Blockchain Ledger Keys for Scalable Anonymized Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data exchange methods among enterprises result in a highly constrained hub and spoke model with significant operational overhead and lack scalability, as enterprises struggle to create holistic consumer profiles due to limited domain-specific information.
Innovation Solution
A method and system for managing anonymized data across computing devices in a blockchain network, involving generating a blockchain ledger based on user datasets, constructing it with customization settings and criteria, and using unique ledger keys for secure data exchange between entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If enterprises use traditional clean room cloud solutions to exchange consumer information, then holistic consumer profiling is enabled, but operational overhead increases and scalability decreases
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that acts as a neutral mediator between enterprises. The blockchain ledger stores anonymized consumer data with encrypted identifiers, allowing enterprises to query and match consumers across domains without direct access to each other's raw data. This intermediary mechanism enables holistic consumer profiling while eliminating the need for complex operational coordination that traditional clean room solutions require.
2Loss of information
If enterprises use traditional clean room cloud solutions to exchange consumer information, then holistic consumer profiling is enabled, but scalability is reduced
Solution Approach 1:
The blockchain ledger implements a universal data structure that can accommodate multiple enterprises and consumer datasets simultaneously. The system uses standardized anonymized identifiers and encryption schemes that work across different enterprise domains, allowing new participants to join the network without requiring custom integration for each enterprise. This universal approach enables the system to scale from a few participating enterprises to many while maintaining consistent consumer profiling capabilities.
3Reliability
If consumer information is exchanged among enterprises through restricted environments, then data privacy is maintained, but system complexity and operational overhead increase
Solution Approach 1:
The patent extracts the privacy-protection mechanism from complex operational environments and embeds it directly into the blockchain data structure. Consumer data is stored in an anonymized format with encrypted identifiers on the blockchain itself, rather than requiring separate restricted access environments. The cryptographic hashing and encryption operations are performed once during data ingestion, and the blockchain's inherent immutability and distributed consensus provide ongoing privacy protection without requiring continuous operational oversight.
