A method and system are provided for efficiently verifying the integrity of file-based video audio and other essence in a content production system. The method involves creating a sequence of hash codes for the editable units of the essence, which are stored as metadata apart from the content (either in a separate file or in a separate portion of the same file), and are correlated to the content by a time label (which may be an offset or a timecode number). Upon retrieval from storage, the hash codes are generated for the retrieved essence and compared to the stored hash codes to verify that the content has not been modified. |
