Selective Anonymous Proxy for Cookie Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern web browsers' cookie management settings often inadvertently disable desirable website functions, such as Google's search and mail services, due to their restrictive security settings that block all cookies from specific domains, leading to interference with user experiences.
Innovation Solution
Implementing a method and apparatus that selectively uses an anonymous proxy to filter out user identifying information from requests based on context criteria, allowing user requests to be forwarded to the proxy only when specific conditions are met, thereby preserving functionality while maintaining privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all cookies are blocked from specific domains to maintain security, then user privacy is improved, but desirable website functions become disabled
Solution Approach 1:
The patent applies local quality by differentiating cookie handling on a per-domain basis rather than applying a blanket block. The system identifies specific domains that require anonymous access and applies cookie blocking only to those domains, while allowing cookies from other domains to function normally. This resolves the contradiction by making the security measure localized rather than universal, preserving website functions that depend on cookies while maintaining privacy where needed.
Solution Approach 2:
The patent implements dynamics by making the cookie blocking behavior adaptive rather than static. The system dynamically determines whether to block cookies based on the target domain and context, switching between blocking and allowing cookies as needed. This dynamic approach allows the security setting to adapt to different website requirements, preventing the degradation of website functionality while maintaining security where appropriate.
2Loss of information
If user identifying information is filtered out from requests, then privacy is improved, but website functionality may be interfered with
Solution Approach 1:
The patent applies segmentation by dividing user identifying information into different categories and applying different filtering rules to each category. Instead of blocking all identifying information universally, the system segments cookies by domain and filters only those from domains designated for anonymous access. This segmentation allows the system to protect privacy for specific services while preserving functionality for others that require user identification.
Solution Approach 2:
The patent introduces an intermediary mechanism (the anonymous proxy system) that mediates between the user's privacy needs and website functionality requirements. The proxy intercepts requests, determines whether cookie blocking is appropriate based on domain context, and selectively filters or allows cookies accordingly. This intermediary layer resolves the contradiction by providing intelligent mediation rather than direct blocking, maintaining both privacy and functionality.
3Object-affected harmful factors
If a security setting blocks all cookies from a domain, then privacy against tracking is improved, but legitimate services like Gmail and search become unusable
Solution Approach 1:
The patent applies local quality by implementing domain-specific cookie policies rather than universal blocking. The system identifies that certain domains (like gmail.com and search services) require cookies for functionality and creates exceptions for those domains while maintaining blocking for other domains used for tracking. This localized approach eliminates harmful tracking while preserving legitimate services.
Solution Approach 2:
The patent converts the potential harm of cookie blocking into a benefit by using the same mechanism to protect privacy while intentionally preserving functionality for trusted services. The system transforms the blanket blocking approach into a selective approach where cookies are blocked only where they serve tracking purposes, while being allowed for services that require them for operation. This converts the harmful effect into a beneficial privacy protection that doesn't sacrifice usability.
Data Source
AI summary
A method and computer system for selectively using an anonymous proxy. A user request for content is received. A determination is made as to whether the user request satisfies context criteria. When the user request satisfies the context criteria, the user request is forwarded to an anonymous proxy. When the user request does not satisfy the context criteria, the request is sent directly to a content provider.
