Trusted Caller ID Authority Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caller identification data can be spoofed, leading to inaccurate information about the originator of a telephone call, which hampers effective communication and poses risks such as identity theft by allowing fraudulent entities to masquerade as legitimate entities.
Innovation Solution
A system that provides authenticated caller identification through a trusted caller ID authority, where communication devices register and receive authentication objects, such as certificates or tokens, which are verified by a server, ensuring the authenticity of the caller's identity and location, and are displayed on receiving devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If caller identification data is transmitted without authentication, then communication simplicity is maintained, but reliability of caller identity information deteriorates due to spoofing
Solution Approach 1:
A trusted caller ID authority server acts as an intermediary between the caller and recipient. The server receives authentication requests from communication devices, verifies them against registered information, and returns authentication objects (certificates or tokens). This intermediary system ensures caller identity authenticity without requiring direct complex verification between communicating parties, thus improving reliability while managing complexity centrally.
Solution Approach 2:
Communication devices perform preliminary registration with the trusted caller ID authority before actual communication. During registration, devices provide identification information that is verified and stored. This preliminary action ensures that when communication occurs, the authentication process is streamlined, as the device already has pre-verified credentials, balancing reliability requirements with operational simplicity.
2Reliability
If authentication objects are verified for every call, then caller identity reliability is improved, but communication time increases due to verification processes
Solution Approach 1:
Authentication credentials are established in advance during device registration with the trusted caller ID authority. The authentication object (certificate or token) is generated and stored on the device before actual communication occurs. This preliminary authentication setup allows for rapid verification during calls, as the verification process simply checks pre-established credentials rather than performing full identity verification in real-time, thus maintaining reliability while minimizing time loss.

AI summary
A trusted caller ID authority receives registration data from a first communication device. The first communication device is authenticated by the trusted caller ID authority using the registration data and an authentication object is provided to the first communication device. A second communication device receives a call and the authentication object from the first communication device. The second communication device sends a validation request to the trusted caller ID authority that includes the authentication object. Validation information associated with the first communication device is provided to the second communication device. The validation information includes registration and authentication status of the first communication device.
