Image Forming Apparatus Security Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunction devices face issues where enhancing the security level can result in users being unable to access stored jobs that do not meet new password regulations, leading to confusion and potential data loss, as jobs not satisfying security requirements are either deleted or inaccessible.
Innovation Solution
An image forming apparatus with a determination portion to identify jobs not meeting security requirements, an execution portion to process these jobs to meet security standards, and a security mode switching portion to enhance the security level only after processing is complete, ensuring job execution and data protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the security level is enhanced, then security requirements are improved, but users cannot access stored jobs that do not meet new password regulations
Solution Approach 1:
The system performs preliminary processing of stored jobs to update passwords and security settings before the security mode enhancement takes effect. This allows jobs to be pre-adapted to new security requirements, ensuring both enhanced security and continuous job accessibility without user confusion or data loss.
Solution Approach 2:
The system dynamically adjusts security settings for individual jobs based on the enhancement timing. Jobs are selectively updated with new password regulations only when necessary, allowing the security level to be enhanced while maintaining flexibility in job access. This dynamic approach prevents rigid security enforcement that would block access to existing jobs.
2Reliability
If the security level is enhanced, then security requirements are improved, but stored jobs not satisfying requirements are deleted or become inaccessible
Solution Approach 1:
The system performs preliminary processing of stored jobs to update passwords and security settings before the security mode enhancement takes effect. This prevents deletion of jobs by proactively adapting them to new security requirements, thereby maintaining job data integrity while achieving enhanced security.
Solution Approach 2:
The system converts the potential harm of job deletion into a benefit by automatically updating job security settings. Instead of deleting jobs that don't meet new security requirements, the system enriches these jobs with updated security parameters, transforming a security enforcement mechanism into a job preservation and enhancement process.
3Reliability
If the security level is enhanced, then security requirements are improved, but operation complexity increases
Solution Approach 1:
The system performs self-service by automatically processing and updating stored jobs to meet new security requirements. The enhancement process is executed autonomously without requiring user intervention to modify individual job settings, thereby reducing operational complexity while maintaining enhanced security standards.
Solution Approach 2:
The system performs preliminary processing of all stored jobs before security mode enhancement completes. This batch processing approach consolidates complexity into a single automated operation rather than requiring multiple individual user actions, simplifying the overall enhancement process while ensuring comprehensive security compliance.

AI summary
An image forming apparatus is provided with a determination portion that, in response to operation for giving instructions to enhance a security level thereof, determines whether or not a job is kept which is not to satisfy security requirements after the enhancement, an execution portion that, if the determination portion determines that such a job is kept, performs predetermined processing for satisfying the security requirements on the job with execution of the job ensured, and a security mode switching portion that, if the determination portion determines that such a job is kept, enhances the security level after the execution portion finishes the predetermined processing, and, if the determination portion determines that such a job is not kept, enhances the security level promptly.
