Abstract
A digital asset is represented and verified as a set of related digital asset or other content objects. Related metadata is stored on an immutable distributed ledger separately from the content objects themselves. For example, a transaction object includes metadata such as identifiers for two or more content objects, fingerprints for the content objects. The content objects may be stored in a local or cloud object repository. Validation of a later identified content object may include determining a fingerprint for the later identified content object, mapping that fingerprint to an address within the immutable distributed ledger to retrieve metadata previously mapped, and comparing the two fingerprints. Visual validation may be provided when the first and second fingerprints match, such as by displaying a positive icon adjacent the later identified object.
