Network Interaction Method for Secure File Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the import-export trade industry, the lack of effective regulation for uploading materials to inspection agencies leads to concerns of falsification, and existing methods compromise the security of uploaded information as it is stored on inspectors' terminal devices during verification.
Innovation Solution
A network interaction method involving a client, server, and electronic device where an identification code is generated and used to associate files uploaded by users with their corresponding information, ensuring that only file information is sent to the inspector's client, maintaining the security of uploaded materials by not storing the files on the client device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inspector uploads the user's material using the inspector's terminal device, then the verification process can be completed, but the material security is compromised because the material is stored on the inspector's device
Solution Approach 1:
The patent divides the material into two separate parts: the original file and the verification code. The original file remains on the user's device and is never transferred to the inspector's device. Only the verification code (a non-sensitive identifier) is transmitted to enable verification. This segmentation allows the inspector to verify the material's authenticity without obtaining access to the actual confidential content, thus resolving the contradiction between verification capability and material security.
Solution Approach 2:
The verification code acts as an intermediary element between the original material and the verification process. Instead of directly handling or storing the confidential material, the inspector's system uses this intermediate verification code to confirm the material's legitimacy. The verification code serves as a mediator that enables the verification function while maintaining the security boundary that prevents the inspector's device from accessing or storing the actual material.
2Measurement precision
If the inspector's terminal device stores the uploaded material during verification, then the verification can be performed, but the risk of information leakage and falsification increases
Solution Approach 1:
The material is segmented into the original file (kept securely on the user's device) and a verification code (transmitted to the inspector's device). This segmentation enables the inspector to perform verification operations with the code while the original confidential material never leaves the user's secure environment, thereby eliminating the information leakage risk while maintaining verification accuracy.
Solution Approach 2:
Instead of copying or transferring the original material to the inspector's device, the system creates and uses a verification code that represents or references the original material. This verification code is a simplified representation that contains enough information to verify authenticity but lacks the actual confidential content. The inspector operates on this copy/representation rather than the original, ensuring verification can proceed without exposing the sensitive material.
3Reliability
If the user uploads material directly through their own device, then the material security is maintained, but there is no effective regulation to prevent falsification
Solution Approach 1:
The system implements a feedback mechanism where the inspector's verification result (confirming the validity of the verification code) is transmitted back to the user's device and/or the server. This feedback loop provides regulatory oversight: the user generates a verification code from their material, the inspector verifies it, and the verification result is fed back to confirm authenticity. This feedback mechanism prevents falsification while maintaining material security, as any attempt to falsify would result in an invalid verification code that fails the inspector's verification check.
Solution Approach 2:
The verification code is generated in advance from the original material before any verification process occurs. This preliminary action creates a cryptographic or algorithmic link between the material and its verification identifier. When the inspector later verifies the code, it conclusively proves the material's authenticity without requiring the inspector to have accessed or stored the original material. This preliminary generation of verification information enables future verification while maintaining security and preventing falsification.
