ATOMIC CAPTURE USING A DISTRIBUTED LEDGER, FOR PROOF OF AUTHENTICITY AND/OR REAL TIME VISUAL VALIDATION

摘要

Techniques for proving authenticity of data files, such as digital photos. An authentication/indexing server content from a client device such as a mobile device, and generates or receives other related data such as a reference to the content object, a fingerprint for the content object, and other metadata indicating for example a timestamp related to the content object. The fingerprint is inserted into a distributed ledger, with the distributed ledger returning a ledger address. A manifest object containing the transaction object, the ledger address, and a list of the content object and, optionally, related edits is then created and stored. The server may index fingerprints. Thus, a fingerprint can be used to authenticate subsequently received object against the stored metadata. Digital assets may be represented and verified as a set of related digital assets or other content objects.
