Email Link Security Prompting via Preliminary Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face security risks when using email services due to malicious links in emails, which can lead to property damage, privacy issues, and software installations without consent.
Innovation Solution
A method and device that extract information from opened emails to determine if unsafe webpage links are present, prompting users with security alerts to prevent clicking on potentially harmful links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users click on links in e-mails to access information or services, then convenience and information access are improved, but security risks increase due to malicious links
Solution Approach 1:
The system performs preliminary detection of e-mail links before the user clicks them. The detection unit scans links in advance, checks them against a malicious link database, and identifies potential threats before interaction occurs, preventing security incidents while maintaining user convenience
Solution Approach 2:
The system introduces an intermediary detection mechanism between the user and the e-mail links. The detection unit acts as a mediator that intercepts link analysis, compares URLs against the malicious database, and provides warning information to users, thereby blocking harmful interactions without affecting legitimate ones
2Reliability
If security detection mechanisms are added to e-mail systems, then security is improved, but system complexity increases
Solution Approach 1:
The system extracts only the essential security detection function from the complex e-mail system. The detection unit is a standalone module that specifically handles link analysis by comparing URLs against the malicious link database, separating this security function from other e-mail operations to minimize overall system complexity
Solution Approach 2:
The system uses a simplified copying approach by maintaining a database of malicious link patterns and URLs. Instead of implementing complex real-time analysis algorithms, the detection unit copies and compares link structures against known malicious patterns, providing effective security through pattern matching rather than sophisticated computation

AI summary
The present invention discloses a method and a device for prompting information about an e-mail. The method comprises: extracting information from a currently opened e-mail; according to the extracted information, determining whether an unsafe webpage link is contained in content of the currently opened e-mail; and if yes, providing security prompting information to a user. By means of the present invention, security is ensured when a person uses an e-mail box.
