Abstract
Techniques for metadata-based information provenance are disclosed. A node in a data provisioning layer receives encrypted payload data to be delivered to a recipient. The node generates provenance metadata that describes at least one action taken by the node with respect to the encrypted payload data. The node transmits the encrypted payload data and the provenance metadata via the data provisioning layer toward the recipient.
