Email Filtering via Domain Registration Date Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying and processing suspicious emails are often ineffective and time-consuming, frequently misclassifying legitimate emails as spam or phishing, and require additional software, making it difficult for companies to accurately block unauthorized or malicious emails.
Innovation Solution
A computing device determines the registration date of an email domain and compares it to a threshold date, using this information to execute a security risk assessment model, which filters emails based on the security risk level, allowing legitimate emails to pass through while blocking or redirecting potentially malicious ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If companies use algorithms to categorize incoming emails to identify spam and phishing emails, then email security detection capability is improved, but accuracy deteriorates causing legitimate emails to be incorrectly classified
Solution Approach 1:
The patent changes the parameter used for email classification from complex algorithmic analysis to domain registration date. By using the registration date as the key parameter, the system achieves more accurate differentiation between legitimate and suspicious emails, reducing misclassification of legitimate emails while maintaining security detection capability.
2Productivity
If companies use existing email filtering tools, then email processing capability is improved, but time consumption increases and additional software is required
Solution Approach 1:
The patent extracts the essential feature for email security assessment from the complex email data - specifically the domain registration date. By focusing only on this key parameter rather than analyzing all email attributes, the system achieves fast processing without requiring additional complex software tools, thereby reducing time consumption while maintaining productivity.
3Reliability
If companies implement comprehensive email security measures, then security coverage is improved, but system complexity increases
Solution Approach 1:
The patent simplifies the security assessment system by extracting and focusing on a single critical parameter - domain registration date. This approach provides comprehensive security coverage through a simple rule-based system rather than complex multi-parameter analysis, thereby reducing system complexity while maintaining or improving security coverage.
Data Source
AI summary
Aspects of the disclosure relate to identifying and processing suspicious emails. In some embodiments, a computing device may receive an email associated with an email domain. Subsequently, the computing device may determine a registration date of the email domain. The computing device may then compare the determined registration date to a first threshold date. Thereafter, responsive to determining that the determined registration date is before the first threshold date, the computing device may transmit the email to a recipient address identified in the email. Responsive to determining that the determined registration date is at or after the first threshold date, the computing device may execute a security risk assessment model. The computing device may then determine, based on the security risk assessment model, a security risk level of the email domain. The computing device may filter, based on the security risk level of the email domain, the email.
