NFT-Based Notarization System for Secure Document Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system that leverages non-fungible token (NFT) technology to enhance authentication means for document notarization at electronic kiosks, such as automated teller machines, to ensure secure and verifiable notarization processes.
Innovation Solution
A system utilizing NFTs that electronically receives a document and identification credentials, crawls through a distributed ledger to determine existing NFTs, captures user signatures, generates NFTs for the signed documents, links them with identification credentials, and records these on the distributed ledger, ensuring secure and verifiable notarization by creating an evidentiary chain of custody.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used for document notarization, then the process is simple and fast, but security and verifiability are insufficient
Solution Approach 1:
The patent introduces NFTs as an intermediary mechanism between traditional authentication systems and blockchain technology. The NFT generator creates digital tokens that represent identification credentials, which then serve as verifiable intermediaries in the notarization process. This mediator enables enhanced security without requiring complete system redesign, as the NFT layer sits between existing authentication systems and the notarization function.
Solution Approach 2:
The patent replaces traditional mechanical authentication mechanisms (physical ID verification, manual signature validation) with digital NFT-based verification. Instead of relying on physical document handling and manual verification processes, the system uses cryptographic NFTs stored on a distributed ledger to authenticate identification credentials and track document provenance, thereby enhancing security while reducing manual intervention.
2Reliability
If NFT technology is integrated into the notarization system, then authentication and verification are enhanced, but the system complexity increases
Solution Approach 1:
The patent segments the notarization system into distinct functional modules: an NFT generator that creates digital tokens, a distributed ledger that stores NFTs, an NFT validator that verifies credentials, and a document processor that handles notarization. This segmentation allows each component to perform its specific function independently, making the overall complex system more manageable and easier to implement incrementally.
Solution Approach 2:
The NFT generator serves multiple functions: it creates NFTs for identification credentials, generates NFTs for signed documents, and manages the linkage between different document states. This multi-functionality reduces the need for separate specialized components, thereby managing system complexity while achieving enhanced verifiability through a single versatile NFT-based framework.
3Loss of information
If a distributed ledger is used to store NFTs, then transparency and evidentiary chain are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent uses NFTs as digital copies that represent original identification credentials and document states. Instead of storing the actual physical documents or credentials on the distributed ledger, the system creates and stores cryptographic representations (NFTs) that serve as verifiable copies. This copying approach maintains the integrity of the evidentiary chain while reducing the complexity of implementing and maintaining a distributed storage system.
Solution Approach 2:
The system performs preliminary actions by creating and registering NFTs for identification credentials before the notarization process begins. These pre-registered NFTs serve as foundational verifiable elements that can be referenced during document notarization, eliminating the need for complex real-time verification processes and simplifying the overall implementation.
4Reliability
If NFTs are generated and linked for each document, then authentication security is enhanced, but processing time and system resource consumption increase
Solution Approach 1:
The system performs preliminary actions by pre-generating and registering NFTs for identification credentials before the notarization process. When a document needs notarization, the system can quickly reference the pre-existing NFT rather than creating new ones, significantly reducing processing time while maintaining enhanced security through the NFT linkage mechanism.
Solution Approach 2:
The patent merges the authentication verification process with the document notarization process by using the same NFT infrastructure for both identification validation and document state tracking. This merging eliminates redundant processing steps and reduces overall system resource consumption, as a single NFT-based system handles multiple authentication tasks that would otherwise require separate systems.

AI summary
Systems, computer program products, and methods are described herein for implementing layered authorization platform using non-fungible tokens. The present invention is configured to electronically receive, via a user input device, a document designated for notarization and an identification credential from a user; crawl through a distributed ledger to determine a non-fungible token (NFT) for the identification credential; retrieve, from the distributed ledger, the NFT for the identification credential; capture, via the user input device, a signature of the user on the document designated for notarization to create a signed document; generate, using an NFT generator, an NFT for the signed document; link the NFT for the signed document with the NFT for the identification credential; and record the NFT for the signed document in the distributed ledger.
