Dynamic Document Concealment for Information Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems fail to provide user convenience when replacing elements in documents, as the uniform replacement process does not adequately address information leakage risks, leading to a lack of intended convenience for users.
Innovation Solution
An information processing system that manages target elements and concealment conditions, allowing for non-uniform concealment control based on the output place, replacing target elements with different replacement elements to prevent information leakage, while maintaining the external appearance uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform replacement process is applied to all target elements, then information leakage risk is reduced, but user convenience deteriorates
Solution Approach 1:
The patent applies different replacement elements to different target elements based on their specific characteristics and positions. Instead of uniform replacement, the system selects appropriate replacement elements (such as different placeholder texts, symbols, or formatting) according to the local context of each target element, thereby maintaining user convenience while still preventing information leakage.
Solution Approach 2:
The patent introduces dynamic concealment conditions that can be adjusted based on output destinations, user preferences, and document types. The replacement strategy is not fixed but adapts dynamically to different scenarios, allowing the system to balance information security requirements with user convenience needs in various contexts.
2Ease of operation
If different replacement elements are used for different target elements, then user convenience is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal concealment condition management system that can handle multiple replacement strategies through a single unified framework. The system uses a standardized set of concealment conditions that can be applied across different document types, output destinations, and target elements, reducing the need for separate complex control mechanisms for each scenario.
Solution Approach 2:
The patent pre-defines multiple concealment conditions and replacement element sets that can be selected based on the specific situation. By preparing these options in advance and organizing them in a structured manner, the system reduces the complexity of real-time decision-making and simplifies the concealment control process while still providing diverse replacement options.
3Adaptability or versatility
If concealment conditions are managed based on output place, then adaptability is improved, but management complexity increases
Solution Approach 1:
The patent segments the concealment condition management into distinct categories based on output destinations (such as email, print, web publication, etc.). Each output place type has its own predefined concealment conditions and replacement element sets, making it easier to manage and select appropriate conditions without having to handle all possible scenarios in a single complex system.

AI summary
An information processing system includes one or more processors configured to: manage a target element and a concealment condition, the target element serving as a concealment target and being included in an input document element of an input document, the concealment condition including at least a condition regarding an output place for outputting an output document in which concealment of the target element is performed; and on a basis of the concealment condition, perform concealment control to perform the concealment of the target element and perform output control to output the output document.
