N2 - A method is described that verifies video content integrity by checking the continuity of embedded timecodes used as digital watermarks. Conventional verification methods using digital signatures and fragile watermarking are unable to distinguish between attacks and regular modifications due and thus are unable to protect against threats to content. The proposed verification method distinguishes attacks against video content from regular modifications by extracting timecodes embedded in consecutive frames of the content and then checking their continuity. A prototype implementation showed that the method is more effective than conventional ones and that it can be used by a variety of applications using video content.
