Distributed Ledger Authentication for Identity Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity management systems are centralized, making them vulnerable to single points of failure, malicious attacks, and data manipulation, and they struggle with secure and efficient exchange of restricted information due to complexity and cost issues, especially when dealing with user-based licenses and distributed data access.
Innovation Solution
A distributed secure ledger system using public or private digital ledgers for authentication, which generates obfuscated unique identities and updates the ledger securely, enabling secure user access to licensed digital media and software through a verification method that validates credentials and updates the ledger, leveraging blockchain technology for integrity and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized identity management systems are used, then identity verification can be established, but the system becomes vulnerable to single points of failure, malicious attacks, and data manipulation
Solution Approach 1:
The patent segments the centralized identity management system into a distributed network of nodes, where identity data is divided and stored across multiple participants rather than in a single central repository. This segmentation eliminates the single point of failure by distributing trust and data across the network, making the system resistant to attacks on individual nodes.
Solution Approach 2:
The patent transitions from a traditional centralized hierarchical model to a distributed network model, adding the dimension of decentralization. This dimensional change fundamentally alters the system architecture from top-down control to peer-to-peer verification, enhancing security while reducing centralization vulnerabilities.
2Reliability
If encryption and certificates are used to protect centralized systems, then security is improved, but complexity and costs increase
Solution Approach 1:
The patent implements self-service security mechanisms where network participants independently verify identities through cryptographic proofs and consensus algorithms without requiring complex centralized security infrastructure. Each node autonomously validates transactions and maintains security, eliminating the need for expensive centralized security operations centers and complex certificate management systems.
3Adaptability or versatility
If user-based licenses are granted allowing access from multiple devices, then user flexibility is improved, but secure access control becomes more difficult
Solution Approach 1:
The patent introduces digital tokens and cryptographic intermediaries that enable flexible user-based licensing while maintaining secure access control. These digital intermediaries act as verifiable proofs of authorization that can be safely shared across multiple devices without compromising security, allowing users to access licensed content from any device while the system maintains precise control over what each user can access.
