A method of distributed management of electronic documents of title (edt) and system thereof

摘要

There are provided decentralized system and method of managing electronic documents of title (EDTs). The method comprises: by an issuing node: generating a root unique object (RUO) associated with the issuing node and usable as a pointer to a blockchain maintained in the DTDB, thereby initiating for a given EDT a possession chain characterized by ID associated with the RUO (RUOID); and embedding into the given EDT a data object informative of the RUOID, and digitally signing the EDT with the embedded data object in a manner enabling an authorized holding node to verify the EDT and to extract the data object, thereby giving rise to a generated EDT; by each holding node currently being in possession of the generated EDT: transferring possession of the generated EDT to a recipient holding node being the next node to become in possession of the generated EDT, the transferring possession comprises: obtaining from the blockchain a first unique object generated by a holding node which has transferred EDT possession to the first holding node; using the first unique object to generate a second unique object which is indicative of the first unique object, specifies the recipient holding node and is includable in the blockchain; enabling including the generated next unique object into the blockchain; and forwarding the generated EDT to the recipient holding node via a digital media; by each holding node, responsive to receiving possession of the generated EDT: validating the received generated EDT; using RUO_ID embedded in the generated EDT to validate possession chain; and transferring possession of the generated EDT to recipient holding node.
