Telephone Call Processor Signal Detection and Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephone call processing systems lack secure methods for transmitting sensitive personal and financial information over telephone networks, as existing methods rely on trust in call center staff and are vulnerable to data recording and theft, leading to risks of fraud and identity theft.
Innovation Solution
A telephone call processor that can switch between modes to block data signals while allowing voice communication, using DTMF tones and CTI signals to manage data transmission securely, ensuring sensitive information is not disclosed to call center agents, and utilizing a processor to mask or convert data signals to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensitive information is transmitted over telephone networks using existing methods, then communication between caller and call center is enabled, but security is compromised due to vulnerability to data recording and theft by call center staff
Solution Approach 1:
The patent introduces an intermediary device between the caller and call center that intercepts and processes data signals. This intermediary blocks sensitive information from reaching the call center while allowing legitimate communication to proceed, thereby resolving the security vulnerability without compromising communication functionality
Solution Approach 2:
The patent extracts and removes sensitive data signals from the communication stream before they can be transmitted to the call center. By taking out the harmful element (sensitive information) from the system, the patent prevents data exposure while maintaining the overall communication function
2Reliability
If data signals are blocked to prevent theft, then security is improved, but legitimate data transmission functionality is lost
Solution Approach 1:
The patent applies different treatment to different parts of the communication stream. Legitimate data signals are allowed to pass through to the call center, while sensitive data signals are blocked. This local differentiation resolves the contradiction by maintaining data transmission functionality for non-sensitive information while securing sensitive information
3Ease of operation
If trust-based methods are used for information transmission, then ease of operation is maintained, but security reliability deteriorates due to dependence on staff integrity
Solution Approach 1:
The patent implements a self-service security mechanism where the communication system automatically identifies and blocks sensitive information without requiring manual intervention or trust in staff. The system protects itself by inherently preventing data theft, thereby maintaining operational simplicity while improving security reliability

AI summary
A telephone call processor for processing telephone calls comprising voice signals and data signals, the call processor comprising a first telephone interface and a second telephone interface, the call processor being operable in a first mode and in a second mode. In the first mode, the call processor is adapted to receive voice signals and data signals at the first telephone interface and to transmit voice signals and data signals via the second telephone interface. In the second mode, the call processor is adapted to receive voice signals and data signals at the first telephone interface, to block data signals from being transmitted via the second telephone interface and optionally to transmit voice signals via the second telephone interface.
