Sidelink UE Privacy Verification for Authorized Positioning Data Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing sidelink (SL) positioning and ranging technologies lack effective privacy verification mechanisms to ensure that only authorized user equipment (UE) can access privacy data during SL positioning services, leading to potential exposure of sensitive user information.

Innovation Solution

Implement a privacy verification method and terminal devices that utilize identification and privacy verification information to determine whether an SL positioning client UE is authorized to acquire privacy data, involving a processor, transceiver, and memory to manage privacy verification results and execute instructions for authorization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If SL positioning services are provided without privacy verification mechanisms, then positioning functionality is achieved, but user privacy data is exposed to unauthorized access

Engineering Contradiction:

Improveprivacy protectionVSAvoidverification system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements privacy verification before providing SL positioning services. The first UE performs verification by comparing the identification information of the SL positioning client UE with stored privacy verification information to determine authorization status in advance, preventing unauthorized access before it occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the positioning service provision into distinct phases: authorization verification phase and service execution phase. The verification process is separated from the positioning service itself, allowing independent validation of authorization status before data sharing occurs.

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If privacy verification mechanisms are implemented, then unauthorized access to privacy data is prevented, but additional verification steps increase system complexity

Engineering Contradiction:

Improveunauthorized data accessVSAvoidverification process complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent extracts the privacy verification function as a separate, independent process from the main positioning service. The first UE independently performs verification by extracting and comparing identification information against stored verification data, isolating the security check from the positioning logic.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The first UE performs self-verification by using its own stored privacy verification information to validate the SL positioning client UE's authorization. The system serves its own security needs without requiring external verification authorities, reducing overall system complexity.

Inventive Principle:

Principle #25Self-service

AI summary

Provided is a method for privacy verification. The method is performed by a first user equipment (UE), and includes: acquiring a privacy verification result of the first UE based on identification information of a sidelink (SL) positioning client UE and privacy verification information of the first UE, wherein the privacy verification result is used to indicate whether the SL positioning client UE is authorized to acquire privacy data of the first UE.
