Information Processing Apparatus Virus Detection Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in avoiding overlapping virus detection processing, leading to unnecessary isolation of images even when their security has been ensured by other systems, resulting in user inconvenience and opportunity loss.
Innovation Solution
An information processing apparatus that receives and stores files, performs virus detection processing, and determines file normality, ensuring that files already guaranteed as normal are not unnecessarily isolated, even if errors occur in the detection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virus detection processing is performed in multiple stages (imaging apparatus, external service, and information processing apparatus), then security assurance is improved, but overlapping execution causes unnecessary image isolation and availability loss
Solution Approach 1:
The patent applies preliminary action by having the imaging apparatus or external service perform virus detection before image transmission to the information processing apparatus. The detection result is recorded in metadata ahead of time, allowing the information processing apparatus to use this pre-obtained information and avoid redundant detection and subsequent isolation of safe images.
Solution Approach 2:
The patent implements feedback by having the information processing apparatus refer to the virus detection result recorded in metadata from previous detection stages. This feedback mechanism allows the system to learn from prior detection outcomes and adjust its behavior, preventing unnecessary isolation of images that were already confirmed safe in earlier stages.
2Reliability
If virus detection processing is executed automatically at storage timing, then security is maintained, but inability to control execution timing causes overlapping processing and user inconvenience
Solution Approach 1:
The patent applies preliminary action by performing virus detection before image storage in the information processing apparatus, using detection results from imaging apparatuses or external services that occur prior to storage. This eliminates the need for automatic detection at storage timing, giving users more control while maintaining security through advance detection.
Solution Approach 2:
The patent implements dynamics by making the virus detection timing flexible rather than fixed. The system can adaptively determine when detection occurs based on metadata from previous stages, allowing users to control the process flow while the system automatically handles security maintenance through recorded detection results.
3Reliability
If detection errors are treated as virus infections, then false positives are avoided, but legitimate images are unnecessarily isolated causing opportunity loss
Solution Approach 1:
The patent applies preliminary action by having the imaging apparatus or external service perform virus detection and record results in metadata before image transmission. This pre-detection allows the information processing apparatus to trust prior verification results and avoid re-isolating images that were already confirmed safe, preventing opportunity loss from redundant detection errors.
Solution Approach 2:
The patent implements feedback by having the information processing apparatus reference the virus detection result recorded in metadata from previous detection stages. This feedback mechanism allows the system to learn from prior detection outcomes and adjust its behavior, preventing unnecessary isolation of images that were already confirmed safe in earlier stages.

AI summary
An information processing apparatus includes at least one processor and at least one memory, cooperating to receive a file, store the received file, perform virus detection processing on the file, determine whether the file is a normal file in a case where it is determined that the file is suspected of being infected with a virus or that the file is guaranteed as the normal file although an error occurs in the virus detection processing, as a result of the virus detection processing.
