Remote Server Mediator for Secure Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional telephony connections, especially in customer service call centers, are inefficient due to repeated authentication requirements and long hold times, and the 'call back' feature raises security concerns with potential malicious spoofing.
Innovation Solution
A method and apparatus that utilize a remote server to manage unique identifiers and session IDs for secure information exchange between endpoints, allowing user information to be stored and retrieved securely without re-authentication during call transfers and providing secure communication through a trusted server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user information is stored on the customer service call center system, then authentication efficiency is improved during call transfers, but security risk increases due to potential system breaches
Solution Approach 1:
A trusted remote server acts as an intermediary between the customer service call center and users. The server stores encrypted user information and provides it to authorized agents through secure sessions, eliminating the need for the call center to directly store sensitive data while maintaining authentication efficiency during call transfers.
Solution Approach 2:
The solution moves authentication data management from the traditional telephony domain to a separate data network domain. By establishing independent data connections between users, agents, and the remote server, the system separates authentication functions from voice communications, improving both security and efficiency.
2Ease of operation
If call back feature is implemented, then user convenience is improved by allowing hang up and later callback, but security vulnerability increases due to phone number spoofing
Solution Approach 1:
The trusted remote server serves as a mediator that verifies the identity of incoming callback requests. When a user requests a callback, the server stores the request and later initiates the call through verified channels, preventing malicious spoofing while maintaining user convenience.
Solution Approach 2:
The system performs preliminary authentication when the user initially contacts the call center. The user's identity is verified and stored in a secure session on the remote server, so that when the callback occurs later, the pre-established trust relationship eliminates the need for re-authentication while preventing impostors.
3Device complexity
If user information is transmitted over the telephony connection, then communication simplicity is maintained, but security risk increases due to potential interception
Solution Approach 1:
The system establishes separate communication dimensions: voice communications continue over the traditional telephony network while authentication data transmissions occur over secure data network connections. This separation allows each channel to be optimized for its intended purpose without compromising security.
Solution Approach 2:
The remote server acts as a secure intermediary that handles all authentication data transmissions. Users and agents communicate authentication information with the server through encrypted data connections rather than directly with each other over telephony channels, eliminating interception risks while maintaining communication simplicity.
Data Source
AI summary
A method, apparatus, and system are provided for sharing data between devices. As an example, a method for exchanging information between a phone and at least one other device includes: obtaining from a remote server a unique identifier that uniquely identifies the phone; establishing a session ID (identifier) between the phone and the other device via first communication channel; and communicating data from the phone to the remote server via a second communication channel along with the session ID, wherein the other device is configured to access the data from the remote server using the session ID.
