Dynamic Security Labeling for Electronic Device Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and poor experience when they forget their security password, as they cannot unlock or boot their electronic devices, thereby preventing access to basic functions.
Innovation Solution
The control method determines the operating mode of a target application based on user input, where collection data is secured with a security label in one mode and accessible without it in another, ensuring data protection and allowing access even if the user forgets the password.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security password is set for unlocking or booting the terminal, then data security is improved, but user convenience deteriorates when the user forgets the password
Solution Approach 1:
The patent segments data into two categories: security-labeled data and non-security-labeled data. Security-labeled data requires password verification for access, while non-security-labeled data is accessible without password. This segmentation allows the system to maintain strong security for sensitive data while providing convenient access to non-sensitive data, thereby resolving the contradiction between data security and user convenience.
2Reliability
If security label is applied to collection data, then data protection is improved, but access flexibility deteriorates
Solution Approach 1:
The patent implements dynamic security labeling where the security label is not fixed but can be adjusted based on user input operations. When a security operation (such as fingerprint scanning) is detected, the system applies security labeling to protect data. When no security operation is detected, the system removes security labeling to allow flexible access. This dynamic approach enables the system to adapt security levels according to real-time user behavior, resolving the contradiction between data protection and access flexibility.

AI summary
An electronic device and a control method thereof are provided. The control method for the electronic device includes: acquiring a call instruction; calling a target application to acquire collection data; acquiring a security label, in a case that the target application operates in a first operating mode; storing the acquired collection data based on the security label, as a collection data with the security label, wherein the collection data with the security label is in an accessible state when a first access authority is met.
