An improved system is described for verifying video content integrity using digital watermarking. Current verification systems using the digital signature are unable to distinguish between attacks and regular modifications such as resizing and MPEG encoding and are thus unsuitable countermeasures against actual threats to content kept in storage services. The proposed verification system distinguishes attacks against video content from regular modifications by extracting timecodes and header hash values embedded in the content itself and comparing them with the actual ones, making it well suited for content storage services. Evaluation showed that the system is more effective than a current one using the digital signature scheme and that it can be used by a variety of applications using stored video content
