Solution Overview
Problem
There is a need for a reliable method to verify the authenticity of recordings, particularly in legal proceedings, to ensure that electronic files accurately represent the events recorded without tampering, as allegations of alteration can have serious consequences.
Innovation Solution
A method involving creating a cryptographic hash of the recording, generating certification requests based on this hash and associated data, and submitting them to a blockchain for verification, providing a confirmation of the recording's integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional storage methods are used for electronic recording files, then storage simplicity is maintained, but the reliability and tamper-evidence of the recording cannot be guaranteed
Solution Approach 1:
The patent applies preliminary action by generating the cryptographic hash of the recording and submitting it to the blockchain immediately after recording, before any potential tampering can occur. This creates a proactive verification mechanism where the integrity is established in advance, allowing later verification without complex ongoing monitoring systems.
Solution Approach 2:
The patent introduces a blockchain intermediary that mediates between the recording system and verification processes. The blockchain serves as a trusted third-party ledger that stores hash values and certification requests, enabling reliable verification without requiring direct trust between recording custodians and verifying parties, thus simplifying the overall system architecture.
2Reliability
If immediate verification is performed after recording creation, then the time window for potential tampering is minimized, but the processing time and system response requirements increase
Solution Approach 1:
The patent segments the verification process into distinct components: recording creation, hash generation, blockchain submission, and later verification. This segmentation allows the time-consuming cryptographic operations to be performed in discrete steps rather than requiring continuous processing, reducing the perceived delay while maintaining immediate tamper-evidence capability.
Solution Approach 2:
The patent uses cryptographic hashing to create a compact copy (hash value) of the recording that can be stored and verified independently. This copying mechanism allows the actual recording to remain unchanged while its integrity is verified through the hash comparison, enabling rapid verification without reprocessing the entire recording file.
3Reliability
If cryptographic hash functions and blockchain technology are implemented, then the tamper-evidence and verification capability is significantly improved, but the computational resources and system complexity increase
Solution Approach 1:
The patent extracts only the essential verification element (cryptographic hash) from the complete recording and submits only this condensed representation to the blockchain. This extraction approach minimizes computational energy consumption by avoiding the need to process, store, or transmit the entire recording file, while still providing comprehensive integrity verification.
Solution Approach 2:
The patent transforms the recording into a different parameter representation (hash value) that is computationally efficient to store and compare. This parameter change from raw recording data to cryptographic hash enables rapid verification with minimal energy consumption, as hash comparison is far less computationally intensive than analyzing the original recording content.
4Loss of information
If a chain of custody system is established using blockchain, then the transparency and accountability of recording management is improved, but the system complexity and implementation difficulty increase
Solution Approach 1:
The patent implements a multi-functional blockchain system that simultaneously provides chain of custody tracking, integrity verification, and authentication capabilities through a single integrated platform. This universal approach consolidates multiple verification functions into one system, reducing overall complexity compared to implementing separate systems for each function.
Solution Approach 2:
The patent incorporates feedback mechanisms where the blockchain system provides verification status and certification information back to the recording custodians and verifying parties. This automated feedback loop reduces manual tracking and documentation requirements, simplifying the chain of custody management while maintaining comprehensive information tracking.
