Sensing Authorization for Privacy-Protected Object Perception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to adequately protect the privacy of sensing targets and non-sensing targets within a sensing range, particularly in scenarios involving wireless electromagnetic wave signals, as they lack effective authorization mechanisms for objects that are not traditional UEs.
Innovation Solution
A sensing authorization method and device that transmit and receive authorization information, including characteristic, subscription, and identification information of objects, to manage and protect privacy by determining permissible sensing actions and screening or deleting sensitive data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless electromagnetic wave signals are used for environmental sensing, then sensing capability is achieved, but privacy of sensing targets and non-sensing targets cannot be protected
Solution Approach 1:
The patent implements preliminary authorization actions before sensing operations. The network element stores authorization information for multiple objects in advance, including identification information and authorization status. When sensing is performed, the system queries this pre-stored authorization information to determine whether sensing is permitted, thereby preventing privacy leakage before it can occur.
Solution Approach 2:
The patent introduces a network element as an intermediary between the sensing function and objects. This network element manages authorization information, receives sensing requests, queries authorization status, and controls whether sensing can proceed. This intermediary layer ensures that privacy protection is enforced without compromising the sensing capability of the wireless electromagnetic wave signals.
2Object-affected harmful factors
If sensing authorization mechanisms are implemented for non-UE objects, then privacy protection is improved, but system complexity increases
Solution Approach 1:
The patent designs a universal authorization management mechanism that handles multiple object types (UE devices, non-UE objects, sensing targets, and non-sensing targets) through a single system. The network element stores and manages authorization information for all object types uniformly, using consistent identification information and authorization status fields, thereby avoiding the need for separate complex systems for different object types.
Solution Approach 2:
The patent uses identification information as a copy or representation of the actual object. Instead of directly managing complex object attributes and privacy settings, the system stores simplified identification information (such as device identifiers or object identifiers) and corresponding authorization status. This copying approach reduces system complexity while maintaining effective privacy protection.
