Pre-Call Biometric Authentication for 5G Voice and Video Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice and video calls lack robust pre-call identity authentication, making them susceptible to unlawful acts such as telephone harassment and privacy theft, as caller identity verification is only possible after connection.
Innovation Solution
Implementing a 5G message-based call identity authentication method that acquires biometric authentication information, such as facial images or voice samples, before call setup, and displays authentication results to enhance user security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication information is transmitted through 5G messages before call setup, then caller identity verification is improved, but communication protocol complexity increases
Solution Approach 1:
The patent implements biometric authentication information transmission through 5G messages before call setup is completed. The calling terminal device sends biometric data (face images, voiceprints, or fingerprints) in the 5G message during the call establishment phase, allowing the called terminal to verify the caller's identity in advance. This preliminary authentication action resolves the contradiction by establishing reliability before the call connects, rather than requiring complex post-connection verification protocols.
Solution Approach 2:
The patent introduces biometric authentication information as an intermediary element between the calling and called terminal devices. Instead of directly verifying identity through complex protocol handshakes, the system uses biometric data (face images, voiceprints, or fingerprints) transmitted through 5G messages as a mediator. The called terminal compares this biometric data with stored reference data to authenticate the caller, simplifying the overall verification process while maintaining high reliability.
2Reliability
If pre-call authentication is implemented, then communication security is improved, but call setup time increases
Solution Approach 1:
The patent merges the authentication process with the existing call setup procedure by transmitting biometric authentication information through 5G messages during the call establishment phase. Instead of adding a separate authentication step that would extend call setup time, the system combines identity verification with the routine message exchange already occurring during call setup. This integration allows security verification to occur simultaneously with normal protocol operations, minimizing additional time loss.
Solution Approach 2:
The patent performs biometric authentication in advance during call setup rather than after connection. By sending and verifying biometric information (face images, voiceprints, or fingerprints) in the 5G message before the call is fully established, the system secures communication beforehand. This preliminary action prevents potential security issues before they arise and allows the call to proceed directly once authentication succeeds, avoiding post-connection verification delays.
3Measurement precision
If biometric data is transmitted through 5G messages, then authentication capability is improved, but data transmission requirements increase
Solution Approach 1:
The patent extracts only the essential biometric authentication information needed for verification and transmits it through 5G messages. Instead of transmitting complete biometric datasets or multiple types of biometric data, the system selectively extracts and sends only the necessary authentication elements (such as face images, voiceprints, or fingerprints). This extraction approach maintains high authentication capability while minimizing the quantity of data transmitted, as only the critical verification information is included in the 5G message.
Solution Approach 2:
The patent applies different authentication approaches based on local conditions and requirements. The system can select from multiple biometric data types (face images, voiceprints, fingerprints) depending on the specific communication scenario, device capabilities, and security requirements. This localized adaptation allows the system to transmit only the appropriate type and amount of biometric data for each situation, optimizing authentication capability while controlling data transmission requirements according to local needs.

AI summary
A call identity authentication method, a terminal device and a computer-readable storage medium are disclosed. The method may include: in response to receiving a call setup request from a calling terminal device, acquiring biometric authentication information sent from the calling terminal device through a fifth generation (5G) message (S100); obtaining an authentication result according to the biometric authentication information (S200); and displaying authentication notification information according to the authentication result (S300).
