Visual Domain Verification for Phishing Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Phishing attacks are difficult to detect due to deceptive domain names and URLs that resemble authentic ones, with existing user interfaces and browsers providing limited visual indications of mistakes, and truncated links that hinder users' ability to inspect complete domain names or URLs.
Innovation Solution
Implementing a visual verification system that displays a popularity ranking and age of domain names, with a security application determining if a domain is unpopular or new, and rendering visual indicators to alert users, and providing complete URL visibility before navigation, to prevent accidental access to phishing sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual indicators showing popularity ranking and age of domain names are displayed, then user awareness and security are enhanced, but device complexity increases
Solution Approach 1:
The security evaluation system is segmented into multiple independent components: a security application that identifies domain names, a determination module that evaluates popularity and age, and a rendering module that displays visual indicators. This segmentation allows the complex security verification function to be broken down into manageable, modular operations that can be executed efficiently without overwhelming the device.
Solution Approach 2:
The system performs preliminary evaluation of domain names by determining their popularity ranking and age before the user interacts with them. The security application proactively identifies domain names in communications and pre-assesses their security risk characteristics, so that when visual indicators need to be displayed, the evaluation work has already been completed, reducing real-time processing complexity.
2Loss of information
If complete URL visibility is provided before navigation, then users can inspect domain names and exercise caution, but information overload may occur
Solution Approach 1:
Instead of displaying all URL information uniformly, the system applies local quality by providing different levels of visibility and detail for different parts of the URL based on their security significance. Complete domain names and URLs are displayed in contexts where security verification is critical, while less critical information may be shown in truncated or summarized forms, allowing users to focus on the most important security-relevant details without being overwhelmed by excessive information.
3Reliability
If visual indicators for unpopular or new domains are displayed, then phishing detection is improved, but user experience may be degraded due to false warnings
Solution Approach 1:
The system uses parameter changes by evaluating multiple characteristics of domain names (popularity ranking, age, and other security-relevant parameters) rather than relying on a single threshold. By considering combinations of parameters and their relative weights, the system can distinguish between genuinely suspicious domains that require warnings and legitimate new or less-popular domains that should not trigger false alarms, thereby improving phishing detection while minimizing user experience degradation.

AI summary
Techniques for providing domain name and URL visual verifications to increase security of operations on a device. The techniques include a visual indicator and/or warning to a user on the user's computing device that a domain or URL requested by the user and the device is unpopular, new, unknown, inauthentic, associated with malware or phishing, or in some other way, risky. The techniques include identifying a domain name in a communication received by a computing device and then determining a popularity ranking and/or an age of the domain name. The device can render, for display on a screen of the device, a visual indicator having the popularity ranking and/or the age of the domain name. Also, the techniques can include identifying a URL in a communication received by a computing device and then rendering, for display on a screen of the device, a visual indicator having the entire URL.
