Cryptographically provable data certification and provenance

摘要

A data notarization service receives a request to provide certified data to a recipient. The request may be received from the recipient or from an authorizing entity. In response to the request, the data notarization service acquires the requested data, and applies one or more selected certifications to the requested data to produce certified data. The data notarization service signs the certified data with a notarization. The certifications are selected based at least in part on certification preferences specified by the recipient, and the notarization is applied in accordance with notarization preferences specified by the recipient. The notarized and certified data is provided to the recipient in accordance with an authorization received by the authorizing entity. The authorization may impose limits on when the data is provided and the content of the data provided.
