IVR Response Data Storage and Transmission via Smart Card Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive Voice Response (IVR) systems face challenges in securely storing and transmitting sensitive response data, such as credit card numbers and account information, during voice calls, as existing solutions lack robust security measures and efficient data management.
Innovation Solution
A method and device that store response data in memory within electronic devices, allowing for secure retrieval and transmission to IVR systems through voice communications interfaces, using DTMF tones or speech recognition, with optional content protection and smart card verification for added security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If response data is stored in memory during IVR sessions, then data transmission efficiency is improved, but security risks increase due to potential unauthorized access
Solution Approach 1:
The patent introduces smart card verification as an intermediary security layer between the user and the stored response data. The smart card acts as a mediator that must be authenticated before allowing access to the memory-containing device, thus preventing unauthorized access while maintaining efficient data transmission during authorized IVR sessions.
Solution Approach 2:
The system performs preliminary security verification by requiring smart card authentication before enabling access to the response data stored in memory. This preliminary action ensures that only authorized users can retrieve and transmit data, addressing the security concern before the actual data transmission occurs during the IVR session.
2Reliability
If content protection measures are implemented, then security is improved, but device complexity increases
Solution Approach 1:
The smart card serves as an external intermediary security module that offloads the complexity of content protection from the main electronic device. By using a separate smart card system for verification, the patent enhances security while minimizing the increase in overall device complexity, as the core device only needs to interface with the smart card rather than implementing complex protection algorithms internally.
3Reliability
If multiple security verification methods are used, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The smart card verification system operates as a self-service authentication mechanism where the user simply presents their smart card to the device, and the system automatically verifies it without requiring manual intervention or complex user actions. This self-service approach maintains ease of operation while implementing robust security verification.

AI summary
A method and electronic device for storing and transmitting response data in an interactive voice response (IVR) system session are provided. Response data, such as a credit card number, system access code or password may be stored in the device. During an IVR session, the response data may be selected, retrieved and transmitted to respond to an IVR request. Content protection may be used to control access to the response data and to allow access to the response data if an IVR session is established.
