Cryptographic Token Data Control for Selective Blockchain Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users lose control over their data once it is transferred to third parties, leading to unauthorized access and propagation, which discourages data sharing without consent.
Innovation Solution
A cryptographic token system using blockchain operations and asymmetrical encryption allows users to securely share and control data access, enabling entities to analyze user characteristics and provide personalized services while maintaining user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is transferred to third parties, then data sharing and service provision are enabled, but user control and exclusivity over the data are lost
Solution Approach 1:
The patent segments data access control into granular permission levels (full access, read-only, analyze-only, etc.), allowing users to divide and control different aspects of data access separately. This enables selective sharing while maintaining overall control through the cryptographic token system.
Solution Approach 2:
The cryptographic token acts as an intermediary between the user and third-party entities. The token encapsulates user data and control permissions, mediating the trust relationship. Users transfer control of the token rather than raw data, enabling third parties to access data only through the token's controlled interfaces.
2Ease of operation
If users relinquish control of their data, then access can be provided to entities, but users lose ability to disable access or modify permissions
Solution Approach 1:
The cryptographic token system enables dynamic permission modification. Users can update the token's access control list (ACL) to add, remove, or modify permissions for different entities at any time. The token's state is mutable, allowing real-time adaptation of access rights without requiring data re-transfer.
Solution Approach 2:
The system provides feedback mechanisms where users receive notifications when entities access their data through the token, and the token itself encodes the current permission state. This feedback loop enables users to monitor and adjust permissions based on ongoing needs.
3Productivity
If data is shared with entities, then services can be provided to users, but unauthorized propagation and use of data occurs
Solution Approach 1:
The cryptographic token embeds access control permissions directly into the data encapsulation structure before sharing. This preliminary security measure prevents unauthorized propagation by design - entities without valid token permissions cannot access or re-transmit the data, regardless of their position in the data flow.
Solution Approach 2:
The patent replaces traditional mechanical access control (firewalls, gatekeepers, centralized authentication servers) with cryptographic mechanisms. The token's cryptographic structure inherently enforces access controls, eliminating the need for additional security infrastructure between data producer and consumer.
4Measurement precision
If users provide data to entities, then data can be analyzed for user characteristics, but users lose control over how data is used
Solution Approach 1:
The patent applies different quality levels of data access to different entities based on their role and trust level. The token's access control list can grant specific entities permission to analyze data for characteristic determination while preventing others from accessing the same data, enabling differentiated data quality control.
Data Source
AI summary
The invention relates to generating cryptographic tokens based on received records. The system may receive a blockchain operation request comprising a plurality of records, encrypt a plurality of records into an encrypted payload, generate a cryptographic token based on the encrypted payload, and cause the cryptographic token to be committed to a blockchain.
