Entity-Sovereign Data Wallets Using Distributed Ledger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of control over personal data shared between entities due to privacy and security concerns leads to unreliable and siloed data sets, causing inefficiencies and security breaches.
Innovation Solution
A distributed ledger-based system that allows users to manage permissions for data access, using claims instead of specific values, ensuring data sovereignty and secure sharing across entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users share personal data with entities, then entities can provide tailored services and applications, but users lose control over their data and face privacy and security risks
Solution Approach 1:
The patent segments data access control into granular permission units that can be individually managed. Users can divide their data rights into specific access permissions for different entities, time periods, and data types, allowing selective sharing without complete data exposure. This segmentation enables tailored service provision while maintaining user control and security.
Solution Approach 2:
The patent introduces a distributed ledger system as an intermediary between users and entities. This mediator maintains a transparent record of all data access permissions and transactions, enabling verified data sharing without direct trust relationships. The intermediary layer ensures security and privacy while facilitating versatile data access for personalized services.
2Reliability
If entities maintain separate user profiles with siloed data, then each entity can control its own data quality, but data remains fragmented and redundant across systems
Solution Approach 1:
The patent creates a universal permission management system that works across multiple entities simultaneously. A single user profile with centralized permission controls can interact with multiple entities through the distributed ledger, eliminating the need for separate user profiles at each entity. This multi-functional approach maintains data quality control while preventing fragmentation and redundancy.
Solution Approach 2:
The patent merges data access control mechanisms into a unified system based on distributed ledger technology. Instead of maintaining separate user profiles at each entity, the system combines all permission management into a single user-controlled interface that coordinates access across multiple entities, eliminating data silos while preserving quality control.
3Measurement precision
If entities request complete user information for accurate service delivery, then service quality improves, but user privacy and security concerns increase
Solution Approach 1:
The patent applies local quality by allowing different levels of information disclosure to different entities based on specific permission grants. Users can provide complete information to some entities while providing limited or no information to others, enabling each entity to receive precisely the accuracy it needs without exposing users to unnecessary privacy risks across all systems.
Solution Approach 2:
The patent enables partial action by allowing users to share only the specific data points needed for particular services rather than complete user profiles. Users can grant permission for individual data elements or subsets of data, providing just enough information for accurate service delivery while minimizing privacy and security exposure.
4Reliability
If users provide accurate personal information, then entities can make reliable determinations, but users expose themselves to security breaches and unauthorized access
Solution Approach 1:
The patent implements preliminary action by establishing permission controls and access permissions before any data is shared. Users pre-configure what information can be accessed, by whom, and under what conditions. This preliminary setup ensures that only authorized entities can access accurate user information, maintaining determination accuracy while preventing unauthorized access and security breaches.
Data Source
AI summary
In various embodiments, a request is received for a claim that is responsive to an interrogatory, where the interrogatory uses values of items of interest regarding a subject user to produce the claim. Based on the request, it is determined that one or more permissions, included in one or more digitally signed transactions of one or more transaction blocks on one or more copies of a blockchain maintained at least in part by nodes of a distributed ledger system, represents the subject user granting a receiving entity with a right to receive claims that are responsive to interrogatories that use the values to produce the claims. Based on the determining, the receiving entity is granted access to the claim.
