Image Processing Apparatus for Secure Document Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing technologies fail to effectively prevent access to dangerous network resources, either by leaving dangerous link information in the output or removing it without notification, leading to potential security risks.
Innovation Solution
An image processing apparatus and method that extracts identification information from input document data, determines the safety of the network resource, and either restricts output or modifies the identification information to prevent access to dangerous resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If link information indicating dangerous access destinations is deleted from output image data, then security risk is reduced, but the original image data loses information about the link
Solution Approach 1:
The patent extracts and removes the harmful link information from the output image data while preserving the rest of the image content. The link information is specifically identified and separated from the original image data, allowing selective deletion of only the dangerous elements rather than the entire image or useful information.
Solution Approach 2:
The patent converts the harmful link information into a beneficial notification system. By detecting dangerous links, the system can alert users to potential security risks while still allowing them to view the image content. The harmful element (link information) becomes the basis for a protective notification mechanism.
2Loss of information
If link information is retained in output image data, then information completeness is maintained, but security risk increases due to potential accidental access
Solution Approach 1:
The patent introduces a notification as an intermediary between the link information and the user. The notification system acts as a mediator that alerts users to potential security risks before they can accidentally access dangerous destinations. This intermediary layer preserves the link information in the image while adding a protective warning mechanism.
3Object-affected harmful factors
If notification is provided to users about dangerous links, then security awareness is improved, but user experience may be degraded due to alerts
Solution Approach 1:
The patent applies notifications locally only to specific dangerous link locations within the image rather than providing global or intrusive alerts. The notification is positioned near or at the harmful link information, providing targeted security awareness without overwhelming the user with system-wide warnings that would degrade overall user experience.
Data Source
AI summary
Identification information corresponding to a network resource is extracted from input document data. It is determined whether access to the network resource is appropriate based on the identification information. Based on a result of determination, the output of the document data is restricted, or at least part of the identification information is changed, and the document data is output.
