Network Device Log Filtering for Ownership Data Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing log information in network devices do not account for changes in device ownership, leading to potential leaks of personal information and increased operational costs due to frequent real-time data transmission.
Innovation Solution
A network device that collects and accumulates log information, comparing event occurrence times with the contract start time to filter out data generated before the current ownership period, ensuring secure and batched transmission only to the new owner's storage region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time transmission of log information is performed, then information availability is improved, but the number of connections increases and operating costs increase
Solution Approach 1:
The patent implements periodic batch transmission of log information instead of continuous real-time transmission. The network device accumulates log information and transmits it to the storage server at predetermined intervals, reducing the frequency of connections while maintaining information availability through scheduled updates.
2Loss of energy
If batched transmission of log information is performed, then operating costs are reduced, but log information from previous contracts may be transmitted to the wrong storage region
Solution Approach 1:
The patent performs preliminary filtering of log information based on the contract start time before transmission. The network device compares the occurrence time of each log event with the contract start time and excludes events that occurred before the contract began, ensuring that only log information belonging to the current contract period is transmitted to the correct storage region.
Solution Approach 2:
The patent extracts and removes log information related to previous contracts from the batched data before transmission. By identifying and separating out events that occurred before the current contract start time, the system ensures that only relevant log information for the current contract is transmitted, preventing data misplacement while maintaining cost efficiency.
3Quantity of substance
If all log information is transmitted, then complete data collection is achieved, but personal information from previous owners may be leaked
Solution Approach 1:
The patent extracts and excludes log information related to previous contract periods before transmission. By filtering out events that occurred before the current contract start time, the system prevents personal information from previous owners from being transmitted to the new owner's storage region, thereby avoiding information leaks while maintaining complete data collection for the current contract period.

AI summary
A network device is allowed to be connected to a server via a network. The network device collects log information for an event that occurs inside of the network device, accumulates the log collected information, and transmits the accumulated log information to the server via the network. In addition, the network device compares a time of occurrence for the event with a contract start time for a current ownership contract for the network device, and performing filtering such that log information for one or more events that occurred before the contract start time among the accumulated log information is not transmitted to the server.
