Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data collection methods in IoT systems, such as edge computing, lack mechanisms to ensure data credibility and prevent tampering during the collection process, making it difficult for data users to verify the integrity of the data.
Innovation Solution
A data managing apparatus and method that utilizes public and private keys to generate and verify hash values from collection history information, ensuring that only authorized processing occurs by maintaining the data history when the hash values match, thus preventing tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data collection is performed using edge computing methods, then data collection efficiency is improved, but data credibility and integrity cannot be ensured
Solution Approach 1:
The patent applies preliminary action by generating hash values of collection history information at the edge device before data transmission, and pre-establishing cryptographic key pairs for authentication. This allows integrity verification to be prepared in advance, ensuring data credibility is maintained from the moment of collection without compromising efficiency.
Solution Approach 2:
The patent implements feedback mechanisms where the central apparatus verifies hash values against collected data and sends authentication results back to edge devices. This closed-loop verification ensures that only credible data is accepted, while maintaining efficient data collection through automated validation.
2Reliability
If data tampering prevention mechanisms are implemented, then data integrity is improved, but system complexity increases
Solution Approach 1:
The patent uses hash values as intermediary elements that represent complex data integrity verification processes. Instead of directly implementing complex verification logic at every node, the system uses hash values as mediators to simplify the verification process, reducing system complexity while maintaining data integrity.
Solution Approach 2:
The patent replaces mechanical data verification methods with cryptographic hash functions and digital signature mechanisms. This substitution eliminates the need for complex manual verification processes while providing robust data integrity protection, thereby reducing operational complexity.
3Reliability
If hash value verification is performed on all collected data, then data authenticity is improved, but processing time increases
Solution Approach 1:
The patent applies partial action by performing hash verification selectively on critical data points or sampling mechanisms rather than every single data point. This approach maintains data authenticity for essential information while reducing overall processing time through targeted verification.
Solution Approach 2:
By pre-generating hash values at the edge device before transmission, the system eliminates the need for time-consuming hash calculations at the central apparatus. This preliminary computation significantly reduces processing time while maintaining thorough verification of data authenticity.
