Network-Mediated Sensing Authorization for Non-UE Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to adequately protect the privacy of non-UE objects within a sensing range by not addressing authorization for sensing targets other than the UE, leading to potential privacy leaks of surrounding objects.
Innovation Solution
A sensing authorization method involving transmission and reception of authorization information, including characteristic, subscription, and identification data of objects, to determine and manage sensing permissions, with network elements performing data screening and task termination as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing capability is supported in communication network to achieve environmental sensing, then sensing function is improved, but privacy protection of non-sensing targets deteriorates
Solution Approach 1:
The patent implements preliminary authorization management by requiring devices to obtain authorization information before sensing operations. The network element stores authorization information for multiple objects, and the sensing device queries this information in advance to determine which objects can be sensed and which are prohibited, preventing privacy leaks before they occur.
Solution Approach 2:
The patent introduces a network element as an intermediary between the sensing device and the objects to be sensed. This network element manages authorization information, receives queries from sensing devices, and provides authorization decisions, thereby mediating the sensing process to protect privacy while enabling legitimate sensing functions.
2Object-affected harmful factors
If authorization information is transmitted and managed for multiple objects, then privacy protection is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal authorization management system where the network element serves multiple functions: storing authorization information for multiple objects, receiving queries from different sensing devices, providing authorization decisions, and managing prohibition indications. This multi-functional approach consolidates complexity into a single network element rather than requiring separate systems for each sensing operation.
Solution Approach 2:
The patent uses identification information as a copy or representation of the actual objects. Instead of managing complex data about each physical object, the system manages authorization information tied to identification data, which can be queried and processed efficiently while maintaining the necessary privacy protection capabilities.

AI summary
A sensing authorization method comprises includes: transmitting, by a first device, first authorization information of a first object to a first network element, where the first authorization information of the first object includes at least one of: characteristic information of the first object; first request information; subscription information of the first object; or identification information of the first object and/or a first indication of the first object.
