proof of authorship

Definition​

Proof that somebody or something has originally created certain content. It's about data's inception. Whereas proof-of-authority is about rights attached to this data.

For example, a signature constitutes direct proof of authorship; less directly, handwriting analysis may be submitted as proof of authorship of a document.[21] Privileged information in a document can serve as proof that the document's author had access to that information; such access might in turn establish the location of the author at certain time, which might then provide the author with an alibi.

ACDC and proofs​

Proof of authorship and proof of authority are integrated in Authentic Chained Data Containers (ACDCs) constituting an Authentic Provenance Chain (APC):

  • ACDCs provide a verifiable chain of proof-of-authorship of the contained data
  • A proof-of-authority may be used to provide verifiable authorizations or permissions or rights or credentials. A chained (treed) proof-of-authority enables delegation of authority and delegated authorizations. These proofs of authorship and/or authority provide provenance of an ACDC itself and by association any data that is so conveyed.

Example APC : book rights sold​

The data contained in an ACDC is a book written by Terlalu Bonito; the ACDC also contains anchoring digest, signed by the author at publishing date. Terlalu has sold all rights to publish the book to Liz Smiley The ownership of the book matches the current control over the book and its digital twin: the proof of authority by the chain of ACDCs.
