Decentralized User Authentication via Reputation-Based Quorum Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network authentication methods are inefficient and insecure, requiring human intervention, prone to errors, and vulnerable to identity theft, especially when verifying new users remotely.
Innovation Solution
A decentralized authentication system that uses a server to query a database of existing users with verified reputation scores to verify new user attributes through a graphical user interface, ensuring authentication only when a quorum of users confirms the new user's identity, thereby reducing human error and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods requiring human intervention and physical presence are used, then authentication reliability is improved, but authentication time and operational complexity increase
Solution Approach 1:
The system enables new users to authenticate themselves through self-service by providing personal information that is automatically verified against existing user data and reputation scores, eliminating the need for administrators to manually verify identities in person
Solution Approach 2:
The system introduces an intermediary verification mechanism where existing users with high reputation scores act as indirect validators of new user identities through their associated personal information, replacing direct human intervention with a automated trust-based verification system
2Productivity
If personal questions and identifying information are used for authentication, then authentication speed is improved, but security against identity theft deteriorates
Solution Approach 1:
The system implements feedback mechanisms where existing users' reputation scores and verification histories continuously inform the authentication process, allowing the system to adaptively assess trustworthiness and detect potential identity theft attempts based on community feedback
Solution Approach 2:
The system performs preliminary verification by cross-checking new user personal information against existing user data and reputation scores before completing authentication, preventing identity theft before it can occur rather than detecting it after the fact
3Reliability
If decentralized verification with multiple existing users is implemented, then authentication security is improved, but system complexity increases
Solution Approach 1:
The system segments the authentication process into distinct components: personal information collection, database verification against existing users, reputation score assessment, and final authentication decision, making the complex decentralized verification process manageable and scalable

AI summary
Embodiments disclosed herein may relate to systems and methods for secure authentication that enable a user to set up an account or log in an existing account upon an existing user vouching for the user. Embodiments disclosed herein relate to verifying one or more attributes of the user by transmitting multiple decentralized verification notifications to multiple existing users. Upon receiving a verification quorum, a request may be authenticated.
