Embedded Modification History in Editable Electronic Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for managing modification history of images represented by electronic files are cumbersome, requiring users to manually look up past files or data management servers to confirm changes, which is time-consuming and inconvenient.
Innovation Solution
An information processing apparatus that includes an image reading device, a control device, and an input device, where the control device generates editable electronic files and adds a modification history to the source image upon user input, allowing the modification history to be stored and displayed within the image itself, enabling easy tracking of changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If modification history is stored separately from the image file, then the image file remains simple and lightweight, but users must manually search through past files or access data management servers to confirm changes, which is time-consuming and inconvenient
Solution Approach 1:
The patent merges the modification history information with the image file by embedding it as metadata within the file structure. This integration allows users to access modification history directly from the image file without needing to separately search through past files or access external data management servers, thereby improving ease of operation while maintaining file organization
2Loss of time
If modification history is embedded within the image file, then users can easily confirm changes without searching through past files, but the file structure becomes more complex
Solution Approach 1:
The patent implements a nested structure where modification history metadata is embedded within the image file structure. The metadata is organized in a hierarchical manner with version information, timestamp, and modification details nested within the file's metadata section, allowing efficient storage and retrieval without significantly increasing overall file complexity
Solution Approach 2:
The patent creates a simplified copy or representation of modification history information that can be easily extracted and displayed. Instead of storing complex historical data structures, the system maintains essential modification records (version, timestamp, basic changes) that can be quickly accessed and presented to users, reducing the effective complexity while preserving the time-saving benefit
Data Source
AI summary
An information processing apparatus includes an image reading device, a control device, and an input device. The image reading device reads a source document and generates image data. The control device acts as a controller that generates an editable electronic file from the image data. The input device is to be used by a user to input an instruction. The controller adds, upon receipt of a modification of the source image represented by the electronic file, through the input device, a modification history based on the modification made, to the modified source image.
