Many reversible data hiding schemes using quantized DCT coefficient have been proposed recently. But the big problem was most of schemes could not meet the requirement of visual quality and robustness at the same time. This paper presents a reversible data hiding scheme for HEVC (High Efficiency Video Coding). The scheme toke visual quality and robustness into account after embedding. And then the mid-frequency location in the appropriate set of the 8x8 block was selected. The coefficient near to the mid-frequency would be selected to embed the secret data. The results show that this scheme has better visual quality and good robustness, and has low influence on bitrates at the same time.
