Visual Voicemail Authentication for 5G Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G networks face increased security threats due to higher data volumes and types, with existing multi-factor authentication methods lacking robustness and flexibility to effectively protect personal and private information.
Innovation Solution
Implementing visual voicemail as an additional authentication factor, using contextual information and network entity profile data to generate customizable visual voicemail messages in multiple formats, which can be validated in various formats such as audio, text, or video, enhancing security and flexibility for 5G network authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-factor authentication is used (texting passcode to wireless device), then authentication is provided, but robustness and flexibility are insufficient for 5G network security requirements
Solution Approach 1:
The patent implements dynamic authentication by allowing the authentication mechanism to adapt its behavior based on contextual information. The system adjusts authentication requirements and methods in real-time based on factors such as user behavior patterns, device characteristics, and environmental context, making the authentication system both more secure and more flexible simultaneously
Solution Approach 2:
The patent changes multiple authentication parameters including the type of factors required (knowledge, possession, inherence), the complexity of verification processes, and the thresholds for trust decisions. By dynamically adjusting these parameters based on contextual information, the system achieves both enhanced security and improved adaptability
2Reliability
If more authentication factors are added to mitigate breach risk, then security is improved, but the system lacks robustness and flexibility desirable for 5G networks
Solution Approach 1:
The patent implements a universal authentication framework that can handle multiple types of authentication factors (knowledge-based, possession-based, inherence-based) through a single unified mechanism. This multi-functional approach allows the system to provide comprehensive security without proportionally increasing complexity, as the same core architecture supports diverse authentication methods
Solution Approach 2:
The patent introduces an intermediary authentication manager that coordinates between multiple authentication factors and the core authentication system. This mediator layer simplifies the overall system architecture by providing a standardized interface for handling diverse authentication requirements, reducing the apparent complexity while maintaining strong security
3Adaptability or versatility
If visual voicemail is used as authentication factor, then robustness and flexibility are enhanced, but additional authentication infrastructure is required
Solution Approach 1:
The patent merges the authentication functionality with the existing visual voicemail service infrastructure. By combining authentication delivery with a familiar user service (voicemail), the system enhances flexibility without requiring entirely new infrastructure, as the authentication messages are delivered through the existing voicemail channels
Data Source
AI summary
A method performed by a wireless device on a wireless network. The method includes sending an access request for an application. In response to sending the access request, the wireless device receives a visual voicemail message including authentication information. The wireless device can access and send the authentication information of the visual voicemail message to an authentication system. The wireless device is then authenticated to participate in a restricted activity or access restricted content in response to the sent authentication information.
