Digital video has become increasingly susceptible to spatio-temporal manipulations as a result of recent advances in video editing tools.Therefore it is difficult to get video records to stand up as 100% secure evidence in court, for example for a criminal evidence.In this paper, we propose a novel digital video authentication approach based on a secure self-embedding technique.Our approach allows authentication of the origin of the video data from the embedded information after reasonable spatial manipulations.In addition, temporal manipulations can also be detected using our approach.
