Digital signatures for trustworthy authentication of elementary video streams

This paper introduces a method for digitally signing and verifying elementary video bitstreams. The method verifies temporal consistency of the video while allowing random access into the bitstream and adaptation to temporal and spatial scalability including sub-bitstream extraction. It was adopted by the Joint Video Experts Team (JVET) into the Versatile supplemental enhancement information messages for coded video bitstreams (VSEI) specification version 4 by introducing three new Digitally Signed Content SEI messages.
