Mobile Device User Profile Generation for Privacy-Safe Targeted Ads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile targeted-content-message systems face challenges in delivering effective targeted advertising due to privacy regulations, such as the Graham-Leach-Bliley Act and European Union data protection policies, which restrict the use of personal information for marketing purposes, limiting the ability to deliver relevant advertisements to wireless communication devices without compromising user privacy.
Innovation Solution
A method and system that enables wireless access terminals to generate user profiles locally, using on-board processing to characterize user behavior and preferences, thereby selecting and receiving targeted content messages at optimal times without exposing sensitive information, employing techniques like one-way hash functions and proxy servers for anonymization and secure data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personal information is collected and used for targeted advertising, then advertising effectiveness and user relevance are improved, but user privacy and compliance with regulations deteriorate
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the advertising network. The device generates local user profiles using on-board processing and one-way hash functions, acting as a mediator that enables targeted advertising while protecting user privacy by never transmitting raw personal information to external servers.
Solution Approach 2:
The patent replaces the traditional server-side profile generation system with client-side on-board processing. Instead of mechanically collecting and transmitting personal data to centralized servers, the system uses distributed processing on mobile devices with cryptographic hash functions to generate advertising identifiers locally, eliminating the need for centralized personal data storage.
2Adaptability or versatility
If user profiles are generated and stored on external servers, then targeted advertising capability is improved, but data security and user control deteriorate
Solution Approach 1:
The patent segments the profile generation process into local on-board processing on the mobile device and minimal verification on external servers. User profile data is segmented into local hashed identifiers that can be verified externally without exposing raw personal information, enabling targeted advertising while maintaining data security through distributed architecture.
Solution Approach 2:
The mobile device performs self-service by generating its own user profile locally using on-board processing and one-way hash functions. The device autonomously creates advertising identifiers from user information without requiring external server intervention for profile creation, thereby maintaining user control and data security while enabling targeted advertising capabilities.
3Measurement precision
If personal information is transmitted to advertising networks, then advertising targeting precision is improved, but compliance with privacy regulations deteriorate
Solution Approach 1:
The patent substitutes the mechanical transmission of personal information with cryptographic one-way hash functions. Instead of transmitting readable personal data to advertising networks, the system transmits hashed identifiers that preserve targeting precision while making the data computationally infeasible to reverse-engineer, ensuring compliance with privacy regulations like GLBA and EU data protection policies.
Solution Approach 2:
The patent changes the parameter of data representation from raw personal information to one-way hashed identifiers. This parameter transformation maintains the uniqueness and targeting precision of user profiles while fundamentally altering the data format to comply with privacy regulations, as the hashed data cannot be used to reconstruct original personal information.
