Digital ID Verification for Communication Spoofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spoofing attacks in communication systems, where malicious actors send fake messages with forged identities, making it difficult for users to trust the authenticity of received communications, and existing facial recognition methods are computationally intensive, causing delays in message verification.
Innovation Solution
A digital ID verification system that includes a source communication device, a receiver communication device, and a verification system server, where the source device sends a digital ID and communication log to the server, and the receiver device requests authentication, with the server determining and displaying the authenticity of the message source, using hash values and metadata to verify the message's authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial recognition methods are used to verify message authenticity, then the reliability of authentication is improved, but the verification time increases due to computational intensity
Solution Approach 1:
The patent uses digital ID copies and hash values instead of real-time facial recognition. The verification system stores hash values of digital IDs and compares them during authentication, eliminating the need for computationally intensive facial recognition while maintaining authentication reliability.
Solution Approach 2:
The patent replaces the mechanical/computational facial recognition process with a digital hash-based verification system. Instead of processing actual facial images, the system uses cryptographic hash values to verify message authenticity, significantly reducing verification time while maintaining security.
2Productivity
If digital ID verification is performed in real-time, then the productivity of communication is improved, but the device complexity increases due to additional verification components
Solution Approach 1:
The patent introduces a verification system server as an intermediary component that handles the complex verification tasks. The server receives verification requests, compares digital ID hash values, and returns authentication results, allowing client devices to maintain simplicity while achieving real-time verification capability.
Solution Approach 2:
The verification function is segmented between the communication devices and the verification system server. Devices only perform simple hash value comparisons and receive authentication results from the server, dividing the complexity across multiple components rather than placing all verification logic in single devices.
Data Source
AI summary
A system comprises a communication device and an VS server. The communication device is configured to receive, a communication message comprising a digital identifier (ID) from a source communication device; send a verification request for receiving an authentication result of the digital ID, wherein the verification request includes the digital ID; and display a visual identifier in response to receiving the authentication result. The VS server is coupled to the communication device and configured to receive, from a source communication device, first registration information of a sender, wherein the sender is associated with the source communication device; receive, from the communication device, the verification request that instructs the VS server to authenticate the communication message, wherein the communication message includes the digital ID; determine an authentication result based on the first registration information and the digital ID; and send, to the communication device, the authentication result.
