Invalid Request Detection for Phishing Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often unintentionally provide personal information to illegitimate entities through phishing scams, where fraudulent websites mimic legitimate ones, leading to identity and monetary theft.
Innovation Solution
A processing system that receives data, compares it to predetermined criteria, and generates a notification if an invalid request is detected, such as a phishing attempt, allowing for user alert and central server analysis to determine the level of invalidity and update the status of the request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users access websites or respond to emails without verification, then ease of operation is improved, but reliability deteriorates due to phishing scams
Solution Approach 1:
The system performs preliminary verification of websites and emails before users interact with them. Invalid request indicators are determined in advance by comparing received data to predetermined criteria, and users are notified before they can be deceived, thus maintaining ease of operation while improving reliability
Solution Approach 2:
The system provides feedback to users about the validity of requests they encounter. By notifying users of potential phishing attempts through invalid request indicators, the system creates a feedback loop that allows users to make informed decisions, thereby maintaining operational ease while enhancing security
2Reliability
If a processing system analyzes all received data for validity, then reliability is improved, but device complexity increases
Solution Approach 1:
The system changes the parameter of validation from comprehensive analysis to criterion-based comparison. By using predetermined criteria and comparing specific portions of received data against these criteria, the system achieves reliable detection without requiring complex analysis of all data, thus improving reliability while controlling device complexity
3Reliability
If the system notifies users of potential phishing attempts, then reliability is improved, but loss of time occurs due to notifications
Solution Approach 1:
The system applies partial action by notifying users only when invalid request indicators are determined, rather than requiring full verification of all communications. This selective notification approach provides adequate protection while minimizing time loss, as users are alerted only to potentially harmful requests

AI summary
A method of determining an indication of an invalid request, the method including the steps of, in a processing system: receiving data at step 100, comparing at least a portion of the received data to predetermined criteria at step 110, determining an indication of an invalid request included in the data at step 120, and generating a notification in accordance with the determined invalid request at step 140.
