Control Device for Fraudulent Email Detection and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to accurately detect fraudulent emails in business email compromise (BEC) attacks, which poses a significant risk to computer security within target companies.
Innovation Solution
A control device and detection system that generates and displays side-by-side information regarding potentially fraudulent emails, utilizing header information to identify suspicious email patterns and alert administrators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple pieces of information regarding fraudulent emails are displayed separately, then information completeness is improved, but information comprehensibility deteriorates
Solution Approach 1:
The patent combines multiple separate information elements (sender address, subject, detection timing, detection device) into a single integrated display unit. This allows all relevant fraudulent email information to be presented together in one location, maintaining information completeness while improving comprehensibility by eliminating the need to search across multiple separate displays.
Solution Approach 2:
The patent transitions from displaying information sequentially or in separate locations to presenting multiple information dimensions simultaneously in a unified display structure. By organizing information vertically or horizontally within a single display unit, the system accommodates multiple data points without increasing spatial complexity for the user.
2Measurement precision
If detailed email information is displayed, then detection accuracy is improved, but display complexity increases
Solution Approach 1:
The display unit is segmented into distinct information fields (sender address, subject, detection timing, detection device) while maintaining a unified structure. This segmentation allows detailed information to be presented clearly without creating overall display complexity, as each element has a defined position and purpose within the integrated display unit.
