Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in managing user identities and securing data, with centralized approaches incurring costs and privacy concerns, and there is a need for user-controlled access control in peer-to-peer networking.
Innovation Solution
A decentralized Internet Protocol-based communication protocol (@protocol) enables user-controlled access control through decentralized resource directories and a namespace directory, allowing users to manage their personal information and data without relying on third-party services, with secure key/value persistence and permission-based access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized systems are used to manage user identities and data, then system coordination and resource management are simplified, but privacy concerns increase and user control is reduced
Solution Approach 1:
The system segments user data and identity management into decentralized resource directories distributed across multiple peer nodes. Each user has their own resource directory that stores authentication credentials and data, eliminating the need for a single centralized authority while maintaining systematic coordination through standardized protocols.
Solution Approach 2:
The patent introduces an authentication challenge mechanism as an intermediary between users and resource directories. The challenge-value system acts as a mediator that enables secure authentication and access control without requiring users to directly trust centralized authorities, thus protecting privacy while enabling system coordination.
2Reliability
If decentralized resource directories are implemented, then user control and privacy are enhanced, but system complexity increases
Solution Approach 1:
The patent implements a universal authentication protocol that works across different decentralized resource directories and peer nodes. The challenge-response mechanism and standardized connection procedures provide multi-functional capabilities that simplify interactions despite the decentralized architecture, reducing the perceived complexity for users and developers.
Solution Approach 2:
The system changes the authentication parameter from traditional username/password to challenge-value pairs. This parameter transformation enables simplified authentication flows in decentralized environments, where dynamic challenge values replace static credentials, making the system both more secure and easier to implement across distributed nodes.
3Reliability
If authentication challenges require storing values in decentralized directories, then security is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing connections to decentralized resource directories and pre-generating authentication challenges. The challenge values are stored in advance in the user's resource directory, allowing rapid authentication when needed without time-consuming real-time generation or verification processes.
Solution Approach 2:
The authentication mechanism uses copying of challenge-values between the resource directory and the authenticating peer. Instead of complex real-time verification computations, the system copies and compares challenge values, significantly reducing authentication time while maintaining security through the decentralized storage and verification process.

AI summary
The present disclosure involves systems, software, and computer implemented methods for user-controlled access control for user information. One example method includes sending an authentication request to authenticate as a requesting entity to a first decentralized resource directory of a providing entity. An authentication challenge is received, via the connection, from the providing entity, and in response to the authentication request, to store an authentication challenge value for an authentication challenge key in a second decentralized resource directory of the requesting entity. The authentication challenge value for the authentication challenge key is stored in the second decentralized resource directory. An authentication challenge response is sent to the providing entity requesting the providing entity to verify the authentication challenge. An indication is received from the providing entity indicating that the requesting entity is authenticated to the first decentralized resource directory as the requesting entity.
