Document Data Tracking Without Centralized Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of managing document data, existing methods face challenges in tracing and managing large volumes of replicated data without the use of a server, leading to potential information leakage and high costs associated with centralized data management.
Innovation Solution
A method that combines document data with child and parent identification data, allowing for the management of document data without a server by incorporating event execution permission/denial determination and information exchange programs to determine and execute permissions, and exchange information across generations of document data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If document data is managed in a centralized server, then data traceability and security are improved, but system complexity and cost increase
Solution Approach 1:
The patent divides the centralized management system into distributed components. Each document data unit carries identification information that enables independent tracking. The management function is segmented across multiple nodes rather than concentrated in a single server, reducing system complexity while maintaining traceability.
Solution Approach 2:
Document data units autonomously carry their own identification information and can be tracked independently without requiring centralized server intervention. The data itself contains the means for its own identification and traceability, enabling self-service management that reduces system complexity.
2Ease of operation
If document data is replicated and distributed, then data accessibility and convenience are improved, but data security and control deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where identification information is embedded in replicated document data and traced back to the source. This allows the system to monitor and control data distribution while maintaining accessibility, providing feedback loops that ensure security without compromising ease of operation.
Solution Approach 2:
The identification information structure serves multiple functions simultaneously: it enables data tracing, security verification, and distribution control. This multi-functionality allows the system to maintain both data accessibility and security through a unified approach rather than separate mechanisms.
3Loss of information
If a centralized server is used to trace replicated data, then data location tracking is improved, but cost and system complexity increase
Solution Approach 1:
Document data units contain embedded identification information that enables self-tracking. The data carries its own location and origin information, eliminating the need for expensive centralized server infrastructure to track data locations. This self-service approach maintains complete tracking capability while dramatically reducing costs.
Solution Approach 2:
The patent extracts the tracking function from the centralized server and embeds it directly into the document data units themselves. By taking out the tracking mechanism from the server and placing it within the data, the system achieves location tracking without requiring expensive server infrastructure.
Data Source
AI summary
A method is provided which enables to know a location of copied document data without the use of a server or others. Document data that is data used for reconstructing a document is managed by combining, in one document object, the document data along with relationship information for identifying other document data generated by reproducing the document data. Likewise, when a reproduction process is performed, the other document data is managed by combining, in one document object, the other document data along with relationship information for identifying the reproduction.
