Cryptographic Data Tokens for User-Controlled Characteristic 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
Generate cryptographic tokens that encapsulate user data using asymmetric encryption, allowing users to control access and sharing through blockchain operations, enabling entities to analyze data with permission and reward users for their characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users transfer data to third parties, then data sharing and service provision are enabled, but users lose control over their data and it may be propagated to unauthorized entities
Solution Approach 1:
The patent segments user data into discrete cryptographic tokens that can be individually controlled. Each token represents a specific data element or access permission, allowing users to grant selective access to third parties without transferring complete data control. This segmentation enables granular data sharing while maintaining user oversight through the ability to manage individual tokens.
Solution Approach 2:
The patent introduces a blockchain-based intermediary system that mediates between users and third parties. The blockchain network acts as a trusted mediator that verifies user consent, manages cryptographic token distribution, and enforces access permissions. This intermediary enables data sharing while preserving user control through decentralized verification mechanisms.
2Productivity
If users provide data to entities, then personalized services and user characteristic analysis are enabled, but data may be accessed by undesirable entities without consent
Solution Approach 1:
The patent implements preliminary action by requiring users to pre-authorize data access through cryptographic token issuance before any third party can access their data. The system establishes access permissions in advance through blockchain-based consent mechanisms, ensuring that only authorized entities can retrieve user data. This preliminary authorization prevents unauthorized access while enabling efficient service provision.
Solution Approach 2:
The patent changes the parameter of data access from traditional permission models to cryptographic token-based access control. By transforming data representation into tokenized form on the blockchain, the system enables precise control over who can access what data. This parameter change allows entities to efficiently access authorized data while the blockchain's immutable ledger prevents unauthorized access propagation.
3Ease of operation
If conventional data storage is used, then data access is simple, but users cannot revoke or modify permissions after data transfer
Solution Approach 1:
The patent implements dynamic permission control through blockchain-based cryptographic tokens that can be modified or revoked by users at any time. Unlike static conventional storage systems, the blockchain ledger allows users to update their consent status, revoke tokens, or modify access permissions dynamically. This dynamic capability maintains operational simplicity while providing flexible permission management throughout the data lifecycle.
Data Source
AI summary
The invention relates to generating cryptographic tokens based on characteristic determination. The system may generate and transmit a request for encrypted records from a blockchain node, receive the encrypted records from the blockchain node, decrypt the encrypted records into payload identifiers, retrieve sets of item identifiers based on the payload identifiers, determine characteristics associated with the sets of items, and generate a new cryptographic token that indicates the characteristics.
