Targeted Advertisement Delivery via Anonymized Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile advertisement services often provide advertisements to unspecified individuals, leading to reduced effectiveness and increased user dissatisfaction, as they do not account for personal preferences or demographics, and there is a growing concern about indiscriminate personal information collection.
Innovation Solution
A method that extracts a list of targeted customers based on authentication information and collects non-authentication based information, such as app activity and user identification data, to provide targeted advertisements without personal information collection, using a service device and user terminal application to check advertisement conditions and deliver relevant content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personal information is collected for targeted advertising, then advertisement effectiveness is improved, but user privacy protection deteriorates
Solution Approach 1:
The patent extracts only the necessary non-personal information (device identifiers, app activity data, communication module information) from the user terminal to enable targeted advertising without extracting actual personal information. This separation allows advertising effectiveness to be maintained while protecting user privacy by leaving personal information in the terminal and only transmitting anonymized data to the server.
Solution Approach 2:
The patent introduces an intermediary mechanism where the user terminal acts as a mediator between the advertising system and personal information. The terminal collects non-personal information locally and transmits only this anonymized data to the server, preventing direct exposure of personal information while still enabling targeted advertising through the intermediary's selective information sharing.
2Measurement precision
If non-authentication based information is collected, then advertisement targeting accuracy is improved, but information collection complexity increases
Solution Approach 1:
The patent implements self-service by enabling the user terminal to automatically collect non-authentication based information (device identifiers, app activity information, communication module information) without requiring manual user input or complex external verification systems. The terminal autonomously gathers this data from its own operational state, simplifying the overall information collection process while maintaining targeting accuracy.
3Measurement precision
If authentication based information is used for customer list extraction, then customer targeting precision is improved, but user authentication requirements increase
Solution Approach 1:
The patent applies partial action by using only non-authentication based information for the advertising targeting process, rather than requiring full authentication. This partial use of information (device identifiers, app activity data without user login) achieves sufficient targeting precision for advertising purposes while avoiding the excessive requirement of complete user authentication, thus maintaining ease of operation.

AI summary
The present invention relates to a method and device for providing an advertisement, in which a service device extracts a list of customers to be targeted based on authentication based information, and a user terminal device corresponding to the extracted list of customers collects non-authentication based information to provide an advertisement to an advertisement target application operated by a third party, and a recording medium in which a computer program for performing the method is recorded.
