Blockchain User Data Access Control for Personalization Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in controlling their personal information stored across multiple third-party databases, leading to repetitive data sharing, unauthorized replication, and difficult data deletion, with limited control over how their data is used and managed.
Innovation Solution
A computing system utilizing blockchain technology to manage user data and personalization models, allowing users to control access and sharing of their data through blockchain-based permissions, enabling secure data management and user-driven decisions on data usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If user data is stored in multiple third-party databases, then data availability and accessibility are improved, but user control and data security deteriorate
Solution Approach 1:
The patent introduces a blockchain-based data management system as an intermediary between users and third-party services. Users maintain centralized control of their data on the blockchain, while third parties access data through controlled interfaces. This intermediary layer preserves data availability for services while ensuring user control and security through blockchain's immutable ledger and access control mechanisms.
2Adaptability or versatility
If third parties aggregate and store user data, then service functionality and personalization are improved, but data security and user privacy deteriorate
Solution Approach 1:
The patent extracts user data from third-party databases and relocates it to a user-controlled blockchain storage system. Users can selectively share specific data attributes with third parties through controlled interfaces rather than having third parties store comprehensive data copies. This extraction eliminates the harmful factor of unauthorized data aggregation while preserving service functionality through controlled data access.
Solution Approach 2:
The system implements feedback mechanisms where users are notified of data access requests and can control whether to grant access. This feedback loop ensures users maintain awareness and control over their data, preventing unauthorized aggregation while allowing necessary data sharing for service functionality to operate.
3Loss of information
If users provide data to multiple third parties, then data completeness for services is improved, but ease of data deletion and control deteriorates
Solution Approach 1:
The patent merges all user data into a single centralized location on the blockchain rather than dispersing it across multiple third-party databases. This consolidation maintains data completeness for services through controlled access interfaces while dramatically simplifying data deletion, as users can remove data from one centralized source rather than navigating through multiple third-party systems.
4Productivity
If third parties replicate and alter user data, then data utilization and service optimization are improved, but data integrity and user trust deteriorate
Solution Approach 1:
Instead of third parties creating and storing copies of user data, the patent uses blockchain's distributed ledger technology to provide verified copies of data to authorized services. Each data access is recorded on the blockchain, creating an immutable audit trail that ensures data integrity while allowing efficient data utilization across multiple services simultaneously.
Data Source
AI summary
Systems and methods for the authorization of access to user data can include the use of one or more blockchains to store the user data and/or an authorization list. The systems and methods can receive and/or obtain an access request. The access request can be processed to determine if the requestor has authorization. The processing can include interactions with a user computing system and/or an authorization list. An authorized access can be provided such that the requestor can read the user data stored on the blockchain with limited copy and/or overwrite access.
