Selective Personal Information Codes for Privacy-Limited Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal information systems risk providing unnecessary personal information to service providers, posing a security risk.
Innovation Solution
A personal information providing system with first and second information terminals that allow users to select and display only necessary personal information, using color-coded information codes and communication with a server to manage and control the provision of personal data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of personal information are included in the information code, then the information code can provide comprehensive personal information for various services, but unnecessary personal information may be provided to service providers
Solution Approach 1:
The information code is segmented to include multiple types of personal information (e.g., name, address, health insurance card number, driver's license number) that can be independently selected and provided based on the specific service requirements. This allows the system to maintain comprehensive information capability while enabling selective disclosure to avoid unnecessary information provision.
Solution Approach 2:
The system dynamically adjusts the personal information provided in the information code based on the service type and user selection. The information code can be configured to include different combinations of personal information depending on the service context, making the information provision adaptive rather than static.
2Loss of information
If all personal information is provided in the information code, then the service provider can access complete user data, but user privacy and security are compromised
Solution Approach 1:
The system extracts only the necessary personal information required for a specific service from the complete set of user personal information and includes it in the information code. This extraction process ensures that sensitive information not required for the service (e.g., health insurance card number for car rental) is not provided, thereby maintaining user privacy and security while still providing complete data access when needed.
3Productivity
If the information code contains service-specific personal information, then the service can be provided efficiently, but the information code must be customized for each service
Solution Approach 1:
The information code is designed with universal functionality to support multiple service types. By incorporating multiple types of personal information (name, address, health insurance card number, driver's license number, etc.) in a single information code structure, the system can serve different services (medical, transportation, rental, etc.) without requiring separate customization for each service, thereby maintaining efficiency while reducing complexity.

AI summary
[Problem] Provided is a personal information providing system, a program, and a recording medium that effectively avoid the provision of personal information that is not necessary for a service used by a user to a service provider. [Solution] A personal information providing system includes a first information terminal 10 and a second information terminal 20 different from the first information terminal 10 and provides the second information terminal 20 with personal information of a user of the first information terminal 10. The first information terminal 10 includes a presentation means 15 that presents a first information code 41 containing two or more pieces of personal information. The first information terminal 10 or the second information terminal 20 includes a setting means 15 or 25 that sets personal information permitted for provision by a user from among the two or more pieces of personal information contained in the first information code 41. The second information terminal 20 includes a display control means 25 that displays only the personal information permitted for provision among the two or more pieces of personal information contained in the first information code 41 presented by the first information terminal 10.
