Digital Document Management with Partial Correction Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital document management systems fail to effectively identify and validate partial corrections, such as additions, changes, or deletions, in digital documents, especially when distributed among multiple entities, and struggle with third-party certification, particularly when parts of the document are hidden or sanitized.
Innovation Solution
A digital document management system that includes a policy information storage section, partial identification information generation, partial correction information generation, and a registration document verification section, using hash functions and XML data structures to manage and verify document integrity, ensuring that corrections are made according to established policies and can be validated by third parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital document management systems use conventional correction methods, then document corrections can be made, but the corrected parts cannot be clearly identified and validated
Solution Approach 1:
The patent segments the digital document into individual character units, assigning unique identification information to each character. This segmentation enables precise tracking of which specific characters have been corrected, allowing clear identification of corrected parts without requiring complex overall document verification mechanisms.
Solution Approach 2:
The patent introduces correction information as an intermediary data structure that records the relationship between original characters and corrected characters. This intermediary mechanism enables validation of corrections by providing a clear audit trail without requiring direct modification of the original document structure, thus maintaining system simplicity while achieving precise identification.
2Reliability
If digital document management systems store complete document versions, then document integrity can be maintained, but storage space and processing time increase
Solution Approach 1:
The patent extracts only the necessary identification information (unique identifiers for characters) from the complete document data and stores this extracted information in a separate management table. This extraction approach maintains document integrity by preserving the character-level identification data while significantly reducing the storage volume required compared to storing complete document versions.
Solution Approach 2:
The patent creates a simplified copy of the document structure in the form of a management table that contains only the essential identification information needed for validation. This copy mechanism allows integrity verification without storing the full document data, thus maintaining reliability while reducing storage requirements.
3Adaptability or versatility
If digital document management systems allow partial corrections, then document flexibility improves, but verification of correction validity becomes difficult
Solution Approach 1:
The patent implements a feedback mechanism where correction information is recorded and stored in a structured format that enables automatic verification. The system provides feedback by allowing users to query the management table to confirm whether specific corrections have been made and validated, thus making verification straightforward while maintaining document flexibility.
Solution Approach 2:
The patent replaces manual verification processes with automated electronic verification using the management table. Instead of requiring manual inspection of corrected parts, the system uses electronic queries against the stored correction information to automatically verify correction validity, significantly reducing verification difficulty while preserving document flexibility.
4Reliability
If digital document management systems implement third-party certification, then document authenticity is guaranteed, but system complexity and processing overhead increase
Solution Approach 1:
The patent performs preliminary action by pre-storing correction information and identification data in the management table before third-party certification is required. This preliminary preparation enables rapid and simple certification processes, as the third party only needs to query the pre-organized management table rather than performing complex analysis, thus guaranteeing authenticity without excessive system complexity.

AI summary
A digital document management system is capable of guaranteeing that a partial correction has been made according to a proper procedure and achieving a third-party certification of the validity of the guarantee. The digital document management system manages document information created in a digital form, and includes partial identification information generation section that generates partial identification information that represents, in an identifiable manner, respective parts of the document information. A partial correction information generation section generates partial correction information which is information related to a correction history of a corrected part in the case where any correction has been required for the document information; and an original document information management section manages the document information, partial identification information, partial correction information, and prescribed policy information in an associated manner.
