Privacy-preserving document sharing

Abstract:

An example operation may include one or more of sending, by a user node, a document request comprising a document identifier (ID) to a document processor node connected over a blockchain, receiving, by the user node, a one-time pass-code from the document processor node based on the document ID, linking to the document using the one-time pass-code, and retrieving the document from a document owner node.
