Secure credentialing systems and methods

1 . A method for preparing a credential record, the credential record including a credential document stored as a plurality of document chunks in a distributed ledger system, wherein the credential record includes a private safe and a credential safe, the private safe referencing documents stored in the distributed ledger systems, the distributed ledger system including a plurality of nodes, the method comprising:

accessing the credential record associated with the credential document;

retrieving the plurality of document chunks from different nodes of the plurality of nodes by requesting from a node of the plurality of nodes a document chunk from a neighbor node, the neighbor node providing the document chunk to the node;

assembling the plurality of document chunks to provide the credential document; and

assigning a document from the private safe to the credential safe.

2 . The method of claim 1 , wherein the neighbor node is randomly selected from the plurality of nodes.

3 . The method of claim 1 , wherein, when the neighbor node does not have the requested document chunk, requesting from the node the document chunk from another neighbor node.

4 . The method of claim 1 , further comprising receiving a request for the credential document.

5 . The method of claim 4 , further comprising receiving a document identifier associated with the credential document at the distributed ledger system.

6 . The method of claim 1 , further comprising decrypting each document chunk of the plurality of document chunks prior to assembling the plurality of document chunks.

7 . The method of claim 1 , further comprising checking the document against a hash to determine the document is intact.

8 . The method of claim 1 , further comprising:

accessing a document chunk map at a node of the plurality of nodes of the distributed ledger system, the document chunk map identifying and ordering the plurality of document chunks;

wherein retrieving the plurality of document chunks includes retrieving the plurality of document chunks identified in the document chunk map from different nodes of the plurality of nodes; and

assembling the plurality of document chunks includes assembling the plurality of document chunks in accordance with the document chunk map to provide the document.

9 . The method of claim 1 , further comprising:

providing access to the credential record, the credential record including information identifying a credential candidate and credential information associated with the credential candidate;

receiving the credential document, the credential document associated with the credential information; and

storing the credential document in the distributed ledger system comprising a plurality of nodes.

10 . The method of claim 9 , wherein storing the credential document includes:

dividing the credential document into the plurality of document chunks; and

distributing the plurality of document chunks to the plurality of nodes within the distributed ledger system.

11 . The method of claim 10 , wherein document chunks of the plurality of document chunks are distributed to different nodes of the plurality of nodes.

12 . The method of claim 10 , wherein distributing the plurality of document chunks to the plurality of nodes comprises:

sharing a document chunk of the plurality of document chunks with a first node of the plurality of nodes; and

sharing the document chunk from the first node of the plurality of nodes to a second node of the plurality of nodes.

13 . The method of claim 12 , further comprising sharing the document chunk to additional nodes until a number of nodes greater than a Byzantine number has received the document chunk.

14 . The method of claim 10 , further comprising encrypting the document chunks prior to storing the document chunk at a node of the plurality of nodes.

15 . The method of claim 10 , wherein storing the credential document further includes:

creating a document chunk map identifying and ordering the plurality of chunks; and

storing the document chunk map in the distributed ledger system.

16 . The method of claim 15 , further comprising storing the document chunk map at a node of the plurality of nodes when consensus about the document chunk map has been reached in accordance with a consensus protocol of the distributed ledger system.

17 . The method of claim 1 , wherein the credential document information includes primary source verification associated with the credential document.

18 . The method of claim 17 , further comprising storing the primary source verification in the distributed ledger system.

19 . The method of claim 1 , further comprising:

providing access to the credential record, the credential record including information identifying a credential candidate and credential information associated with the credential candidate; and

storing the credential information in the distributed ledger system comprising a plurality of nodes.
