Distributed Operation Data Processing for Confidential Instrument Analytics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Instrument manufacturers face challenges in protecting their proprietary calculation methods and operation data confidentiality, as owners may resist sharing operation data due to confidentiality concerns and legal regulations, necessitating a system that restricts data acquisition while safeguarding know-how.
Innovation Solution
A data processing system comprising an agent device, service broker device, and computation server device, where the agent device transmits operation data to the computation server through a first network, and the service broker relays data using a second network, with firewalls and encrypted communication protocols to limit data access and protect confidentiality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operation data is transmitted through a network for processing, then the manufacturer can protect their computational know-how, but the owner's data confidentiality and control are compromised
Solution Approach 1:
The patent segments operation data into multiple pieces and distributes them across different devices. The agent device holds first operation data, the service broker holds second operation data, and neither single device possesses the complete data set. This segmentation prevents any single device from accessing all operation data, thereby protecting confidentiality while enabling distributed processing.
Solution Approach 2:
The service broker device acts as an intermediary between the agent device and the computation server. It receives operation data from the agent, processes it without revealing the complete data set, and forwards results to the computation server. This intermediary structure enables data processing while maintaining data confidentiality through controlled access.
2Measurement precision
If complete operation data is made accessible for processing, then analysis accuracy improves, but data security and owner control deteriorate
Solution Approach 1:
Operation data is divided into multiple segments stored at different locations (agent device and service broker). The system processes these segmented data pieces together to achieve accurate analysis results without requiring any single device to hold the complete data set, thus maintaining both accuracy and security.
Solution Approach 2:
The patent implements a nested structure where the service broker contains and processes operation data segments, while the agent device contains additional operation data segments. This nested arrangement allows layered access control where inner layers (service broker) can process data without exposing it to outer layers (agent device), maintaining security while enabling analysis.
Data Source
AI summary
An agent device transmits certain data, which is used for generating display data, of data relating to a plurality of pieces of operation data collected from an instrument to a computation server device. A service broker device relays certain data transmitted from the agent device to the server device. The server device generates display data on the basis of certain data relayed by the service broker device.
