Color-Based Encryption for Secure Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information management systems lack unified and standardized methods for preventing information leakage, invasion, alteration, and tampering across various devices and platforms, particularly in managing embedded software and systems, leading to security breaches and data loss.
Innovation Solution
An information management system that employs color-based encryption using ONC correspondence tables and conversion functions to encrypt and decrypt files, ensuring secure storage and access control, while preventing unauthorized access and data leakage by using a computer identification number and external recording device identification for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption is applied to files and data, then information security is improved, but information management complexity increases
Solution Approach 1:
The patent introduces an information management file as an intermediary component that mediates between the encryption system and the user. This file contains control information, conversion tables, and management data that enable automated handling of encrypted files without requiring users to understand encryption mechanisms, thus resolving the contradiction between security and management complexity
Solution Approach 2:
The encryption system is designed to automatically manage encrypted files through self-service mechanisms. The system automatically converts encrypted files to editable formats when needed, manages conversion tables, and handles decryption/encryption operations without user intervention, reducing management complexity while maintaining security
2Productivity
If unified information management is implemented across organizations, then management efficiency is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal information management system that can handle multiple types of files (documents, drawings, executables, images, video, audio) and operate across different computers and devices. The system uses standardized conversion tables and information management files that work universally across the organization, improving management efficiency without proportionally increasing complexity
Solution Approach 2:
The system manages complexity by changing parameters such as using conversion tables with different granularities (ON correspondence, NC correspondence, CO correspondence) and adapting encryption levels based on file types and organizational requirements, allowing efficient unified management with controlled complexity
3Adaptability or versatility
If color-based encryption is used, then encryption versatility is improved, but processing complexity increases
Solution Approach 1:
The patent segments the encryption process into distinct conversion stages using multiple correspondence tables (ON correspondence table, NC correspondence table, CO correspondence table). Each table handles a specific aspect of the color-based encryption, allowing versatile encryption across different file types while managing processing complexity through modular, segmented processing steps
Data Source
AI summary
An information management system provided with an encrypting means for encrypting an original file to prepare an encrypted file, a data storage memory which stores the encrypted file, a decrypting means, a general memory, an information managing means for decrypting the encrypted file to an editable display file etc. and storing it in the general memory in a regular operational processing cycle, performing the required editing in the form of the display file etc., converting the display file etc. after editing to an encrypted file by the encrypting means, and storing this in the data storage memory, and an information management file which controls processing of or operations on the encrypted file by the information managing means. This standardizes information management at the different levels of an organization, managers, etc., enables secure protection and management of information contained in the different machinery and equipment, lightens the load of information management, prevents leakage of information, and preserves and protects files and prevents their destruction, tampering, and alteration.
