Server Device Secure Personal Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information management systems are vulnerable to data leakage as they store and transmit personal information in its raw form, making it susceptible to interception and exposure if a malicious hacker gains access to the information management server.
Innovation Solution
A server device and information management system that correlates and stores first and second character codes of different types, converting and transmitting the second character code string to a terminal device, ensuring secure data management by using an encryption method like Rijndael to generate encrypted character strings and rearranging them for secure transmission and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If personal information is stored and transmitted as raw data, then data processing is simple and fast, but security and protection against data leakage deteriorate
Solution Approach 1:
The patent applies preliminary action by encrypting personal information before storage and transmission. The server device encrypts character codes into character code strings that are then stored in the storage device and transmitted to terminal devices. This preliminary encryption ensures that even if data is intercepted or accessed unauthorizedly, the information remains unreadable, thus resolving the contradiction between processing speed and security.
Solution Approach 2:
The patent uses an intermediary approach by introducing character code strings as intermediaries between the raw personal information and the final display/output. The storage device stores encrypted character code strings, and the terminal device receives these encrypted strings and displays them as readable characters. This intermediary layer provides security while maintaining functionality.
2Reliability
If character codes are converted to encrypted character code strings, then data security is improved, but processing complexity increases
Solution Approach 1:
The patent applies copying by creating character code strings that are copies of the original character codes but transformed through encryption. The storage device stores these encrypted copies, and the terminal device uses them for display. This copying approach maintains the functionality of character display while enhancing security, as the encrypted copies cannot be directly interpreted without the proper decryption key.
3Measurement precision
If fonts are transmitted and displayed conditionally, then display accuracy is improved, but system complexity increases
Solution Approach 1:
The patent applies local quality by providing fonts selectively based on terminal device conditions. The server device transmits fonts to terminal devices that satisfy prescribed conditions (such as being authenticated or authorized). This ensures that display accuracy is maintained for authorized devices while preventing unauthorized access, balancing precision with security without unnecessarily increasing system complexity.
Data Source
AI summary
A server device for safely managing information is configured to store prescribed character codes and converted character codes in correlation with each other, said server device being connected, via a network (N), to a terminal device for receiving a converted character code string corresponding to a character string indicating personal information stored in a storage unit device. Responsive to the reception of a prescribed character code string corresponding to a character string indicating an item included in the personal information by the terminal device, the server device converts each of prescribed character codes included in the prescribed character code string to a corresponding converted character code, thereby generating a converted character code string corresponding to the character string indicating the item. The service device then commands the storage unit device to transmit the converted character code string corresponding to the character string indicating the personal information to the terminal device.
