Advertisement Gateway Mediating Device Identity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face profiling issues when handling advertisements, as advertisement providers can track and misuse device information, leading to loss of control over selected advertisements by communication service providers.
Innovation Solution
An advertisement gateway system is established to mediate communications between electronic devices and advertisement/content servers, filtering identifying information and rewriting requests to route all communications through the gateway, ensuring that identifying information is not directly sent to external servers, and using secure cryptographic hash functions to create temporary identities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If advertisement content directly references external source addresses, then advertisement functionality is maintained, but device identifying information is exposed to external servers enabling profiling
Solution Approach 1:
The patent introduces an advertisement gateway as an intermediary component that sits between the electronic device and external advertisement servers. The gateway rewrites outbound requests from advertisement content to route through its own address, and strips identifying information before forwarding requests to external sources. This mediator approach maintains advertisement functionality while protecting device identity from exposure to external servers.
2Object-affected harmful factors
If advertisement gateway rewrites all outbound requests, then device identity is protected, but request routing complexity increases
Solution Approach 1:
The patent implements preliminary action by having the advertisement gateway pre-rewrite all outbound requests in advertisement content to point to the gateway's own address before the content is executed on the electronic device. This advance modification ensures that all subsequent requests automatically route through the gateway without requiring real-time interception or complex runtime rewriting logic, thereby reducing routing complexity while maintaining identity protection.
3Object-affected harmful factors
If identifying information is removed from requests, then profiling is prevented, but request accuracy for content delivery may be compromised
Solution Approach 1:
The patent applies the extraction principle by selectively removing only the identifying information portions from outbound requests while preserving the essential request parameters needed for accurate content delivery. The advertisement gateway extracts and strips device-specific identifying fields from requests before forwarding them to external advertisement servers, thereby preventing profiling while maintaining sufficient request accuracy for proper content retrieval and delivery.

AI summary
A method of routing advertisement based content requests through an advertisement gateway comprises receiving, on an electronic device, an advertisement content, rendering the advertisement content in a test environment, intercepting at least one outbound request for secondary content initiated by the execution of the advertisement content, where the outbound request is directed to an external source address other than an advertisement gateway, rewriting the advertisement content to direct the outbound request to the advertisement gateway address, creating a revised advertisement content based on the rewriting, and executing the revised advertisement content on the electronic device.
