The source of health care data is an important attribute to be tracked and validated. Therefore 1upHealth's API platform includes additional features to track data provenance and assure it's integrity. Automatically, whenever data is inserted into 1upHealth or collected from any of the connected health systems, a FHIR® provenance resource is created detailing the time, location, and attributed resource location. In addition to the basic FHIR® provenance resource, the signature field contains a hash or the linked resource. That hash can be verified against a public ledger running on a side chain or Ethereum. That way anyone who receives the resource can verify that the data they have has not been tampered with and is clinical grade so it can be trusted to make critical decisions.
