Blockchain Identity Timeline for Secure Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively track and validate changing identities of users over time, leading to authentication challenges and security vulnerabilities.
Innovation Solution
A blockchain-based system that records and stores user identifications over time, generating a timeline of changes and using this data to create factually-based challenge questions for authentication, allowing tiered access to secure locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication systems are used, then user identification can be updated, but the system cannot track and validate changing identities over time
Solution Approach 1:
The system performs preliminary actions by capturing and storing user identification data at multiple points in time before authentication is needed. The blockchain ledger pre-records identity morphs including name changes, signature changes, and physical attribute changes, so that when authentication occurs, the complete identity history is already available for validation and challenge question generation.
2Adaptability or versatility
If user identification is updated over time, then user information remains current, but the system cannot generate accurate authentication questions
Solution Approach 1:
The system uses feedback from the blockchain ledger containing historical identification data to generate accurate authentication questions. By analyzing the recorded identity morphs over time, the system receives feedback about what information has changed and remains stable, enabling it to create challenge questions that are both adaptive to current identity and grounded in verified historical facts about the user.
3Reliability
If third party authentication is required, then security is enhanced, but additional authentication requirements increase complexity
Solution Approach 1:
The blockchain ledger serves as an intermediary that bridges traditional authentication systems and modern identity verification needs. Rather than requiring multiple third-party authentication systems to directly communicate and coordinate, the blockchain ledger acts as a neutral mediator that stores and validates identity information, allowing participating systems to independently verify user identity without direct complex interactions with each other.
Data Source
AI summary
Embodiments of the invention are directed to a system, method, or computer program product for generating and using a block chain distributed network for tracking and validating a user identification morphing over time. The block chain database comprises a distributed ledger that is updated with real-time identification information including an initial identification of the user. Subsequent identifications are stored and changes or morphs in identification, such as signatures, physical attributes, or locations of the user are identified. User facts are correlated with the identifications to build a timeline for the user. Subsequently, the system generates authentication questions based off of the timeline generated. The authentication questions allow for authentication of a user into a third party system.
