Edge Communication Scrubbing for Privacy-Safe Mobile Ad Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems face challenges in ensuring the security and confidentiality of user private information while delivering commercial communications to mobile devices, particularly when users roam to different access providers, and there is a need for proactive scrubbing to prevent unintentional sharing of consent data and optimize communication delivery based on user preferences.
Innovation Solution
Implementing an edge device that receives a scrubbed token list and a telephone number list, determines the presence of a mobile device in a specific area, and communicates with an originating access provider to deliver commercial communications only if the device's number matches a scrubbed token list, ensuring user preferences are respected and consent data is not leaked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user private information is shared with edge devices for commercial communication delivery, then communication delivery accuracy is improved, but user data security and confidentiality deteriorate
Solution Approach 1:
The patent extracts only the necessary identifying information (telephone numbers) from user data, removing all other personal identifiers and private information. The edge device receives a scrubbed token list containing only telephone numbers needed for delivery verification, while the originating access provider holds the complete user profile data. This extraction approach enables delivery accuracy while minimizing data exposure.
Solution Approach 2:
The patent introduces an intermediary data structure (scrubbed token list) that mediates between the edge device and user private information. This intermediary contains only the minimum necessary data (telephone numbers) for delivery verification, acting as a buffer that prevents direct access to complete user profiles while still enabling accurate communication delivery.
2Productivity
If complete user data is provided to edge devices, then communication routing optimization is improved, but data confidentiality deteriorates
Solution Approach 1:
The patent extracts only the routing-critical element (telephone number) from complete user data for provision to the edge device. The scrubbed token list contains exclusively telephone numbers needed for routing decisions, excluding all other confidential user information such as personal identifiers, communication history, and preferences. This enables routing optimization while preserving data confidentiality.
3Productivity
If telephone numbers are exposed to edge devices, then commercial communication delivery is improved, but unintentional sharing of consent data occurs
Solution Approach 1:
The patent extracts only telephone numbers from complete user data for inclusion in the scrubbed token list provided to the edge device. By removing all consent-related information and other sensitive data, the system enables commercial communication delivery verification while preventing unintentional sharing of consent data. The edge device can verify delivery against telephone numbers without accessing any consent information.

AI summary
An edge device can receive a commercial communication, a scrubbed token list and a telephone number list. Responsive to determining the mobile device is detected in the specific area, whether a telephone number of the mobile device is contained in the telephone number list can be determined. Responsive to determining that the telephone number of the mobile device is contained in the telephone number list, the telephone number of the mobile device, the scrubbed token list and the commercial communication can be communicated to an originating access provider, wherein the originating access provider communicates to the mobile device the commercial communication based, at least in part, upon whether the telephone number of the mobile device matches a token contained in the scrubbed token list.
