Electronic Interface Device for Multi-Policy Data Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic interface devices fail to ensure full compliance with sensitivity requirements of data exchanged between networks obeying different data labeling policies, leading to inadequate control over the dissemination of sensitive data.
Innovation Solution
An electronic interface device comprising a first interface unit with a filtering module configured according to a first data labeling policy, a second interface unit with a filtering module configured according to a second data labeling policy, and a transposition unit that transposes labels between the two policies, ensuring filtering at both input and output based on specific network policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single filtering module is used at the interface between two networks, then the device complexity is reduced, but the reliability of data sensitivity control deteriorates because it cannot comply with both different labeling policies simultaneously
Solution Approach 1:
The filtering function is segmented into two independent filtering modules: a first filtering module for the first network's labeling policy and a second filtering module for the second network's labeling policy. Each module independently filters data according to its respective policy, ensuring that both networks' sensitivity requirements are met without compromising either one.
Solution Approach 2:
A transposition unit acts as an intermediary between the two filtering modules. It transposes labels from the first labeling policy to the second labeling policy and vice versa, enabling the filtering modules to understand and enforce both policies correctly. This mediator resolves the conflict between different labeling systems.
2Ease of operation
If filtering rules are configured for only one labeling policy, then the ease of operation is improved, but the adaptability to multiple network policies deteriorates
Solution Approach 1:
The interface device achieves multi-functionality by incorporating both a first filtering module and a second filtering module, each capable of enforcing different labeling policies. The transposition unit enables these modules to work together, allowing the device to adapt to multiple network policies simultaneously while maintaining straightforward operation through automated label transposition.
