Trusted Assertion Service for Data Provenance Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data marketplaces lack robust mechanisms for verifying the integrity, provenance, and chain-of-handling of data, making it difficult for data consumers to trust the authenticity and origin of the data they access.
Innovation Solution
A trusted data management architecture that securely records information about data provenance and chain-of-handling using a trusted assertion service, allowing data consumers to authenticate and verify the origin and processing history of data through cryptographically signed assertions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data marketplaces are used, then data access and distribution are simplified, but the ability to verify data integrity, provenance, and chain-of-handling is insufficient
Solution Approach 1:
The patent introduces a trusted assertion service as an intermediary between data providers and data consumers. This service receives cryptographically signed assertions from data providers about data provenance and integrity, then provides these verified assertions to data consumers. This mediator resolves the contradiction by enabling reliable data verification without requiring complex verification mechanisms to be implemented directly in the data marketplace infrastructure.
Solution Approach 2:
The patent replaces manual or conventional verification mechanisms with cryptographic verification. Instead of relying on trust-based or administrative verification processes, the system uses cryptographic signatures and blockchain technology to automatically verify data provenance and integrity. This substitution enables robust verification while maintaining system simplicity, as the cryptographic mechanisms handle the complexity automatically.
2Reliability
If data provenance and chain-of-handling information is recorded and verified, then data authenticity is enhanced, but system complexity and processing overhead increase
Solution Approach 1:
The patent segments the verification functionality into a separate trusted assertion service, distinct from the core data marketplace operations. Data providers submit assertions to this specialized service, which then makes verification information available to consumers. This segmentation allows comprehensive provenance tracking without complicating the overall marketplace architecture, as the verification subsystem operates independently.
Solution Approach 2:
The patent uses cryptographic copying of provenance information through digital signatures. Instead of storing and managing complex verification records throughout the system, the original provenance data is signed cryptographically, and these signature copies are distributed and verified wherever needed. This copying approach maintains data authenticity while avoiding the need for complex centralized verification storage and management.
3Measurement precision
If cryptographic verification mechanisms are implemented, then data integrity verification is strengthened, but processing time and computational resources increase
Solution Approach 1:
The patent performs cryptographic signing of data provenance information in advance, when data is first provided to the marketplace. The trusted assertion service receives and validates these pre-signed assertions, making verification information ready before data consumers need it. This preliminary action eliminates the need for time-consuming cryptographic operations at the point of data consumption, as verification can be performed using already-computed signatures.
Solution Approach 2:
The patent extracts the computationally intensive cryptographic verification operations from the data consumption process and consolidates them in the trusted assertion service. Data consumers only need to request and receive pre-verified assertions, while the heavy lifting of cryptographic validation is performed once by the assertion service during assertion submission. This extraction reduces verification time for end users while maintaining security.
