Cross-Device Ad Targeting via IP Address Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in collecting and associating user behavior across multiple devices, especially when users do not log in, which hinders targeted advertisement distribution.
Innovation Solution
An information processing system that acquires and associates IP addresses and advertisement IDs to identify user devices, allowing for targeted advertisement distribution by linking television viewing logs with device-specific data, even when users access multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user information is associated based on login information, then targeted advertising can be provided to logged-in users, but user behavior cannot be collected from devices where the user does not log in
Solution Approach 1:
The patent introduces IP address as an intermediary element to associate television viewing logs with advertisement IDs. Instead of relying solely on login information, the system uses IP addresses as a common denominator to link different devices (TV and mobile device) to the same user, enabling cross-device behavior tracking without requiring login on each device.
2Adaptability or versatility
If multiple devices are used by the same user, then device coverage increases, but difficulty in associating devices increases
Solution Approach 1:
The patent uses IP address as a mediator to simplify the association process across multiple devices. By matching IP addresses from television viewing logs and mobile device advertisement data, the system can automatically link devices to users without complex authentication or manual association processes.
Solution Approach 2:
The patent applies a universal association method that works across different device types (TV, mobile, tablet) by relying on the common IP address identifier. This universal approach eliminates the need for device-specific association mechanisms and can be applied uniformly to any device connected to the network.
3Measurement precision
If only logged-in user data is used, then data accuracy is maintained, but productivity of advertisement distribution decreases
Solution Approach 1:
The patent uses IP address as a partial identifier that can identify users even when complete login information is unavailable. While IP address alone may not provide full user authentication, it serves as sufficient partial information to enable advertisement distribution to a broader audience, accepting some reduction in identification precision to gain significant productivity improvement.

AI summary
To implement advertisement distribution suitable for a user by associating each device even when a user uses a plurality of devices, the information processing apparatus includes: an acquiring unit configured to acquire first identification information at least including an Internet Protocol (IP) address and information regarding a television viewing log, and second identification information at least including an IP address and an advertisement ID (Identifier); and a control unit configured to perform control to identify a combination of the viewing log and the advertisement ID corresponding to the same IP address on the basis of the first identification information and the second identification information.
