-streams for encrypted and data-embedded videos are
increased significantly, since, the HEVC coding structure is not utilized. Therefore, in this study we have
proposed an improved joint selective encryption and matrix embedding technique using block size coding
decision model in H.265. In this approach, non-zero DCT coefficients are manipulated according to the
transform block size in all frames. Here, matrix embedding is proposed in terms of large payloads for improving
embedding efficiency and reducing coding complexity. The results obtained show that the proposed data
hiding technique for H.265 provided highest embedding efficiency with reduced coding complexity.
