Digital Content Authentication via Blockchain Fingerprinting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for authenticating and writing digital content items to blockchain are limited in their ability to guarantee authenticity, as they typically only consider a few characteristics such as color and identification codes, failing to ensure the integrity of the digital content item across its composition and display.
Innovation Solution
A system that extracts and writes digital content item data using modules for pixel value and coordinate extraction, combined with image processing and data generation, to authenticate and securely store digital content items on a blockchain network, enabling broader data collection and consensus-based authenticity guarantees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If limited characteristics (color, ID code, object names) are encoded in blockchain, then the system is simple to operate, but the authenticity guarantee is insufficient for complete digital content item verification
Solution Approach 1:
The digital content item is segmented into multiple characteristic components (color, identification code, object names, pixel values, coordinates) that are extracted and encoded separately, then collectively stored on the blockchain to provide comprehensive authenticity verification
Solution Approach 2:
The system performs preliminary extraction of digital content item characteristics before blockchain storage, creating a reference fingerprint that enables future authentication comparisons without requiring complex processing during verification
2Reliability
If comprehensive digital content item data is extracted and stored on blockchain, then authenticity verification is improved, but the data processing time increases
Solution Approach 1:
Only essential characteristic data (pixel values, coordinates, identifying features) is extracted from the complete digital content item for blockchain storage, rather than storing the entire file, thereby maintaining verification reliability while reducing processing time and storage requirements
Solution Approach 2:
The system extracts a partial representation (fingerprint) of the digital content item that contains sufficient information for authentication purposes, avoiding the need to process and store complete high-resolution data
