Browser Ad Interceptor for Unauthorized Content Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer systems lack effective mechanisms to detect and mitigate unauthorized, illegal, or unethical advertisements, which can deceive users and compromise their security during web browsing, especially as these advertisements often evade legal remedies due to international jurisdiction issues.
Innovation Solution
A system that intercepts data sent to a browser, analyzes advertisements for unauthorized content, and displays warning messages or suppresses them based on predefined heuristics, using a database of cached heuristics to identify and categorize advertisements as unauthorized, with actions ranging from muting to blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ad blockers are used to block all advertisements, then users are protected from unauthorized advertisements, but legitimate advertisements are also blocked and content providers may prevent users from receiving content
Solution Approach 1:
The patent applies local quality by differentiating between authorized and unauthorized advertisements through analysis of specific characteristics such as domain reputation, content patterns, and advertiser verification. Instead of treating all advertisements uniformly, the system applies different quality standards and filtering rules to different types of advertisements, allowing legitimate ads to pass through while blocking malicious ones.
Solution Approach 2:
The system performs preliminary analysis of advertisements before they are displayed to users. By pre-establishing criteria for authorized advertisers and pre-analyzing advertisement content against these criteria, the system makes decisions about which advertisements to allow or block before user exposure, thus preventing the need for reactive ad blocking that would affect all advertisements equally.
2Object-affected harmful factors
If all advertisements are blocked to prevent unauthorized content, then user security is improved, but users lose access to legitimate advertising-supported content
Solution Approach 1:
The patent introduces an intermediary analysis system that sits between the advertisement source and the user. This intermediary component analyzes advertisement content, verifies advertiser authorization, and makes intelligent decisions about which advertisements to allow or block. This mediator approach prevents harmful advertisements while preserving access to legitimate content, avoiding the extreme of blocking all advertisements.
3Measurement precision
If advertisement analysis is performed to detect unauthorized content, then detection accuracy is improved, but system complexity and processing time increase
Solution Approach 1:
The patent segments the advertisement analysis process into multiple independent components: content analysis, domain verification, reputation checking, and pattern recognition. Each component handles a specific aspect of detection, allowing the system to achieve high accuracy through specialized sub-tasks rather than a single complex analysis mechanism. This modular approach manages system complexity by dividing the overall detection function.
Solution Approach 2:
The system applies partial analysis to all advertisements and excessive (detailed) analysis only to suspicious cases. By using a two-stage approach where basic filtering is applied universally and comprehensive analysis is reserved for borderline cases, the system achieves high detection accuracy without requiring full complex analysis for every advertisement, thus balancing precision with computational efficiency.
Data Source
AI summary
A method of protecting a device from unauthorized advertisements includes intercepting data from the Internet that is to be displayed by a browser and determining if the data includes an advertisement. If the data includes an advertisement, the advertisement is analyzed to determine if the advertisement is an unauthorized advertisement and if the advertisement is an unauthorized advertisement, a warning message is displayed.
