Cellular Sensing Authorization for Privacy of Affected Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication and sensing integration in cellular networks fail to adequately protect the privacy of electronic devices affected by sensing tasks, as they only authorize the target object without considering the privacy of other devices within the sensing area.
Innovation Solution
A communication method and device that identify and authorize electronic devices within a target sensing area by sending messages to network devices, ensuring that all affected devices are protected, including network devices and terminal devices, through a communication system that supports device-to-device communication, machine-to-machine communication, and vehicle-to-everything communication, using network elements like AMF, SF, and NEF to manage sensing tasks and privacy checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless electromagnetic wave signals are used for sensing tasks, then sensing capability is improved, but privacy leakage of affected electronic devices occurs
Solution Approach 1:
The patent implements authorization checks before executing sensing tasks. The network device obtains authorization information from affected electronic devices prior to performing sensing operations, ensuring that privacy protection measures are established in advance rather than as a reactive measure after privacy leakage occurs.
Solution Approach 2:
The patent introduces an authorization management mechanism as an intermediary between sensing tasks and affected devices. The network device acts as a mediator that coordinates between the sensing task initiator and affected electronic devices, managing authorization information and ensuring proper consent is obtained before sensing operations proceed.
2Ease of operation
If only target object authorization is implemented, then authorization process is simplified, but privacy of other affected devices is not protected
Solution Approach 1:
The patent segments the authorization process into distinct components: identifying the target object, identifying affected electronic devices within the sensing area, and obtaining separate authorization information from each. This segmentation ensures that while the target object is clearly defined, additional affected devices are not overlooked and receive appropriate protection.
Solution Approach 2:
The patent implements a feedback mechanism where the network device determines whether authorization information has been obtained for all affected electronic devices. If authorization is missing for any device, the system provides feedback to request the necessary authorization before proceeding, ensuring complete privacy protection.
3Reliability
If sensing area coverage is expanded, then sensing effectiveness is improved, but number of affected devices increases
Solution Approach 1:
The patent performs preliminary identification of all electronic devices within the sensing area before executing the sensing task. By determining the complete set of affected devices in advance, the system can prepare appropriate authorization checks and privacy protection measures, ensuring that expanded sensing coverage does not result in overlooked privacy violations.
Solution Approach 2:
The network device serves as an intermediary that manages the relationship between expanded sensing coverage and affected devices. It coordinates the identification of all devices within the sensing area, obtains necessary authorization information, and ensures that privacy protection scales appropriately with the number of affected devices.
