Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal information management systems face issues with data security and low utilization of user information due to exposure to hacking risks and outdated data storage, limiting effective utilization of personal information.
Innovation Solution
A personal information management server that manages user data through a user terminal, utilizing a communication circuit, memory, and processor to collect and generate target information for predicting events by determining relevant properties and transmitting only necessary personal information, secured by smart contracts on a blockchain network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a service provider stores and uses personal information of a user, then the personal information can be utilized for service provision, but the personal information is exposed to hacking danger and has low utilization due to outdated data
Solution Approach 1:
The patent introduces a smart contract on the blockchain network as an intermediary between the user terminal and the service provider. The smart contract acts as a mediator that enables secure data sharing by storing only necessary personal information on the blockchain while keeping comprehensive data at the user terminal, thus improving utilization while maintaining security through the intermediary mechanism
Solution Approach 2:
The patent extracts only the necessary personal information required for service provision and stores it on the blockchain network via smart contract, while leaving the remaining personal information at the user terminal. This extraction approach enables service providers to access and utilize relevant data without exposing the user's complete personal information, thereby improving data utilization while maintaining security
2Loss of information
If all personal information of a user is collected and stored, then complete data is available for analysis, but the danger of information exposure increases significantly
Solution Approach 1:
The patent extracts and stores only the specific personal information necessary for service provision on the blockchain network, while retaining the complete set of personal information at the user terminal. This selective extraction ensures that service providers receive adequate data for their needs without the increased security risks associated with storing comprehensive personal information centrally
Solution Approach 2:
The patent segments personal information into two parts: necessary information stored on the blockchain network via smart contract for service provision, and remaining information kept at the user terminal. This segmentation reduces information exposure risk by ensuring that only essential data is stored externally, while maintaining data completeness for service analysis purposes
3Ease of operation
If personal information is stored by a provider, then the information is readily accessible, but the data becomes outdated and utilization decreases
Solution Approach 1:
The smart contract on the blockchain network serves as an intermediary that enables real-time or near-real-time data updates from the user terminal to the service provider. This intermediary mechanism maintains data accessibility while ensuring that the information remains current, thereby improving utilization without sacrificing ease of access

AI summary
A personal information management server comprises: a communication circuit configured to transmit/receive data to/from an external device; memory configured to store data required for operating the management server; and a processor configured to perform a plurality of operations in response to the execution of instructions stored in the memory. The plurality of operations performed by the processor include: receiving target event information from a request terminal; determining a target property associated with a target event among properties of the personal information; transmitting a personal information collection request for collecting the personal information corresponding to the target property from a user terminal; receiving the personal information corresponding to the target property from the user terminal; generating target information for predicting the occurrence of the target event by using the personal information corresponding to the target property; and transmitting the determined target information to the request terminal.
