Secure Object Transfer Between Independent Storage Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock screen passwords on electronic devices provide inadequate security, leading to potential leaks of sensitive information when the password is compromised.
Innovation Solution
A method and apparatus for moving objects, such as files or applications, from a main space to a secondary, secure space within an electronic device, ensuring the secondary space is enabled and has sufficient capacity, and employing encryption and decryption processes to enhance privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock screen password is used to protect information, then basic security is provided, but the security level remains low and privacy information may be leaked when the password is compromised
Solution Approach 1:
The storage space is segmented into a first space and a second space, where the second space is specifically designed for storing privacy information with higher security requirements. This segmentation allows different security levels to be applied to different types of data, resolving the contradiction by providing enhanced security for sensitive information without requiring the entire system to become overly complex.
Solution Approach 2:
A switch control is introduced as an intermediary mechanism between the user and the privacy information storage. This switch control, when activated, triggers the movement of privacy information from the first space to the second space and enables the second space for encrypted storage. The intermediary provides a simple user interface that masks the underlying complexity of the dual-space security system.
2Reliability
If privacy information is stored in the first space, then storage is simple and accessible, but the information is vulnerable to unauthorized access when the lock screen password is leaked
Solution Approach 1:
The storage system is divided into two distinct spaces: the first space for general information and the second space for privacy information. The second space implements independent encrypted storage, ensuring that even if the lock screen password is compromised, the privacy information remains protected. This segmentation resolves the contradiction by providing both security and accessibility through spatial separation.
Solution Approach 2:
The system changes the storage parameter of privacy information by moving it from the first space to the second space when the switch control is activated. This parameter change involves altering the storage location and encryption status, transforming the information from easily accessible but vulnerable storage to securely encrypted storage that requires additional authentication, thus resolving the contradiction between privacy protection and access convenience.
3Reliability
If the second space is enabled for encrypted storage, then security is enhanced, but the device complexity and operational steps increase
Solution Approach 1:
The switch control serves as an intermediary that simplifies the complex process of enabling the second space for encrypted storage. When the user activates the switch control, the system automatically handles the movement of privacy information to the second space and enables the encrypted storage functionality. This intermediary mechanism resolves the contradiction by providing a simple user interface that masks the underlying complexity of space management and encryption setup.

AI summary
An object movement method includes receiving a first input of a user, where the first input is used to move a target object in a first space into a second space; and in response to the first input, moving the target object into the second space in a case that the second space is enabled and that a size of a residual space of the second space meets a predetermined condition, where the second space and the first space are independent of each other.
