Abstract: Provided is a system and method for safeguarding digital objects consisting of digital assets. The system includes a unique identifier in each digital asset and a database with a record of each unique identifier, the database further structured and arranged to correlate at least two digital assets as distinctly related. A client is in communication with the database. The client is adapted to receive a subset of the digital assets and analyze each digital asset to determine the unique identifier embedded therein. The client is further adapted to query the database with the determined unique identifier to validate each digital asset, the validation further including confirmation of distinctly related digital asset received. An associated method is also provided.
