NFT-Based Biometric Authentication in Distributed Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed resource networks face challenges in secure authentication due to the need for multiple usernames and passwords across different entities, leading to increased hacking risks and user credential management difficulties.
Innovation Solution
A system that creates a non-fungible token (NFT) based on a user's physical characteristics, which can be shared across multiple entities, allowing for secure unified login credentials and reducing the risk of unauthorized access by storing personal data outside individual nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users maintain multiple usernames and passwords across different entities, then authentication can be performed across distributed networks, but security risks increase and user credential management becomes difficult
Solution Approach 1:
The patent implements a universal authentication system where a single biometric template stored in a distributed hash table (DHT) can be used across multiple different entities and networks. The biometric template serves as a universal credential that enables authentication without requiring users to maintain separate credentials for each entity, thereby improving security while maintaining adaptability across distributed networks.
Solution Approach 2:
The patent introduces a distributed hash table (DHT) as an intermediary system that stores biometric templates and enables authentication across different entities. The DHT acts as a mediator between users and multiple entities, allowing secure credential management without requiring users to directly manage multiple passwords or usernames across different networks.
2Reliability
If multiple usernames and passwords are required for different entities, then access control can be maintained, but user credential management difficulty increases
Solution Approach 1:
The biometric template stored in the DHT serves as a universal credential that can be used for access control across multiple different entities. Users only need to provide their biometric data once, and the system automatically handles authentication for all entities, eliminating the need to manage multiple usernames and passwords while maintaining robust access control.
Solution Approach 2:
The system performs self-service authentication by automatically retrieving and verifying biometric templates from the DHT without requiring user intervention in credential management. The system handles the complexity of credential storage, retrieval, and verification across multiple entities, allowing users to simply provide their biometric data for authentication.
3Speed
If personal data is stored on individual nodes, then authentication can be processed locally, but risk of data breaches increases
Solution Approach 1:
The distributed hash table (DHT) serves as a decentralized intermediary that stores biometric templates across multiple network nodes rather than on a single centralized server. This distribution eliminates single points of failure and reduces data breach risk, as attackers would need to compromise multiple nodes to access stored biometric data. The DHT maintains fast authentication processing by enabling efficient peer-to-peer queries.
Solution Approach 2:
The patent segments the storage of personal data (biometric templates) across multiple individual nodes in the distributed network. Instead of storing all user data on a single centralized system, the data is divided and stored on separate nodes, making it more resistant to data breaches. Each node stores only a portion of the data, and the system reconstructs the full authentication capability by querying multiple nodes.

AI summary
Systems, computer program products, and methods are described herein for providing authentication across a distributed resource network. The method includes receiving an authentication request associated with a user. The authentication request includes one or more potential physical characteristics. The method also includes identifying a non-fungible token associated with the user. The non-fungible token associated with the user includes one or more stored physical characteristic of the user. The method further includes comparing the one or more potential physical characteristics of the authentication request with the one or more stored physical characteristics of the user. The method still further includes generating an access determination for the authentication request based on the comparison of the one or more potential physical characteristics of the authentication request with the one or more stored physical characteristics of the user.
