Trail Collection System Verification via Identification Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing a trail of a device rely on assumptions that may lead to incorrect trail registration due to potential mismatches between identification information and trail information, resulting in authenticity issues.
Innovation Solution
A trail collection system comprising a trail acquisition apparatus and a trail provision apparatus, where the trail acquisition apparatus reads identification information from a symbol attached to a managed object and transmits a request, and the trail provision apparatus determines if the information matches stored identification, transmitting trail information or its hash value when a match is found.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system assumes the server receives identification data transmitted from the device, then the trail registration process is simplified, but the authenticity and accuracy of the trail information cannot be guaranteed due to potential mismatches between identification information and trail information
Solution Approach 1:
The system performs preliminary actions by attaching identification information to the managed object before trail registration. The trail acquisition apparatus reads this pre-attached identification information and transmits it to the trail provision apparatus, ensuring the correct association between identification and trail information before the actual registration occurs.
Solution Approach 2:
The trail provision apparatus compares the received identification information with stored identification information and provides feedback by determining whether they match. This feedback mechanism ensures that only correctly associated trail information is registered, preventing authenticity issues while maintaining a relatively simple registration process.
2Reliability
If the system transmits and stores complete trail information, then the trail data is fully available for verification, but the data transmission and storage requirements increase significantly
Solution Approach 1:
The system extracts only the essential identification information from the complete trail data and transmits it for verification purposes. The trail provision apparatus stores and compares this extracted identification information, allowing verification of trail authenticity without requiring transmission of the entire trail data set.
Solution Approach 2:
The system uses identification information as a copy or key that represents the complete trail data. By transmitting and verifying this representative copy rather than the full trail information, the system enables verification while minimizing data transmission and storage requirements.

AI summary
A trail management system (2000) includes a trail acquisition apparatus (2100) and a trail provision apparatus (2200). The trail acquisition apparatus (2100) reads first identification information from a symbol (20) attached to a managed object (10), and transmits a request (40) including the first identification information. The trail provision apparatus (2200) receives the request (40), and determines whether the first identification information included in the request (40) matches second identification information stored in a storage unit (2280) of the trail provision apparatus (2200). In a case where the information matches, the trail provision apparatus (2200) transmits a response (50) including trail information or a hash value of the trail information. The trail acquisition apparatus (2100) receives the response (50).
