Security Level Determining Unit for Document Output Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices lack effective mechanisms to ensure secure output of document data, particularly in scenarios where the security print setting is not satisfied, leading to potential information leakage.
Innovation Solution
An information processing device is equipped with a security level determining unit and an instructing unit that assesses the security level and adjusts the output method by either outputting a notification sheet or prompting for user authentication when the security level does not meet a predetermined condition, ensuring secure document data handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the security level determining unit and instructing unit are added to assess and adjust output methods, then information security is improved, but device complexity increases
Solution Approach 1:
The image processing device is enhanced with multi-functional units that serve multiple purposes: the security level determining unit not only assesses security levels but also integrates with the output control mechanism, while the instructing unit both monitors and adjusts output methods. This multi-functionality approach allows the device to maintain improved information security without proportionally increasing overall system complexity.
Solution Approach 2:
The patent introduces an intermediary instruction output unit that acts as a mediator between the security assessment mechanism and the final output execution. This intermediary component receives security level assessments and translates them into appropriate output method adjustments, thereby implementing security control without requiring direct complex integration between all system components.
2Reliability
If the output method is changed to a high security level method, then information leakage prevention is improved, but productivity decreases
Solution Approach 1:
The patent implements dynamic output method adjustment based on real-time security level assessments. The instructing unit dynamically changes output methods according to the determined security level, allowing the system to apply high security measures only when necessary rather than always using the most secure method. This dynamic adaptation maintains information leakage prevention while avoiding unnecessary productivity loss during low-risk operations.
Solution Approach 2:
The system changes operational parameters (output methods) based on security level determinations. When security levels are low, the system uses faster, more efficient output methods; when security levels are high, it switches to more secure but slower output methods. This parameter adjustment strategy ensures information leakage prevention while optimizing productivity according to actual security requirements.

AI summary
An information processing device includes a security level determining unit that determines a security level, the security level indicating a level of security related to leakage of information in an image processing device, and an instructing unit that changes an output method to an output method having a high security level and gives at least one of two instructions, in a case where the security level does not satisfy a predetermined condition, the two instructions including an instruction for outputting information notifying the output method that has been changed, and an instruction for outputting information prompting for change of the security level in the image processing device.
