Understanding Bi-Temporal Provenance – Entity Authority Corroboration

A four-timestamp attribution record for each corroboration claim: (1) original creation date, (2) date of first machine-readable publication, (3) date of authority database registration, (4) date of most recent corroboration confirmation. Bi-Temporal Provenance allows detection of false or falsified corroboration by revealing timestamp inconsistencies that indicate post-hoc data insertion. The four-timestamp structure anchors the temporal consistency chain at multiple independently verifiable points, raising the cost of retroactive false attribution. A bi-temporal provenance application of the Snodgrass-Jensen bi-temporal database concept to entity authority corroboration tracking.
