Proxy Website Detection Using Advertising Account ID Signatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and methods to enforce policies effectively with respect to proxy communications, as existing technologies lack efficient mechanisms to identify and block proxy websites, which can compromise security and access control.
Innovation Solution
The proposed solution involves analyzing website content for patterns similar to those of known non-proxy websites, comparing identifiers, and categorizing suspected proxy websites, with methods including intercepting requests, analyzing content for checksums, and blocking interactions based on mismatches or suspicious patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If website content analysis is performed to identify proxy websites, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the website content analysis into multiple independent components: extracting website identifiers, retrieving signature content from databases, comparing identifiers, and analyzing content patterns. Each component operates independently and contributes to the overall detection accuracy without requiring the entire system to be complex.
Solution Approach 2:
The patent performs preliminary actions by pre-collecting and storing signature content from known non-proxy websites in a database before actual detection occurs. This pre-processing step creates reference data that simplifies the real-time detection process, as the system only needs to compare against pre-established signatures rather than analyzing everything from scratch.
2Reliability
If multiple content patterns are analyzed for proxy detection, then detection reliability is improved, but processing time increases
Solution Approach 1:
The patent applies partial action by selecting and analyzing only the most relevant content patterns rather than examining every possible element of website content. The system compares website identifiers and signature content, focusing on key discriminative features that provide sufficient reliability for detection without requiring exhaustive analysis of all content elements.
Solution Approach 2:
The system uses self-service by automatically comparing website identifiers against stored signatures and making detection decisions based on pattern matching. The automated comparison process eliminates manual analysis time while maintaining reliable detection through systematic evaluation of multiple content patterns.
3Measurement precision
If website identifiers are compared against known non-proxy websites, then proxy identification accuracy is improved, but information processing requirements increase
Solution Approach 1:
The patent extracts only the essential website identifier elements needed for comparison rather than processing entire website contents. By isolating and comparing specific identifier components against stored signatures, the system achieves accurate proxy identification while minimizing the volume of data that must be processed and stored.
Solution Approach 2:
The system uses copying by storing signature representations of known non-proxy website identifiers in a database. These compact signature copies serve as reference data that can be quickly compared against encountered website identifiers, providing accurate matching without requiring the original full website content to be retained or re-processed.
