Call Verification System for Voice Phishing Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice phishing poses a significant challenge as it is difficult for authorities to monitor and trace, and consumers are vulnerable to fraudulent calls that appear to be from trusted sources, necessitating a method to verify the identity of callers and recipients to prevent information theft.
Innovation Solution
A call verification system that authenticates both the service provider and client, sending notifications to confirm the legitimacy of incoming calls and ensuring that both parties are verified before establishing a connection, using API keys, secrets, and verification credentials to ensure secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If call verification is implemented to prevent voice phishing, then security and reliability are improved, but device complexity and system complexity increase
Solution Approach 1:
The patent introduces a verification system as an intermediary component between the communication network and user devices. This verification system receives call requests, verifies caller identities through multiple factors (device ID, caller ID, biometric data), and provides verification indicators to recipient devices. By centralizing verification functions in a dedicated intermediary system, the complexity is contained and managed separately while providing enhanced reliability to the overall communication system.
Solution Approach 2:
The verification system is segmented into distinct functional modules: a verification module that receives and processes call requests, a verification indicator generation module that creates security indicators, and a notification module that communicates verification status to recipient devices. This segmentation allows each module to be optimized independently and simplifies the overall system architecture while maintaining high reliability through specialized verification functions.
2Reliability
If identity verification of both service provider and client is performed, then security against voice phishing is improved, but loss of time in call establishment increases
Solution Approach 1:
The system performs preliminary verification actions by generating and transmitting verification indicators before the actual call connection is established. The verification system processes caller identity information in advance, creates verification indicators (such as visual or auditory security tokens), and sends these indicators to the recipient's device. This preliminary action allows the recipient to verify the caller's identity before answering, reducing the perceived time delay while maintaining security.
Solution Approach 2:
The verification system implements feedback mechanisms by providing real-time verification status information to both the service provider and the client. The system monitors the verification process, communicates verification results through notifications and indicators, and allows for rapid decision-making. This feedback loop enables efficient call establishment by providing immediate verification information without requiring lengthy manual verification procedures.

AI summary
Systems and methods for providing call verification to prevent voice phishing, comprising: receiving a first API call, wherein the first API call is a call request from a service provider to establish a call with a client device associated with a client of the service provider; verifying an identity of the service provider, wherein verifying the identity of the service provider comprises: generating a second API call; transmitting the second API to a verification system; and receiving verification of the service provider from the verification system; transmitting a notification to the client device that includes an indication that an incoming call is from a verified service provider; verifying the identity of the client; and establishing the call between the service provider and the client after both the identity of the service provider and the identity of the client are verified.
