Dummy Information Insertion for Irreplaceable Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques struggle to effectively input dummy information into systems to counter reconnaissance activities by attackers, particularly when the attacker seeks genuine information irreplaceable with dummy information, and are limited in their applicability to specific types of setting information.
Innovation Solution
A device and method that determine a second location for inserting dummy information based on first location information and insertion conditions, ensuring the dummy information resembles the irreplaceable genuine information and is not present in the computer or local network, allowing for versatile dummy information insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dummy information is inserted into replaceable genuine information, then detection accuracy improves, but applicability is limited to only replaceable information types
Solution Approach 1:
The patent segments information into three categories: replaceable genuine information, irreplaceable genuine information, and dummy information. This segmentation allows the system to apply different strategies to different information types, enabling dummy information insertion while preserving critical irreplaceable information through alternative protection mechanisms.
Solution Approach 2:
The system performs preliminary identification of information types before insertion. By classifying information as replaceable or irreplaceable in advance, the system can prepare appropriate protection strategies, including inserting dummy information into replaceable locations and applying other defensive measures to irreplaceable information.
2Adaptability or versatility
If dummy information is inserted into irreplaceable genuine information, then versatility of protection improves, but system stability deteriorates due to potential operational failures
Solution Approach 1:
The patent introduces an intermediary identification mechanism that mediates between the need for versatile protection and system stability. This intermediary layer classifies information types and directs appropriate protection strategies, preventing direct insertion of dummy information into irreplaceable data while still providing comprehensive protection coverage.
Solution Approach 2:
The system changes the parameter of information protectability by introducing a protectability classification parameter. Information is evaluated based on whether it can be protected through dummy insertion (replaceable) or requires other methods (irreplaceable), allowing versatile protection while maintaining stability through parameter-based decision making.
3Measurement precision
If comprehensive dummy information insertion is implemented, then detection capability improves, but device complexity increases
Solution Approach 1:
The patent applies local quality by providing different levels of protection to different information locations. Replaceable information receives dummy information insertion for enhanced detection, while irreplaceable information receives alternative protection. This localized approach improves overall detection capability without uniformly increasing complexity across the entire system.
Solution Approach 2:
The system performs preliminary classification of information locations before implementing protection measures. By identifying replaceable versus irreplaceable information in advance, the system can apply appropriate protection strategies without requiring complex real-time decision-making, thereby reducing overall device complexity while maintaining detection capability.

AI summary
Provided is a more versatile technique that makes it possible to input dummy information in response to an attacker seeking to collect normal information that cannot be replaced with dummy information. In the present invention, a dummy information insertion device inserts dummy information into a second location that is determined using: first location information indicating a first location that contains normal information, from among all normal information in a computer, which cannot be replaced with other information; and insertion condition information that indicates conditions for determining the second location into which dummy information is to be inserted, with such dummy information resembling the normal information that cannot be replaced and not being present in the computer or in a local network connected to the computer.
