Abstract

A method is disclosed for creating and protecting provenance metadata by means of a trusted third party that maintains the provenance metadata in a form that enables that party to underwrite both the integrity and the origin of the provenance. By providing full control of the provenance metadata, the method offers advantages over known systems that provide assurance of data integrity.
