Controller Virus Detection and Access Restriction for Job Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses face challenges in preventing repeated reception of job information infected with viruses from the same user, as users may continue using the apparatus without realizing the infection.
Innovation Solution
An information processing apparatus with a controller that determines if job information is infected with a virus, stores use restriction information associated with user authentication, and restricts access when a virus is detected, allowing for individual function-level restrictions and subsequent release of restrictions upon user education or administrator approval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information processing apparatus detects a virus in job information, then the virus detection capability is improved, but the user may continue to use the apparatus without noticing the infection, leading to repeated reception of infected job information
Solution Approach 1:
The system performs preliminary action by storing use restriction information in advance when a virus is detected. This pre-established restriction mechanism ensures that when the same user submits job information again, the previously stored restriction information is automatically retrieved and applied, preventing repeated virus transmission without requiring continuous monitoring or user awareness.
Solution Approach 2:
The system implements feedback by retrieving previously stored use restriction information and applying it to subsequent job information from the same user. This feedback loop creates a closed control system where the detection result (virus found) feeds back into the authentication process, automatically restricting the user's ability to submit more job information until the restriction is cleared.
2Object-affected harmful factors
If the apparatus restricts use by a user whose job information is infected with a virus, then the spread of virus is prevented, but the user cannot access the apparatus even after correcting the issue
Solution Approach 1:
The use restriction is designed to be dynamic rather than static. The restriction information stored in the system can be updated or deleted based on current conditions. When a user's job information is no longer infected (as verified by重新 detection), the corresponding use restriction information is removed or updated, automatically restoring the user's access rights without requiring system reconfiguration or administrator intervention.
Solution Approach 2:
The system provides self-service functionality by automatically managing the lifecycle of use restrictions. When job information from a restricted user is submitted and found to be free of viruses, the system automatically retrieves the authentication information, checks the current infection status, and removes the use restriction if the job information is clean. This self-correcting mechanism eliminates the need for manual administrator intervention to restore user access.
3Measurement precision
If the information processing apparatus continuously monitors all job information for viruses, then the detection thoroughness is improved, but the processing time and system load increase
Solution Approach 1:
The system applies local quality by differentiating the level of inspection based on user history. First-time users or users without prior restrictions have their job information fully scanned for viruses. However, users who have already been restricted and have subsequently submitted clean job information are granted trusted status, where their future job information may be subjected to lighter or no virus scanning, as the system has already verified their reliability.

AI summary
An information processing apparatus includes a controller that, upon reception of job information accompanied by authentication information capable of specifying a user, determines whether the job information is infected with a virus or not, wherein the controller: causes use restriction information capable of specifying restriction of use by the user in association with the authentication information to be stored in a storage, when it is determined that the job information is infected with the virus; and restricts use of the information processing apparatus by the user specified by the authentication information associated with the use restriction information, when the use restriction information is stored in the storage.
