Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing personal information when subscribing to services often result in outdated information, accuracy issues, legal burdens, and discrepancies in de-identification levels, leading to inefficiencies and discomfort for users.
Innovation Solution
An electronic device equipped with a processor that generates a smart contract for personal information transactions on a blockchain, including information categories, external users, and de-identification levels, allowing for real-time updates and secure management of personal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an enterprise collects and stores personal information when a person subscribes to a service, then the enterprise can manage and use the personal information, but the personal information may become outdated and lose real-time properties
Solution Approach 1:
The patent inverts the traditional centralized storage model by enabling distributed storage across multiple electronic devices. Each device stores copies of personal information, allowing any device to provide updated information without relying on a central enterprise database. This inversion resolves the contradiction by eliminating the single point of obsolescence.
Solution Approach 2:
The patent implements a feedback mechanism where electronic devices automatically update personal information and notify other devices in the network. When information changes on one device, the system propagates these updates to maintain consistency across all devices, ensuring real-time accuracy without centralized control.
2Adaptability or versatility
If an enterprise collects and stores personal information, then the enterprise can provide services using the information, but legal burdens occur in storing the personal information
Solution Approach 1:
The patent extracts the storage and management responsibility of personal information from the enterprise and relocates it to the user's electronic devices. The enterprise only accesses information when needed for service provision, rather than continuously storing it. This extraction eliminates the legal burden of storage while preserving service capabilities.
Solution Approach 2:
The patent introduces smart contracts as intermediaries between the enterprise and user data. These contracts automatically manage information sharing permissions, access control, and compliance requirements, reducing the enterprise's direct legal liability while enabling service provision through automated enforcement of privacy rules.
3Ease of manufacture
If an enterprise collectively sets the de-identification level of personal information, then the enterprise can standardize data management, but there may occur a difference between the de-identification level set by the enterprise and the level recognized by the person
Solution Approach 1:
The patent transforms the static, enterprise-determined de-identification level into a dynamic parameter that users can adjust according to their preferences. Each user can set different de-identification levels for different devices or contexts, allowing the system to adapt to individual needs while maintaining standardized management through automated enforcement of user choices.
4Ease of operation
If a person directly provides, changes, or deletes personal information, then the person has control over their data, but discomfort occurs in the process
Solution Approach 1:
The patent implements self-service automation where electronic devices automatically manage personal information updates across the network without requiring direct user intervention. When information changes on one device, the system autonomously propagates updates to other devices, providing user control while eliminating the time-consuming manual management process.
