Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If derivative work data is stored in traditional digital spaces, then storage and access are simple, but it becomes difficult to identify and track derivative works back to original sources
Solution Approach 1:
The patent introduces a blockchain as an intermediary ledger that stores cryptographic hashes of original works and their derivative works. This intermediary structure enables reliable traceability by creating an immutable chain of derivatives without requiring direct access to the actual creative works, thus solving the traceability problem while maintaining manageable complexity through the use of hash-based references.
Solution Approach 2:
The patent creates cryptographic copies (hashes) of original works and stores them on the blockchain. These hash copies serve as unique identifiers that can be verified without storing the actual original works, enabling traceability of derivative works while keeping the system complexity manageable through efficient data representation.
2Reliability
If verification processes are made rigorous to ensure derivative work authenticity, then reliability improves, but processing time and computational resources increase
Solution Approach 1:
The patent extracts the verification function into a separate, efficient process that compares cryptographic hashes rather than analyzing the actual derivative works. This extraction allows for rapid verification by checking whether the hash of a derivative work matches a recorded hash on the blockchain, significantly reducing processing time while maintaining high verification accuracy.
Solution Approach 2:
The patent changes the verification parameter from analyzing the actual content of derivative works to comparing cryptographic hashes. This parameter transformation enables fast, reliable verification by working with fixed-length hash values instead of variable-sized creative works, thus reducing computational resources and processing time while maintaining verification rigor.
