Abstract

The NFT Based Secure Authentication and Notification Apparatuses, Processes and Systems (“NBSA”) transforms authenticating NFT generation input, NFT authentication input, document publishing input, NFT document access input datastructure/inputs via NBSA components into authenticating NFT generation output, NFT authentication output, document publishing output, NFT document access output outputs. A document publishing request datastructure structured to specify a set of document info fields associated with a document is obtained. A hash of the set of document info fields is generated. A document object associated with the document is stored. A document publishing transaction structured to facilitate storing publication information regarding the document is submitted to a blockchain. An NFT metadata datastructure structured to specify the document identifier and an identifier of the document publishing transaction is generated. A set of subscribers for the document is determined. For each respective subscriber, a notification NFT is minted and a subscriber notification message is sent.

First claim

What is claimed is:

1. An NFT-based document publication notification message generating apparatus, comprising:
at least one memory;
a component collection stored in the at least one memory;
at least one processor disposed in communication with the at least one memory, the at least one processor executing processor-executable instructions from the component collection, the component collection storage structured with processor-executable instructions, comprising:
obtain, via the at least one processor, a document publishing request datastructure structured to specify a set of document info fields associated with a document, in which the set of document info fields includes a document identifier and document contents;
generate, via the at least one processor, a hash of the set of document info fields associated with the document;
store, via the at least one processor, a document object associated with the document in an adjunct repository, in which the document object is structured to specify the set of document info fields and the hash;
submit, via the at least one processor, a document publishing transaction to a blockchain, in which the document publishing transaction is structured to facilitate storing publication information regarding the document via the blockchain, in which the publication information includes the hash;
generate, via the at least one processor, an NFT metadata datastructure structured to specify the document identifier and an identifier of the document publishing transaction;
determine, via the at least one processor, a set of subscribers for the document;
mint, via the at least one processor, for each respective subscriber in the set of subscribers, a notification NFT by sending a blockchain transaction to a document publication notification generating smart contract deployed on the blockchain, in which the document publication notification generating smart contract is structured to associate the generated NFT metadata datastructure and a subscriber blockchain address associated with the respective subscriber with the notification NFT; and
send, via the at least one processor, for each respective subscriber in the set of subscribers, a subscriber notification message for the respective subscriber via a communication method specified for the respective subscriber, in which the subscriber notification message is structured to specify an identifier associated with a notification NFT minted for the respective subscriber.

2. The apparatus of claim 1 , in which the document is one of: a text file, a markup language file, a data interchange file, a binary file, a database record.

3. The apparatus of claim 1 , in which the set of document info fields includes at least one of: a current document version, a previous document version.

4. The apparatus of claim 3 , in which the component collection storage is further structured with processor-executable instructions, comprising:
determine, via the at least one processor, a set of changes between the current document version of the document and the previous document version of the document; and
in which the hash is generated also based on the set of changes.

5. The apparatus of claim 1 , in which the hash is generated via a cryptographic hash function applied to the set of document info fields associated with the document.

6. The apparatus of claim 1 , in which the document object is stored in the adjunct repository such that the hash is utilized as a key to the document object in the adjunct repository.

7. The apparatus of claim 1 , in which the document publishing transaction is sent to the blockchain.

8. The apparatus of claim 7 , in which the document publishing transaction is sent to a document publishing smart contract deployed on the blockchain, in which the document publishing smart contract is structured to emit a document publication event upon receiving the document publishing transaction, and in which the document publication notification generating smart contract is structured to listen for document publication events from the document publishing smart contract.

9. The apparatus of claim 1 , in which a subscriber in the set of subscribers comprises a plurality of entities.

10. The apparatus of claim 1 , in which the set of document info fields includes a document publication state, and in which the set of subscribers is determined based on the document publication state.

11. The apparatus of claim 1 , in which a subscriber notification message is structured to specify a link that facilitates access to the document.

12. The apparatus of claim 11 , in which the link is structured to include the hash.

13. The apparatus of claim 1 , in which a subscriber blockchain address is a blockchain wallet address.

14. The apparatus of claim 1 , in which the document publication notification generating smart contract is structured as a smart contract implementing ERC-721 standard.

15. The apparatus of claim 1 , in which the blockchain is one of: Solana, Ethereum, Polygon.

16. An NFT-based document publication notification message generating processor-readable, non-transient medium, the medium storing a component collection, the component collection storage structured with processor-executable instructions comprising:
obtain, via the at least one processor, a document publishing request datastructure structured to specify a set of document info fields associated with a document, in which the set of document info fields includes a document identifier and document contents;
generate, via the at least one processor, a hash of the set of document info fields associated with the document;
store, via the at least one processor, a document object associated with the document in an adjunct repository, in which the document object is structured to specify the set of document info fields and the hash;
submit, via the at least one processor, a document publishing transaction to a blockchain, in which the document publishing transaction is structured to facilitate storing publication information regarding the document via the blockchain, in which the publication information includes the hash;
generate, via the at least one processor, an NFT metadata datastructure structured to specify the document identifier and an identifier of the document publishing transaction;
determine, via the at least one processor, a set of subscribers for the document;
mint, via the at least one processor, for each respective subscriber in the set of subscribers, a notification NFT by sending a blockchain transaction to a document publication notification generating smart contract deployed on the blockchain, in which the document publication notification generating smart contract is structured to associate the generated NFT metadata datastructure and a subscriber blockchain address associated with the respective subscriber with the notification NFT; and
send, via the at least one processor, for each respective subscriber in the set of subscribers, a subscriber notification message for the respective subscriber via a communication method specified for the respective subscriber, in which the subscriber notification message is structured to specify an identifier associated with a notification NFT minted for the respective subscriber.

17. An NFT-based document publication notification message generating processor-implemented system, comprising:
means to store a component collection;
means to process processor-executable instructions from the component collection, the component collection storage structured with processor-executable instruct
