Validating Sensor Data Authenticity via Blockchain Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in confirming the authenticity of data files from capture devices, determining true representations of changes in modified files, and validating the authenticity of various versions of files, particularly in verifying whether files contain true copies of as-recorded data or represent verifiable variations of tracked portions.
Innovation Solution
A computer system processes capture device output to create a validatable master file with blockchain data, metadata, and signed hashes, allowing for the validation of original media data and tracking changes through cryptographic processing, generating reference files with incremental blockchain data, and verifying the authenticity of modified and distributable files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic processing is applied to validate media data authenticity, then reliability of data verification is improved, but device complexity increases due to blockchain data structures and cryptographic operations
Solution Approach 1:
The media data is divided into tracked portions, and cryptographic processing is applied selectively to these specific portions rather than the entire data set. The blockchain structure segments verification into discrete blocks that can be independently validated, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
A blockchain data structure acts as an intermediary between the original media data and verification processes. This intermediary layer provides a standardized, immutable record of data integrity that simplifies verification operations while enhancing reliability through cryptographic chaining.
2Measurement precision
If tracked portions of media data are identified and validated, then measurement precision of data integrity is improved, but loss of time increases due to cryptographic hashing and validation operations
Solution Approach 1:
Cryptographic hashing and blockchain recording are performed on tracked portions of media data at the time of data capture or initial processing. This preliminary action creates immutable verification records in advance, enabling rapid validation later without time-consuming real-time cryptographic operations.
Solution Approach 2:
Only the essential cryptographic elements (hash values, blockchain references) are extracted and stored for verification purposes, while the full media data remains separate. This extraction allows precise integrity verification without requiring re-processing of the entire original data set.
3Reliability
If blockchain data structures are implemented to track file modifications, then reliability of modification tracking is improved, but device complexity increases due to incremental blockchain management
Solution Approach 1:
The blockchain structure is designed to dynamically accommodate modifications through incremental block addition. Each modification creates a new block that references previous blocks, allowing the system to adapt to changing data states while maintaining a reliable audit trail without requiring complete restructuring.
Solution Approach 2:
The blockchain data structure and tracking mechanisms are established in advance with predefined rules for modification recording. This preliminary setup enables automated, consistent tracking of all future modifications without requiring complex real-time decision-making or manual configuration.

AI summary
A computer identifies capture device output that represents an aspect of a recorded event. The computer cryptographically processes the tracked portions of capture device output to produce a validatable master file which includes master file media data tracked portion from the capture device output, master tracked portion metadata of said master file media data tracked portion, and master file blockchain data. The master file blockchain data includes a master file block history portion, a master file signature key portion, and a signed hash of said master file media data tracked portion. The computer also modifies the master file media data tracked portion to produce a reference file media data tracked portion. reference files and distributable files. The computer verifies the authenticity of each of these files.
