Silent Caller ID Verification With Registered Device Callback Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional caller identity verification methods are cumbersome, insecure, and inefficient, making it easy for attackers to spoof caller identities, especially with the convergence of IP and telephony.
Innovation Solution
A silent caller identity verification mechanism that utilizes the states and state transitions of a registered device to authenticate phone calls by comparing them with observed call states, using an authentication server to verify that the call originates from a legitimate device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional caller ID verification methods are used, then caller identity can be verified, but the verification process becomes cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary actions by pre-registering device identifiers and establishing baseline call state patterns before verification is needed. When a call comes in, the system compares real-time call states against pre-established patterns, enabling rapid verification without time-consuming interactive challenges
Solution Approach 2:
The verification system operates autonomously by automatically comparing call states with registered device patterns without requiring user intervention. The system self-verify the caller's identity through background processing of call state data, eliminating the need for users to answer security questions or perform manual verification steps
2Reliability
If conventional verification methods requiring user interaction are used, then security can be maintained, but user experience deteriorates
Solution Approach 1:
The verification mechanism operates completely autonomously in the background, comparing call states with registered device patterns without any user awareness or interaction needed. Users simply make or receive calls normally while the system silently verifies authenticity through automated state comparison
Solution Approach 2:
The verification process is extracted from the user interaction flow and placed entirely in the system's background operations. By separating the verification function from user actions, the system maintains high security through automated checks while preserving smooth user experience without friction
3Adaptability or versatility
If IP and telephony convergence is implemented, then communication flexibility improves, but caller ID spoofing becomes easier
Solution Approach 1:
The system continuously monitors call states and provides feedback by comparing them against registered device patterns. This real-time feedback mechanism detects anomalies that indicate spoofing attempts, maintaining security even as IP and telephony convergence enables greater communication flexibility
Solution Approach 2:
The verification system acts as an intermediary layer between the converged IP/telephony network and the caller ID verification process. It mediates by intercepting call state data, comparing it with registered patterns, and validating authenticity before allowing communication, thus preventing spoofing while preserving network flexibility

AI summary
Disclosed herein are embodiments of systems, methods, and products comprises an authentication server for caller ID verification. When a caller makes a phone call, the server receives the phone call and verifies whether the phone call is from a registered device associated with the phone number. The server queries the registered device to retrieve one or more current call states via an authentication function on the registered device. The server compares the states and/or state transitions to the observed states and/or state transitions of the phone call. If the registered device states and/or state transitions match the observed phone call states and/or state transitions, the server verifies that the phone call is from the registered device and not some imposter's device. If there is no such match, the server rejects the phone call before the call phone is connected or terminates the phone call after the phone call is connected.
