Content authentication and validation via multi-factor digital tokens, systems, and methods

A digital publication validation system, the system comprising:

• at least one computer-readable memory storing digital work authentication software instructions;
• at least one processor coupled with the at least one computer readable memory and that performs the following upon execution of the digital work authentication software instructions;
• receiving at least one authentication token that is attached to a digital publication, wherein the at least one authentication token enables validation of authenticity and provenance of the digital publication, and wherein the at least one authentication token comprises a reproduceable output of a deterministic function;
• determining a set of deterministic features from the at least one authentication token and the digital publication, wherein the set of deterministic features comprises a difference, metric that describes a difference between the at least one token and the digital publication;
• normalizing the difference metric;
• calculating a validation score as a function of the normalized difference metric and relative to an archived verification token, wherein a publication of the token/work pair is recorded on a notarized ledger;
• determining a validation of the at least one authentication token and the digital publication as a valid token/work pair based on a satisfaction of a validation criteria by the validation score;
• and
• triggering a device to take an action based on the validation.
