Fraud Detection System Using Preliminary User Action Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fraud detection systems take a long time to complete processing after detecting a detection target due to the need for fraud detection, which prolongs the time before predetermined processing can be executed.
Innovation Solution
A fraud detection system that determines whether a predetermined action has been performed by a user before detection, executes fraud detection based on identification information stored in the user terminal, and then performs predetermined processing upon detection, thereby shortening the overall time required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fraud detection is executed after detection target is detected, then fraud detection accuracy is ensured, but processing time is excessively long
Solution Approach 1:
The system executes fraud detection in advance by monitoring predetermined actions (such as code generation, copying, or distribution actions) before the detection target is actually used. This preliminary fraud detection based on user behavior patterns allows the system to pre-determine fraud risk, so that when the detection target is subsequently detected, the processing can be completed quickly using the pre-obtained fraud determination result, thereby resolving the contradiction between ensuring detection accuracy and reducing processing time
2Loss of time
If fraud detection is executed before detection target is detected, then processing time is shortened, but system complexity increases
Solution Approach 1:
The system performs preliminary fraud detection by monitoring specific predetermined actions (code generation, copying, distribution) that are naturally occurring in the workflow. This approach avoids the need for continuous comprehensive monitoring, thereby limiting the increase in system complexity to only the extent necessary for detecting these specific actions, while still achieving the benefit of shortened processing time
3Reliability
If continuous monitoring is performed to detect predetermined actions, then fraud detection accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the system performs periodic detection by monitoring only when specific predetermined actions occur (code generation, copying, or distribution actions). This event-driven approach ensures high fraud detection accuracy by focusing on critical moments while significantly reducing energy consumption by avoiding constant monitoring, thus resolving the contradiction between reliability and energy usage

AI summary
A fraud detection system for executing predetermined processing when a detection target is detected by using a detection device, the fraud detection system comprising at least one processor which determines, before the detection target is detected, whether a predetermined action has been performed by a user having a user terminal; executes, when it is determined that the predetermined action has been performed, fraud detection on the user based on identification information stored in the user terminal; and executes, when the detection target is detected, the predetermined processing based on an execution result of the fraud detection.
