Encrypted Publisher Cookie Linking for Cross-Domain Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to deliver customized content effectively to user devices when browsers are configured to block third-party cookies, limiting the ability of content management systems to recognize user devices and provide relevant content.
Innovation Solution
A method that uses encrypted publisher cookies and creates a content serving system cookie, linking them in a data structure to enable content delivery even when third-party cookies are blocked, allowing for user interaction data to be linked across different publisher pages and domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If third-party cookies are used to track user devices across different publisher pages, then customized content delivery is improved, but browser security settings blocking third-party cookies worsen the ability to recognize user devices
Solution Approach 1:
The patent introduces encrypted publisher cookies as an intermediary mechanism that enables cross-page user recognition without relying on traditional third-party cookies. These encrypted cookies are set by the content serving system and returned with subsequent content requests, allowing the system to identify and deliver customized content to returning users even when third-party cookie blocking is enabled
Solution Approach 2:
The patent transforms the cookie parameter by encrypting publisher-specific cookies before they are set in the user's browser. This encryption modifies the cookie's properties so that while it maintains its functional purpose of user identification, it appears as a first-party cookie to browser security mechanisms, thereby bypassing third-party cookie blocking while still enabling customized content delivery
2Object-affected harmful factors
If encrypted publisher cookies are used instead of third-party cookies, then user privacy is improved, but the complexity of cookie management and linking increases
Solution Approach 1:
The patent creates a simplified copy or representation of the user identification process through encrypted cookies. Instead of managing complex third-party cookie infrastructure, the system uses encrypted versions of publisher cookies that follow the same functional pattern but with enhanced privacy properties, reducing the complexity burden while maintaining privacy benefits
3Measurement precision
If content serving system cookies are created and linked with encrypted publisher cookies, then content customization accuracy is improved, but data structure complexity increases
Solution Approach 1:
The patent segments the cookie management system into distinct components: encrypted publisher cookies for user identification, content serving system cookies for tracking content interactions, and a data structure for linking them. This segmentation allows each component to have a specific, simplified function while the overall system achieves high customization accuracy through their coordinated operation

AI summary
Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for providing content. A method includes: receiving a first request for filling a slot on a first publisher page, the request including an encrypted publisher cookie; providing content responsive to the request; upon receipt of an indication that a user interacted with the content, creating and providing a content serving system cookie; linking the received encrypted publisher cookie with the content serving system cookie; receiving a second, different request for content in association with rendering a second, different publisher page, the second, different request including an encrypted publisher cookie associated with the second different publisher page and the previously provided content serving system cookie; linking the received encrypted publisher cookie associated with the second, different publisher page with the encrypted publisher cookie associated with the first publisher page; and using the linkings to determine content to deliver.
