Personalized Mobile Notifications via Segmented Privacy Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile wireless communications systems lack the ability to provide personalized notifications, such as advertisements, to users while maintaining their privacy by not disseminating personal information beyond a protected computing environment.
Innovation Solution
A communications system that includes a mobile wireless communications device, a network server within a protected computer network, and a notification server outside the protected network, where the device generates personalized notifications by filling in placeholders in generic notifications with user-specific information, and filters advertisements based on user preferences, all while maintaining privacy through a firewall module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personalized notifications are delivered to mobile users, then advertising effectiveness and user engagement are improved, but user privacy is compromised due to dissemination of personal information
Solution Approach 1:
The system segments the notification delivery process into two distinct parts: (1) a protected computing environment that stores and processes personal information without external access, and (2) an external notification server that receives only generic notifications and user preferences. This segmentation allows personalized advertising to be generated without exposing personal information to external parties.
Solution Approach 2:
The protected computing environment acts as an intermediary between the user's personal information and the external notification server. It receives generic notifications, matches them against stored user preferences and demographic data, generates personalized notifications, and sends them to the mobile device—all without the external server ever accessing personal information.
2Measurement precision
If personal information is stored and processed externally for personalized advertising, then targeting precision is improved, but security and privacy protection are worsened
Solution Approach 1:
The system performs preliminary action by pre-storing user demographic information and preferences in a protected computing environment before any advertising campaign. This allows the system to immediately match incoming generic notifications with user profiles without needing to access or transmit personal information during the advertising process.
Solution Approach 2:
The system changes the dimension of data flow by keeping personal information in a separate, protected dimensional space (the protected computing environment) while allowing generic notifications and personalized outputs to flow in the external dimension. This dimensional separation ensures personal information never leaves the secure environment.
3Object-affected harmful factors
If a protected computing environment is implemented to maintain privacy, then privacy protection is improved, but system complexity increases due to firewall and network architecture requirements
Solution Approach 1:
The system extracts the personal information processing function from the external advertising network and places it entirely within the protected computing environment. The external notification server only handles generic notifications and receives finalized personalized notifications, extracting away all complexity related to personal data management from the external system.

AI summary
A communications system may include at least one mobile wireless communications device associated with a respective user and storing personalizing information for the user, a network server within a protected computer network, and a notification server outside of the protected computer network configured to generate generic notifications. The network server may be configured to receive generic notifications from the notification server and sending the generic notifications to the at least one mobile wireless communications device. Moreover, the at least one mobile wireless communications device may be configured to receive the generic notifications from the network server and generate personalized notifications based upon the personalizing information and the received generic notifications.
