Abstract

Methods and systems for controlled data sharing are provided. A method includes: communicating, as a first node of a supply chain distributed ledger, with a second node and a third node of the ledger, the nodes corresponding to a first entity, a second entity, and a third entity in a supply chain; storing, with a data management module, a hash of a public version of a contract between the first entity and the second entity; replicating the hash of the public version of the contract to the ledger; sharing a private version of the contract between the first and second nodes; storing a hash of a public version of a purchase order between the first entity and the third entity; replicating the hash of the public version of the purchase order to the ledger; and sharing a private version of the purchase order between the first and third nodes.

Claims20

Dependent claims

A system for controlled data sharing comprising:

a network interface;
a user interface device;
and
a control circuit coupled to the network interface and the user interface device, the control circuit executing a data management module configured to:
communicate, as a first node of a supply chain distributed ledger and via the network interface, with a second node and a third node of the supply chain distributed ledger, the nodes corresponding to a first entity, a second entity, and a third entity in a supply chain;
store a hash of a public version of a contract between the first entity and the second entity at the first node;
replicate the hash of the public version of the contract to the supply chain distributed ledger, the public version of the contract being accessible to all of the entities;
share a private version of the contract between the first and second nodes, the private version of the contract being shared peer-to-peer between, and accessible by, only the first and second entities;
store a hash of a public version of a purchase order between the first entity and the third entity at the first node;
replicate the hash of the public version of the purchase order to the supply chain distributed ledger, the public version of the contract being accessible to all of the entities;
and
share a private version of the purchase order between the first and third nodes, the private version of the contract being shared peer-to-peer, and accessible by, only the first and third entities.

storing, with a control circuit executing a data management module, a hash of a public version of a contract between the first entity and the second entity at the first node;
replicating, by the control circuit, the hash of the public version of the contract to the supply chain distributed ledger, the public version of the contract being accessible to all of the entities;
sharing, by the control circuit, a private version of the contract between the first and second nodes, the private version of the contract being shared peer-to-peer between, and accessible by, only the first and second entities;
storing, by the control circuit, a hash of a public version of a purchase order between the first entity and the third entity at the first node;
replicating, by the control circuit, the hash of the public version of the purchase order to the supply chain distributed ledger, the public version of the contract being accessible to all of the entities;
and
sharing, by the control circuit, a private version of the purchase order between the first and third nodes, the private version of the contract being shared peer-to-peer, and accessible by, only the first and third entities.
