User Information Storage Control via Desensitization and Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user information storage control technologies face challenges with low data storage security and high storage capacity, requiring users to repeatedly input the same information across multiple applications, leading to inefficiency and increased risk of data leakage.
Innovation Solution
A user information storage control method that standardizes user data, extracts information using a multi-modal information collection model, performs data desensitization, divides non-sensitive fields into regularized and irregularized information, and stores them in separate mapping tables, ensuring secure and efficient storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If user information is stored in original format on server, then storage capacity is high, but data storage security is low
Solution Approach 1:
The patent extracts sensitive information from original user data and stores it separately in a desensitized form. The mapping relationship between original data and desensitized data is stored in a mapping table, allowing retrieval without storing the actual sensitive information in plaintext on the server.
Solution Approach 2:
The patent introduces a mapping table as an intermediary between original user information and stored data. This mapping table contains mapping relationships that enable data retrieval without directly storing sensitive information, thus improving security while maintaining storage functionality.
2Reliability
If same user information is required in multiple applications, then user identity validation is complete, but repeated input operations increase and efficiency decreases
Solution Approach 1:
The patent creates a unified user information management system that serves multiple applications simultaneously. User information is standardized and stored once, then can be retrieved and used across different applications through the mapping mechanism, eliminating the need for repeated input while maintaining validation capability.
Solution Approach 2:
The patent performs preliminary standardization and storage of user information in a unified format. Before users need to provide information to multiple applications, the information is already captured, standardized, and stored with mapping relationships established, so subsequent applications can retrieve the data without requiring re-input.
3Reliability
If user information is standardized and desensitized, then data storage security is improved, but information processing complexity increases
Solution Approach 1:
The patent segments the user information processing into distinct components: standardization processing, desensitization processing, and mapping relationship management. Each component handles a specific aspect of the data transformation, making the overall complex process more manageable and systematic.
