Personal Information Sharing Platform With Sunset Safe Numbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for data portability fail to adequately protect personal information, leading to privacy infringements and utility value loss, while benefiting large platforms at the expense of small businesses, and lack mechanisms for secure, controlled sharing and revenue distribution.
Innovation Solution
A system for personal-information-sharing platform service that obtains user consent, uses sunset-type safe numbers to limit information usage, and ensures secure revenue distribution, incorporating a zero trust model for database protection and auction mechanisms for personal information sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If personal information is shared by removing all personal information with metadata, then privacy protection is improved, but utility value of personal information significantly decreases
Solution Approach 1:
The patent introduces a safe number as an intermediary that mediates between the information subject and information user. Instead of directly sharing personal information or completely removing it, the safe number acts as a temporary proxy that enables controlled communication while protecting the individual's privacy. This resolves the contradiction by allowing utility (communication capability) while maintaining privacy protection.
Solution Approach 2:
The patent changes the parameter of information availability by introducing temporal limitations through sunset-type safe numbers. The safe number is valid only for a specific period and purpose, transforming personal information from a permanent state to a temporary, controlled state. This allows utility during the valid period while ensuring privacy protection after expiration.
2Object-affected harmful factors
If sunset type safe numbers are used to limit information usage period, then privacy protection is improved, but information usage flexibility is reduced
Solution Approach 1:
The patent applies dynamics by making the safe number's validity period adjustable and renewable. Rather than fixed expiration, the system allows extension of the safe number's validity based on continued consent, transforming a static limitation into a dynamic, adaptable arrangement that balances privacy protection with usage flexibility.
Solution Approach 2:
The system incorporates feedback mechanisms where information subjects can review and renew their consent for safe number usage. This feedback loop allows users to maintain control over their information while enabling continued flexible usage when desired, resolving the contradiction between privacy protection and usage flexibility.
3Productivity
If personal information is concentrated and monopolized by platform giants, then platform service capability is improved, but small and medium-sized businesses are likely to fall further into personal information famine
Solution Approach 1:
The patent segments control over personal information by enabling individual information subjects to own and manage their data through consent mechanisms. Instead of centralized monopoly, the system divides control among individuals who can selectively grant access to different information users, thereby improving both platform capability and accessibility for various sized businesses.
Solution Approach 2:
The safe number system acts as an intermediary layer that enables small and medium-sized businesses to access personal information without requiring dominance by platform giants. The safe number mechanism provides a standardized, secure interface that levels the playing field, allowing smaller entities to participate fairly in the personal information economy.
4Productivity
If personal information is shared without consent mechanisms, then information sharing efficiency is improved, but privacy infringement risks increase
Solution Approach 1:
The patent applies preliminary action by obtaining consent from information subjects before creating and distributing safe numbers. This advance authorization ensures that information sharing proceeds efficiently with pre-granted permission, eliminating the need for repeated consent requests while maintaining privacy protection through initial user approval.

AI summary
Provided is a system for providing a personal-information-sharing platform service based on a right to data portability, the system including: a user terminal configured to consent to provision of personal information for use of the personal information, input at least one type of personal information for the use of the personal information, and set a price for the at least one type of personal information; a requester terminal configured to request personal information of the user terminal and view a preset item of personal information included in the personal information within a preset information usage period; and a platform-service-providing server including a consent storage unit configured to obtain consent to provision of personal information for use of the personal information from the user terminal, a database storage unit configured to receive at least one piece of personal information from the user terminal and store the received at least one piece of personal information, an auction unit configured to, upon receiving request of the requester terminal for the at least one piece of personal information, set a budget for using the at least one piece of personal information, and a period limit unit configured to, upon the requester terminal being awarded a bid, designate an information usage period, which is a viewing restriction, for the preset item of personal information among the at least one piece of personal information, and provide the information usage period.
