Unique Identification Header for Privacy-Preserving Content Targeting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content providers face challenges in delivering targeted services and content to user devices due to security restrictions that prevent access to user information, limiting their ability to provide personalized content without compromising user identity.
Innovation Solution
A system that uses a unique identification header (UIDH) associated with a user device to allow content providers to determine demographic and subscription information without accessing identity information, by embedding the UIDH in a test message and generating a token that can be used to provide targeted content without revealing user identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content providers access user information to provide targeted services, then service personalization is improved, but user security and identity protection deteriorate
Solution Approach 1:
The patent introduces a service provider network as an intermediary between content providers and user devices. This intermediary enables targeted content delivery by processing requests and matching users with relevant content without allowing content providers to directly access user identity information, thus resolving the contradiction between personalization and security
Solution Approach 2:
The system segments information access by creating distinct layers: user identity information is separated from content delivery processes. The service provider network handles identity verification and content matching in separate operations, allowing targeted services while preventing direct access to sensitive user data by content providers
2Object-affected harmful factors
If content providers are restricted from accessing user information for security reasons, then user identity protection is improved, but ability to provide targeted content deteriorates
Solution Approach 1:
The service provider network acts as a mediator that receives content requests, processes them against user profiles, and delivers targeted content without requiring content providers to access user information directly. This maintains security restrictions while enabling effective targeted content delivery through the intermediary's processing capabilities
3Adaptability or versatility
If unique identifiers are implemented to enable targeted content delivery, then content personalization capability is improved, but system complexity increases
Solution Approach 1:
The service provider network performs multiple functions using a single system infrastructure: it handles user authentication, content request processing, targeted content delivery, and security management. This multi-functionality enables content personalization capabilities while avoiding the need for separate complex systems for each function

AI summary
A user device may receive a request for content; provide the request to a first server; receive an instruction based on providing the request for content; and provide a message to a second server based on receiving the instruction. The message may cause the second server to embed a unique identifier (ID) of the user device in the message to form a modified message for transmission to a third server. The modified message may cause the third server to form an object having the unique ID. The user device may receive the object based on providing the message to the second server; provide the object to the first server or to a fourth server; and receive, from the first server or the fourth server, particular content based on providing the object to the first server or the fourth server. The particular content may be based on the unique ID.
