Browser Extension for Counterfeit Website Detection and Takedown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Counterfeit websites pose a significant threat by deceiving users into providing sensitive information or downloading malicious content, and existing methods lack effective real-time detection and takedown solutions.
Innovation Solution
A browser extension integrated with a counterfeit URL detection system that intercepts URL requests, analyzes webpage content using a trained model, and blocks access to counterfeit sites, while also providing analytics and redirecting users to legitimate URLs, and implementing methods for takedown of counterfeit websites through API or email notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time detection and blocking of counterfeit websites is implemented, then user safety is improved, but system complexity and computational resources increase
Solution Approach 1:
The system pre-generates security certificates for legitimate websites before they are potentially accessed by users. When a website is registered or becomes active, its certificate is pre-computed and stored in the browser extension's whitelist database. This preliminary action enables instant verification without real-time computational overhead during user browsing, resolving the contradiction between rapid detection and system complexity.
Solution Approach 2:
The browser extension autonomously verifies website certificates against the pre-generated whitelist without requiring manual user intervention or complex real-time analysis. The extension automatically blocks access to counterfeit sites by checking whether the visited website's certificate exists in its local whitelist, enabling self-service security protection that simplifies the overall system architecture.
2Measurement precision
If comprehensive website analysis is performed to detect counterfeit sites, then detection accuracy is improved, but processing time increases
Solution Approach 1:
The system extracts only the essential certificate information (domain name and validity status) from website responses and stores it in a compact whitelist format. Instead of analyzing complete website content or performing complex real-time cryptographic verification, the extension extracts and compares only the critical certificate identifiers against the pre-stored whitelist, achieving high detection accuracy with minimal processing time.
Solution Approach 2:
Certificate verification data is pre-computed and stored in the whitelist before users need it. The system performs the time-consuming certificate analysis in advance during website registration or setup, then stores the results in an easily queryable format. This eliminates the need for time-consuming real-time analysis when users visit websites, resolving the contradiction between comprehensive verification and processing speed.

AI summary
Disclosed herein are systems and methods for automatic takedown of counterfeit websites using API-based and/or email-based takedown. In implementations the method includes checking the domain of a Uniform Resource Locator (URL) against a database to determine if an API-based takedown can be performed for the counterfeit website. If an API-based takedown cannot be performed the system determines the email of the hosting provider hosting the counterfeit website based on the resolve Internet Protocol (IP) address and sends a takedown notification via email with evidence such as screenshots, hosting infrastructure information, website lifecycle and scan timestamp. The system checks periodically whether the counterfeit website has been taken down by the network owner. If, after a check, the website is still live, the process of takedown is repeated until the website is taken down.
