Application Permission Assignment via Image Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal security methods fail to differentiate user permissions effectively, leading to privacy leaks and poor user experience, as all users with successful unlock access have the same permissions, regardless of their relationship to the primary user.
Innovation Solution
A method and device that collect and match user images to assign application usage permissions, where a pre-stored target image grants all permissions, a stranger image grants partial permissions based on a collection count threshold, and no match results in no permissions, ensuring differentiated access and enhanced privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital password security locking is used for mobile terminal or application, then security protection is provided, but all users who successfully unlock obtain the same usage permissions regardless of their relationship to the primary user, leading to privacy leakage
Solution Approach 1:
The patent applies local quality by assigning different usage permissions to different users based on their relationship to the primary user. Instead of giving uniform permissions to all users who successfully unlock, the system differentiates permissions locally for each user (e.g., family members get different permissions than friends or strangers), thereby preventing privacy leakage while maintaining security protection.
Solution Approach 2:
The patent segments the user permission system into multiple permission levels based on user relationships. By dividing permissions into different categories (such as full access for family members, limited access for friends, and no access for strangers), the system resolves the contradiction between providing security protection and preventing privacy leakage caused by uniform permission assignment.
2Ease of operation
If uniform usage permissions are assigned to all users who successfully unlock, then ease of operation is improved, but privacy of the primary user is leaked and user experience deteriorates
Solution Approach 1:
The system implements local quality by customizing permissions for different user groups rather than applying uniform permissions to all users. This allows the system to maintain ease of operation through automated permission assignment while preventing privacy loss by restricting access appropriately for each user type.
3Loss of information
If image matching technology is used to differentiate user permissions, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The patent uses image matching technology where the system captures and stores reference images of authorized users. When a user attempts to access the device, the system compares the current user's image against stored reference images to determine permission levels. This copying approach (storing image copies for comparison) enables automated privacy protection without requiring complex manual permission configuration, thereby managing device complexity.
Solution Approach 2:
The system implements self-service by automatically differentiating user permissions through image matching without requiring manual intervention for each access attempt. The device autonomously determines user identity and assigns appropriate permissions based on pre-configured user profiles, reducing the operational complexity despite the advanced technology used.

AI summary
The present disclosure related to a method and device for assigning application usage permission. The method includes: collecting a first image of a current first user, and when it is recognized that a target application is enabled, judging whether the first image matches a target image corresponding to the target application (S101); if yes, assigning all usage permissions of the target application to the current first user (S102); if not, judging whether there is a first stranger image matching the first image successfully (S103); if yes, assigning a corresponding usage permission of the target application to the current first user according to a collection count corresponding to the first stranger image and a usage permission corresponding to a collection count range threshold (S104); and if not, not assigning the usage permission of the target application to the current first user (S105).
