Sensor Access Authority Management for Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authorization mechanisms for sensors in mobile devices are inadequate in protecting user privacy due to advancements in sensor technology, which enable sensors to detect and collect types of information beyond their original intent, leading to potential privacy leakage.
Innovation Solution
A method and device that determine a second sensor corresponding to a first sensor with a different type, and adjust the access authority of an application program to the second sensor based on the adjustment of the first sensor's access authority, thereby preventing privacy information leakage by limiting access to data collected by the second sensor when its sampling rate and precision exceed certain thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor sampling precision and sampling rate are improved, then sensor detection capability is enhanced, but user privacy security deteriorates
Solution Approach 1:
The system performs preliminary actions by determining corresponding sensors and adjusting their access authorities before privacy leakage can occur. When a user adjusts access authority for one sensor, the system proactively identifies other sensors that could collect similar information and adjusts their authorities in advance, preventing potential privacy breaches before they happen.
Solution Approach 2:
The system implements feedback by continuously monitoring sensor access authority adjustments and automatically responding by identifying corresponding sensors and adjusting their authorities. This closed-loop feedback mechanism ensures that privacy protection measures are dynamically updated based on user actions and sensor capabilities, maintaining security as sensor precision improves.
2Ease of operation
If existing authorization mechanism is used, then application access control is simplified, but privacy protection effectiveness deteriorates
Solution Approach 1:
The system applies universality by creating a comprehensive authorization mechanism that works across multiple sensor types simultaneously. Instead of treating each sensor independently, the system identifies corresponding sensors and applies access authority adjustments universally to all sensors that could collect similar information, enhancing privacy protection while maintaining operational simplicity through automated multi-sensor management.

AI summary
The application provides a managing method and device for a sensor access authority, and relates to the field of information security. The method includes: determining a second sensor corresponding to a first sensor and having a type different from the first sensor in response to adjustment of an access authority of an application program to the first sensor, and then adjusting the access authority of the application program to the second sensor. The second sensor corresponding to a first sensor is determined when an access authority of an application program to the first sensor is adjusted, and the access authority of the application program to the second sensor is adjusted, thereby avoiding the second sensor collecting and leaking privacy information of the user and protecting privacy security of the user.
