Privacy Proxy for Scalable Ad Targeting Policy Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing advertising technologies face challenges in effectively targeting consumers while ensuring privacy, as current methods such as do not contact databases, opt-out programs, and the Platform for Privacy Preferences Project (P3P) are inadequate for digital media and lack scalability and reliability.
Innovation Solution
A scalable architecture for managing and enforcing user ad targeting across distributed networks, utilizing policy and profile information, with features like policy scoping, automated discovery services, and privacy-safe targeting, allowing users to define and enforce their targeting preferences without direct interaction, and providing monitoring and enforcement strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cookies are used for opt-out programs, then users can opt out of behavioral targeting, but the approach becomes unreliable due to cookie expiration, software updates, and reset
Solution Approach 1:
The patent introduces a privacy proxy as an intermediary service that sits between the user's device and the targeted advertising system. The proxy receives opt-out requests from users and translates them into actions that prevent tracking cookies from being set or interpreted by advertisers. This intermediary approach eliminates the unreliability of direct cookie-based opt-out by using a persistent proxy service that maintains user preferences across different devices and browsers.
2Adaptability or versatility
If do not contact databases are used, then consumers can be excluded from direct marketing, but the tool is crude and does not allow for fine policy-level decisions
Solution Approach 1:
The patent segments user privacy preferences into multiple policy dimensions, allowing users to make fine-grained decisions about different types of data collection and advertising. Instead of a single binary opt-out, the system divides preferences into categories such as behavioral targeting, contextual advertising, data sharing, and more. Each policy dimension can be independently configured, providing adaptability while maintaining manageable complexity through structured policy frameworks.
3Productivity
If tracking and profile building are used for targeting, then advertising effectiveness is improved, but privacy concerns are exacerbated
Solution Approach 1:
The privacy proxy acts as a mediator that enables advertising effectiveness without direct user tracking. It allows advertisers to access aggregated, anonymized consumer data and contextual information to make targeted advertising decisions while the proxy prevents direct collection and storage of personal user profiles. This intermediary layer maintains advertising productivity while eliminating the harmful privacy risks associated with direct tracking and profile building.

AI summary
A scalable architecture for managing, monitoring and enforcing user ad targeting operates across a distributed network. The architecture enables defining and enforcement of policy related to targeting across various domains, platforms, devices, protocols, interactions, content and media types. Targeting decisions utilize user policy as well as profile information. A user policy or portions thereof may be discovered and accessed without requiring direct interactions. The architecture provides a simple and extensible notion of policy scoping, provides an abstract processing model for determining actions related to interactions involving multiple policies, provides for time-limited in addition to use-limited ways to use policy and profile information, provides a set of discovery services that automate policy and profile discovery within and without the context of a targeting interaction, provides a coherent set of monitoring and enforcement strategies for policies, profiles and targeting, provides for easy integration with privacy-safe targeting, and provides scalable behavioral targeting opt-out.
