Solution Overview

Problem

Current caller ID services are vulnerable to spoofing, where the displayed caller ID information is falsified, compromising the integrity of the service and potentially leading to unlawful or mischievous activities.

Innovation Solution

Implementing a validation system within communication networks to verify the authenticity of caller ID information by comparing originating node data with caller ID data, ensuring that the call originated from the stated node, thereby distinguishing valid from counterfeit information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If caller ID information is provided without validation, then the service is simple and easy to operate, but the reliability and integrity of the information is compromised due to spoofing

Engineering Contradiction:
Improveintegrity of caller ID informationVSAvoidcomplexity of validation system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a validation system as an intermediary component between the caller ID service and the called party's equipment. This validation system receives caller ID information, verifies its authenticity by checking against network records, and only permits display of validated information. The intermediary adds reliability without requiring changes to the core caller ID service infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The validation system performs preliminary verification of caller ID information before it is displayed to the called party. By checking the authenticity of the caller ID data in advance (before the call connects or during the ringing phase), the system prevents spoofed information from reaching the display, thereby ensuring reliability without complicating the user experience.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If caller ID spoofing is allowed, then the service provider can offer basic caller ID functionality with minimal complexity, but the service becomes vulnerable to harmful factors and loses value

Engineering Contradiction:
Improvevulnerability to spoofing attacksVSAvoidtrustworthiness of caller ID service
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The validation system implements preliminary anti-action by proactively detecting and blocking spoofed caller ID information before it can harm the called party. The system compares the provided caller ID against network records and originator information, and rejects fraudulent data in advance, thereby preventing the harmful effect of spoofing while maintaining service reliability.

Inventive Principle:
Principle #9Preliminary anti-action

3Reliability

If validation systems are implemented to verify caller ID authenticity, then the reliability of the service improves, but the device complexity and processing requirements increase

Engineering Contradiction:
Improveaccuracy of displayed caller IDVSAvoidcomplexity of call signaling processing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The validation function is extracted as a separate, dedicated system or module within the network infrastructure. Rather than embedding validation logic throughout the entire call processing system, the patent isolates the validation functionality into a specific component that handles verification tasks. This extraction manages complexity by creating a specialized subsystem with a single focused function.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Caller ID validation system and methods are provided. When a call is placed over a communication network, a validation system receives the call signaling, and processes the call signaling to identify originating node information in the call signaling. The originating node information is inserted by the communication network when handling the call and pertains to a network node that originates the call into the network. The validation system also processes the call signaling to identify caller ID information for the call. The validation system then processes the originating node information and the caller ID information to determine whether the call originated from the originating node. If the call did originate from the originating node, then the validation system determines that the caller ID information is valid.
