Dual-Mode Data Terminal with Lock System Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data processing devices lack effective security measures to prevent malicious viruses from compromising user data, especially when accessing unfamiliar websites or downloading applications, leading to potential data loss and privacy breaches.
Innovation Solution
Implementing a dual-mode operation system with a lock mode for secure data protection and an unlock mode for reliable data processing, along with physical or operational isolation between the main and lock systems, and a mode-switching input unit for seamless transitions without turning the display off and on.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a data processing terminal allows users to access unfamiliar websites or download applications, then user convenience and productivity are improved, but security and data integrity deteriorate due to potential malicious viruses
Solution Approach 1:
The terminal is divided into two distinct operational modes: a first mode for accessing unfamiliar websites and downloading applications, and a second mode for accessing personal information. This segmentation allows the terminal to provide user convenience in the first mode while maintaining security isolation that prevents malicious viruses from compromising personal data in the second mode.
Solution Approach 2:
A mode-switching input unit acts as an intermediary mechanism that allows users to switch between the first and second operational modes. This intermediary provides controlled access between different operational environments, enabling users to transition between convenience-oriented and security-oriented modes as needed.
2Reliability
If the terminal provides multiple operational modes with different access authorities, then security and data protection are improved, but device complexity increases
Solution Approach 1:
The terminal implements dynamic operational modes that can be switched between based on user needs. The system transitions from a static single-mode design to a dynamic multi-mode design where access authorities are adjusted according to the current mode, providing enhanced data protection while managing complexity through flexible configuration rather than rigid architecture.
3Reliability
If the terminal isolates the lock system from the main system, then security and integrity are improved, but ease of operation deteriorates due to potential functionality limitations
Solution Approach 1:
The lock system is designed with multi-functionality to perform various operations including mode switching, data locking, and system configuration. This universality ensures that despite the physical or operational isolation from the main system, the lock system maintains sufficient functionality to provide secure operations while preserving ease of use for users.

AI summary
The disclosure relates to various data processing terminals capable of operating in different modes each of which is granted with different authorities to access hardware or software elements of the terminals. More particularly, a terminal includes a lock system operating in a lock mode and a main system operating in an unlock mode, and erases an entire or a selected portion of results obtained by running operations in the lock mode, when a terminal switches from a lock mode to an unlock mode with greater access authority. Because potentially malicious computer codes which may be impregnated into such results are erased before switching to an unlock mode, the terminal enhances an integrity and a security of a terminal, and improves privacy of a user by preventing loss or unintended disclosure of private data stored in a terminal.
