NFT Identity Verification Using Biometrics and Blockchain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity verification systems, particularly in the US, are fragmented and prone to identity theft and fraud due to the use of physical identity documents with varying levels of security and trustworthiness, which are difficult to verify and often require different documents for different entities, and social media account verification processes are platform-specific and limited.
Innovation Solution
The creation of NFT-based identities using blockchain technology, smart contracts, and biometric data to generate platform-agnostic, secure digital identities that can be verified across various platforms and domains, enhancing security and simplifying the identity verification process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical identity documents are used for verification, then identity verification can be performed, but the system becomes fragmented and vulnerable to fraud
Solution Approach 1:
The patent merges multiple physical identity documents and verification systems into a single unified digital identity system using NFTs. The NFT identity consolidates information from various physical ID cards, social media accounts, and other verification sources into one interoperable digital identity that can be verified across different platforms without requiring separate verification processes for each.
Solution Approach 2:
The NFT-based digital identity serves multiple verification functions across different platforms and domains. A single NFT identity can be used for social media verification, professional networking, e-commerce, and other online services, replacing the need for platform-specific verification systems and multiple physical identity documents.
2Adaptability or versatility
If multiple physical identity documents are issued to individuals, then more forms of identification are available, but security and trustworthiness vary and susceptibility to counterfeit increases
Solution Approach 1:
The patent transforms physical identity documents into digital NFT-based identities, changing the fundamental parameter of identity representation from physical to digital. This parameter change enables enhanced security through cryptographic verification, immutability on blockchain, and programmable verification rules, while maintaining the versatility of having multiple identity types represented as different NFTs.
Solution Approach 2:
The NFT identity acts as a composite structure combining multiple verification elements (personal information, biometric data, verification credentials, platform endorsements) into a single secure digital identity. This composite approach integrates various trust sources into one verifiable identity package that maintains both versatility and high security.
3Reliability
If traditional identity verification processes are used, then verification can be performed, but the process is time-consuming and requires multiple documents
Solution Approach 1:
The patent implements preliminary action by pre-verifying identity information and embedding verification credentials directly into the NFT during its creation. Biometric data, personal information, and verification authorities are authenticated in advance and stored on-chain, so that subsequent verification processes only require querying the NFT rather than re-verifying all identity attributes, significantly reducing verification time while maintaining accuracy.
Solution Approach 2:
The verification system incorporates feedback mechanisms where verification results and authentication status are immediately updated and reflected in the NFT metadata. This real-time feedback allows verifying systems to quickly determine authentication status without manual review, reducing verification time while maintaining high reliability through automated validation rules.
