method designed for H.266/Versatile Video Coding (VVC)
compressed video streams. In this work, we explore two exclusive tools in H.266/VVC standard, named Multiple Transform
Selection (MTS) and Cross-component linear model (CCLM),
to embed information. These two tools are utilized to preserve
high video reconstruction quality and compression efficiency
as well as enhance embedding capacity. In specific, MTS is for
embedding information into luminance blocks by modifying
the selections of coding transforms. Comparing with other
tools, MTS has less significant impact on compression quality
and efficiency. In addition, CCLM is further used to embed
information into chrominance blocks to further enlarge the
embedding capacity with little impact on the other two metrics.
To our best knowledge, it is the first information hiding method
exclusively designed for H.266/VVC. Experimental results show
that our proposed information hiding method ensures high embedding capacity, remarkable video reconstruction quality and
insignificant impact on compression efficiency, which achieves
a better overall performances comparing to existing methods
for compressed video.
