Attribute Information Segmentation for Secure Cross-Region Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of user registration information across different regions is hindered by network issues and the risk of indiscriminate diffusion of personal information, particularly attribute information that should not be widely shared.
Innovation Solution
An information processing device generates incomplete and complementary attribute information, transmitting only the minimum necessary information for login and requesting complementary attribute information on demand to ensure secure and controlled data exchange between regional servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user registration information is transmitted in advance to multiple servers, then user convenience is improved by avoiding re-registration, but information security deteriorates due to indiscriminate diffusion of personal information
Solution Approach 1:
The attribute information is segmented into incomplete attribute information (transmitted to multiple servers) and complementary attribute information (transmitted only when needed). This segmentation allows user registration to be completed across multiple servers without transmitting complete personal information indiscriminately, thus improving user convenience while maintaining information security.
Solution Approach 2:
Incomplete attribute information is transmitted to multiple servers in advance during the initial registration process, allowing users to conveniently access services without re-registration. The complementary attribute information is withheld and only transmitted when actually needed, preventing premature diffusion of complete personal information.
2Loss of information
If complete attribute information is transmitted to another server, then data completeness is improved for service functionality, but information security deteriorates due to potential data leakage
Solution Approach 1:
Attribute information is divided into incomplete and complementary portions. The incomplete attribute information is transmitted to the other server to enable basic service functionality, while the complementary attribute information is transmitted only when absolutely necessary, thus maintaining data completeness for service operation while minimizing data leakage risk.
Solution Approach 2:
Instead of transmitting complete attribute information, only the minimum necessary incomplete attribute information is transmitted initially. This partial transmission is sufficient for service functionality while reducing the risk of data leakage. Complete information is transmitted only when absolutely necessary.
3Adaptability or versatility
If user registration information is transmitted across networks, then service accessibility is improved for users in different regions, but transmission reliability deteriorates due to network issues
Solution Approach 1:
Incomplete attribute information is transmitted to the other server in advance during initial registration, ensuring service accessibility for users in different regions. This preliminary transmission of essential information ensures that even if subsequent transmissions of complementary information fail due to network issues, the basic service functionality remains available.
4Object-affected harmful factors
If attribute information is transmitted as incomplete data, then information security is improved by preventing indiscriminate diffusion, but data utility deteriorates until completion
Solution Approach 1:
Attribute information is segmented into incomplete and complementary portions. The incomplete attribute information provides sufficient utility for basic service operation while maintaining information security by preventing indiscriminate diffusion of complete personal information. The complementary information is added only when needed to restore full data utility.

AI summary
The information processing device includes a registration information obtaining unit, a data generating unit and a transmission processing unit. The registration information obtaining unit obtains user identification information, a login password, and attribute information in association with one another as user registration information. The data generating unit generates incomplete attribute information and complementary attribute information such that the attribute information can be reconstructed by combining the incomplete attribute information and the complementary attribute information with each other. The transmission processing unit transmits the user identification information, the login password, the incomplete attribute information, and the complementary attribute information to another information processing device. The transmission processing unit transmits the user identification information, the login password, and the incomplete attribute information to the another information processing device, and the transmission processing unit transmits the complementary attribute information in response to a request from the another information processing device.
