Anti-Phishing Link Disabling and Warning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Phishing attacks pose a significant threat as they can steal personal identity data and financial information, with spoofed emails being difficult to identify, leading users to unsafe websites or malicious code downloads.
Innovation Solution
An anti-phishing protection system that filters messages to mark and disable links within phishing emails, displaying a warning to users and allowing them to optionally enable links after being informed about the potential danger, with future accesses showing enabled links if user consent is given.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If links in phishing emails are disabled by default, then user security is improved, but user convenience deteriorates
Solution Approach 1:
The system performs preliminary identification and marking of phishing emails before the user interacts with them. Links in identified phishing emails are automatically disabled in advance, preventing potential harm while the user reads the email. This preliminary protective action resolves the contradiction by establishing security measures before the user encounters the threat.
Solution Approach 2:
The link disabling mechanism is dynamic rather than static. Links can be enabled or disabled based on the system's assessment of email authenticity. Users can interact with the system to enable links in legitimate emails marked as phishing, or have links automatically re-enabled based on further verification. This dynamic adjustment resolves the contradiction by adapting the security measure to the actual threat level.
2Reliability
If phishing emails are automatically identified and marked, then protection effectiveness is improved, but false positive rate increases
Solution Approach 1:
Rather than applying a uniform marking to all potentially suspicious emails, the system applies different levels or types of marking based on the specific characteristics and risk assessment of each email. This localized approach allows the system to maintain high protection effectiveness for genuine phishing attempts while reducing false positives for legitimate emails that share some characteristics with phishing emails.
Solution Approach 2:
The system incorporates feedback mechanisms where user interactions with marked emails (such as enabling links or reporting false positives) are used to refine and improve the identification algorithm. This feedback loop allows the system to learn from mistakes and reduce false positives over time while maintaining effective protection against actual phishing threats.

AI summary
Anti-Phishing protection assists in protecting against phishing attacks. Any links that are contained within a message that has been identified as a phishing message are disabled. A warning message is shown when the phishing message is accessed. The first time a disabled link within the phishing message is selected a dismissible dialog box is displayed containing information about how to enable links in the message. After the user dismisses the dialog, clicking on a disabled link causes the warning message to flash drawing the user's attention to the potential severity of the problem. The links may be enabled by the user by selecting the warning message and choosing the appropriate option. Once the user enables the links, future displays of the message show the links as enabled.
