Cross-OS Data Encryption and Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminals fail to securely transfer data from a common system to a security system, as data is displayed in both copying and copied positions, compromising security and risking data loss.
Innovation Solution
The method involves acquiring a target entering key for the security system, encrypting data using this key, and concealing it in the common system, ensuring only authorized access and preventing unauthorized viewing or data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is copied from the common system to the security system, then data security is improved, but data accessibility deteriorates because the data cannot be exported from the security system
Solution Approach 1:
The patent segments data storage into two distinct systems: common system for general storage and security system for sensitive data. The security system further segments data into visible and hidden portions, allowing selective access while maintaining overall security. This segmentation resolves the contradiction by enabling security-critical data to be isolated while keeping non-critical data accessible.
Solution Approach 2:
The patent introduces an intermediary mechanism (the hidden portion in the security system) that acts as a mediator between the security requirements and accessibility needs. This intermediary allows authorized access to specific data portions while maintaining the security constraint that prevents unauthorized export, thus resolving the contradiction between security and accessibility.
2Ease of operation
If data is displayed in both copying and copied positions, then data accessibility is improved, but data security deteriorates as others can easily see contact information
Solution Approach 1:
The patent divides the security system into two distinct portions: a visible portion for general access and a hidden portion for sensitive data. This segmentation ensures that contact information and other sensitive data stored in the hidden portion cannot be easily viewed by others, while still allowing the user to access their own data. This directly resolves the contradiction by preventing unauthorized viewing while maintaining user accessibility.
Solution Approach 2:
The patent applies different security qualities to different portions of the security system. The visible portion has higher accessibility with lower security restrictions, while the hidden portion has lower accessibility with higher security protections. This local differentiation of security qualities resolves the contradiction by allowing data to be accessible where appropriate while maintaining security where critical.
3Reliability
If data is moved to the security system, then data security is improved, but data loss risk increases because exported data cannot be obtained
Solution Approach 1:
The patent implements a copying mechanism where data can be copied from the common system to the security system while maintaining the ability to retrieve it. The hidden portion of the security system acts as a secure copy that can be accessed by the user but cannot be exported to external devices. This resolves the contradiction by providing secure storage that prevents unauthorized loss while allowing legitimate user access.
Solution Approach 2:
The patent inverts the traditional export-import model by implementing a hidden portion that prevents export while allowing import and user access. Instead of allowing free export and restricting import, the system restricts export while enabling user retrieval through the hidden portion. This inverted approach resolves the contradiction between security and data loss prevention.

AI summary
The invention provides an information processing method and an information processing device. The information processing method and the information processing device are applied to a terminal that comprises a plurality of operating systems. The information processing method comprises: upon receiving an instruction of copying data information in an arbitrary operating system to a specified operating system among the plurality of operating systems, acquiring a target entering key of the specified operating system; and after copying the data information to the specified operating system, encrypting the data information in the arbitrary operating system by using the target entering key of the specified operating system, or not displaying the data information in the arbitrary operating system again. The technical solution guarantees that data are not lost and also guarantees that data are not easy to divulge.
