Sensor Usage Restriction via Sensitivity Area Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User devices, such as smartphones, lack the ability to effectively protect privacy in restricted areas by preventing unwanted recording or sensing, as existing technologies do not adequately restrict sensor usage based on location and sensor capabilities.
Innovation Solution
Implementing a system that includes a blocked location storage server, authentication server, offload server, DRM server, and user device information server to manage and enforce restrictions on sensor usage by determining sensitivity areas and associating them with specific restrictions, allowing only permitted recording or sensing in restricted areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor usage is unrestricted, then user device can record information from any location, but privacy in restricted areas cannot be protected
Solution Approach 1:
The system segments the physical space into restricted and non-restricted areas using geographic coordinates and sensitivity area definitions. Different sensor usage rules are applied to different spatial segments, allowing comprehensive recording in public areas while preventing privacy violations in restricted zones.
Solution Approach 2:
The system applies different quality characteristics to sensor operations based on location. In restricted areas, sensor recording is blocked or limited; in non-restricted areas, full recording capability is maintained. This local differentiation resolves the contradiction between universal recording and privacy protection.
2Object-affected harmful factors
If sensor usage is restricted in all areas, then privacy is protected, but user device cannot record information in permitted areas
Solution Approach 1:
The sensor usage restrictions are dynamic rather than static. The system continuously determines the device's location and adjusts sensor permissions in real-time based on whether the current area is restricted. This allows the sensor to be active in permitted areas while automatically restricting access in protected zones.
Solution Approach 2:
The system introduces an intermediary permission model that mediates between the sensor and the restricted areas. The permission model acts as a gatekeeper, evaluating location data and sensitivity areas to determine whether sensor recording should be permitted, thus preventing information loss in allowed areas while blocking it in restricted zones.
3Object-affected harmful factors
If the system determines sensitivity areas and enforces restrictions, then privacy protection is achieved, but device complexity increases
Solution Approach 1:
The permission model serves multiple functions: it determines sensitivity areas, identifies restricted zones, evaluates sensor requests, and enforces restrictions. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while achieving comprehensive privacy protection.
Solution Approach 2:
The system performs preliminary determination of sensitivity areas and restricted zones before sensor recording occurs. By pre-establishing the permission model and geographic boundaries, the system avoids complex real-time calculations during recording operations, simplifying the overall system architecture.

AI summary
A device is configured to receive a request to use a sensor of a user device. The device determines a sensitivity area associated with the sensor. The sensitivity area indicates an area the sensor is capable of sensing. The device identifies a restricted area in the sensitivity area. The restricted area corresponds to an area from which the user device is limited from use. The user device identifies a restriction associated with the restricted area, generates a response to the request based on the restriction, and provides the response. The response causes the user device to limit use of the sensor, recording of data captured by the sensor, or access to data recorded by the user device even when the user device is located outside of the restricted area.
