Continuous 5G Service Assessment via Biometric Trust Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G network access management lacks continuous validation of user and device authenticity, leading to potential unauthorized use and tampering, as existing methods only perform one-time authentication and authorization without dynamic reauthorization mechanisms.
Innovation Solution
Implementing a trust-based continuous service assessment system that utilizes biometric and behavioral data analysis within a Trusted Execution Environment (TEE) to periodically verify user identity and device integrity, with a trust score mechanism for reauthorization, ensuring authorized access and protecting user data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-time authentication and authorization is used for 5G network access, then the access management process is simple and fast, but the security is insufficient due to lack of continuous validation
Solution Approach 1:
The system performs preliminary authentication and authorization during initial network access, establishing a baseline trust relationship. This preliminary action enables subsequent continuous validation without requiring full re-authentication, balancing security with operational simplicity.
Solution Approach 2:
The patent implements continuous service assessment that operates throughout the entire network access session. Instead of stopping at one-time authentication, the system continuously monitors service usage patterns, device status, and subscription validity, maintaining ongoing security validation without interrupting legitimate service.
2Measurement precision
If continuous service assessment with biometric and behavioral data analysis is implemented, then user identity validation is enhanced, but processing overhead and system complexity increase
Solution Approach 1:
The patent introduces a service assessment function as an intermediary component that handles the complex analysis of biometric and behavioral data. This mediator processes authentication information, device status, and service usage patterns, then provides validation results to the network management system, isolating complexity from core network functions.
Solution Approach 2:
The system utilizes device-generated data such as usage patterns, service consumption behavior, and device status information that automatically reflect current operational state. This self-service approach allows the system to validate user identity and device integrity using data that continuously updates without requiring active user participation or complex external verification systems.
3Reliability
If dynamic reauthorization mechanisms are added to 5G network access, then unauthorized use is prevented, but the access management process becomes more complex and slower
Solution Approach 1:
The system performs service assessment at periodic intervals during the network access session, checking subscription validity, device status, and service usage patterns at defined checkpoints. This periodic validation ensures authorization remains valid without requiring constant verification, maintaining security while preserving access management efficiency.
Solution Approach 2:
The continuous service assessment function provides feedback to the network management system about current service usage, device status, and authentication validity. This feedback mechanism enables dynamic reauthorization decisions based on real-time conditions, allowing the system to maintain or adjust access permissions without manual intervention or complete re-authentication processes.

AI summary
A trust based continuous Fifth Generation (5G) network service assessment, and more specifically a trust based continuous 5G network service assessment for a user equipment to ensure an authorized user is using the user equipment may be provided. A registration request may be received by an Access and Mobility Management Function (AMF) from a User Equipment (UE). In response to the registration request, a Policy Control Function (PCF) may exchange a policy with the AMF, wherein the policy comprises instructions to perform a continuous service assessment. Next, a registration accept message may be sent to the UE, wherein the registration accept message comprises instructions for the UE to enable the continuous service assessment.
