Image Processing Malware Detection and Source Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses fail to effectively suppress the spread of malware infection during data transmission and reception, particularly when vulnerable devices with insufficient anti-malware measures are used, leading to potential infections in other devices.
Innovation Solution
An image processing apparatus equipped with a data receiver, malware checker, and reception restrictor that receives user and device information, checks for malware, and restricts data reception from specific sources upon detection, using a linkage table to identify and isolate infected users and devices to prevent further infection.

Engineering Contradiction Analysis
1Productivity
If data exchange is conducted frequently between information processing apparatuses, then productivity and data sharing capability are improved, but the risk of malware spread increases
Solution Approach 1:
The system performs preliminary malware detection on received data before allowing it to be processed or stored. The malware checker analyzes incoming data in advance, and the reception restrictor prevents acceptance of data from compromised sources before infection can spread to other apparatuses.
Solution Approach 2:
The system implements feedback mechanisms where the malware detection results are fed back to control the reception restrictor. When malware is detected, the system uses this feedback information to restrict future data reception from the same source, creating a adaptive security response loop.
2Reliability
If reception restriction is imposed on data from infected sources, then malware spread is suppressed, but data availability and user convenience deteriorate
Solution Approach 1:
The reception restrictor applies different quality levels to different data sources. Instead of blocking all data universally, it selectively restricts data from specific sources identified as compromised while allowing data from trusted sources to pass through uninterrupted.
Solution Approach 2:
The system segments the data reception function into controlled paths. The reception restrictor creates separate channels for trusted and untrusted sources, allowing selective data flow based on source reliability, thus maintaining data availability from safe sources while blocking malicious data.
Data Source
AI summary
An image processing apparatus includes a data receiver which receives, from outside, data including user information and device information; a storage which stores the data; a malware checker which checks whether the received data includes malware; and a reception restrictor which restricts, on or after detection of the malware from the data by the checking, reception of at least specific data from the outside. The specific data is, if a user is specifiable based on the user information, data related to the user, and is, if a device which has provided the data is specifiable based on the device information, data provided from the device.
