Calling Party Authentication via Preliminary Cryptographic Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often avoid answering calls from unrecognized numbers, and in multi-party calls, verifying the identity of the calling party can be challenging, leading to coordination issues and unnecessary delays.
Innovation Solution
A system and method for authenticating calling parties during voice and data communications, allowing users to exchange documents and acknowledgments seamlessly across multiple devices, and providing authentication mechanisms for verifying the identity of calling parties through cryptographic keys and session-specific codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users answer calls from unrecognized numbers, then communication efficiency is improved, but security risk increases
Solution Approach 1:
The system performs preliminary authentication of the calling party's identity before the called party answers the call. Authentication credentials are verified in advance, and only authenticated callers are allowed to complete the call connection, eliminating the need for users to manually verify unfamiliar numbers.
Solution Approach 2:
An intermediary authentication system is introduced between the caller and the called party. This intermediary service verifies the caller's identity credentials and mediates the call connection, providing security assurance without preventing legitimate communications.
2Reliability
If multi-party call authentication is implemented, then calling party identity verification is improved, but system complexity increases
Solution Approach 1:
The authentication system is designed to handle both single-party and multi-party calls using the same authentication mechanisms. The system provides universal authentication functionality that adapts to different call types without requiring separate complex systems for each scenario.
Solution Approach 2:
The system uses cryptographic tokens and session codes that can be replicated and transmitted across multiple devices. These digital credentials serve as verifiable copies of authentication status, allowing identity verification without complex real-time coordination between all parties.
3Reliability
If cryptographic authentication is used, then security is improved, but processing time increases
Solution Approach 1:
Cryptographic authentication credentials are generated and verified in advance before the actual call connection is established. The computationally intensive cryptographic operations are performed preliminarily, so that when the call needs to be connected, the authentication is already complete and only simple verification is needed.
Solution Approach 2:
The time-consuming cryptographic verification process is extracted and performed separately from the call connection process. Authentication credentials are validated in advance, and only the essential connection signaling remains during the actual call setup, minimizing processing time delays.

AI summary
Methods and systems described in this disclosure are directed to authentication of calling parties. The authentication of calling parties applies to simultaneous voice and/or data communications with multiple parties over multiple electronic mediums including a variety of electronic devices. A user can continue to maintain a data exchange session with a representative of an entity offering the goods or services of interest to the user across more than one user device. In some embodiments, a user can invite other parties in a multi-party call involving the user and the representative. Various embodiments for multi-party and multi-device authentication mechanisms are described herein. In some embodiments, the system calculates an estimated call waiting time for a user to speak with the representative.
