Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication systems lack integration across different modes, leading to manual data transfer and limitations for remote and mobile workers, especially in regulated industries where call recordings are required for compliance.

Innovation Solution

Implementing a unified communications as a service (UCaaS) platform integrated with distributed transaction ledgers for call recording authentication, enabling secure, automated, and compliant call recording management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If separate communication services are implemented by different service providers, then each service can be optimized independently, but information must be manually passed between services and system integration is lacking

Engineering Contradiction:

ImproveService implementation independenceVSAvoidSystem integration complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges multiple separate communication services (telephony, email, messaging) into a unified UCaaS platform that integrates these services over a network, eliminating the need for manual information transfer between separate systems while maintaining the ability to implement each service independently through modular service components

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If telephony services are delivered via on-premises systems, then service control is maintained locally, but remote workers and mobile workers cannot reliably access these services

Engineering Contradiction:

ImproveLocal service controlVSAvoidRemote access capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The UCaaS platform provides universal access to telephony services through multiple communication modes (voice calls, video calls, instant messaging, email) that can be accessed from any location via network connection, while maintaining centralized service control that replaces the need for local on-premises systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If call recordings are stored without distributed ledger technology, then storage is simpler, but authentication and verification of call recording integrity is difficult

Engineering Contradiction:

ImproveStorage system simplicityVSAvoidCall recording authentication

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent introduces a distributed transaction ledger as an intermediary system that stores cryptographic hashes and metadata of call recordings, providing an immutable verification mechanism that authenticates call recording integrity without complicating the actual storage of recording files themselves

Inventive Principle:

Principle #24Intermediary (Mediator)

PatentUS20250202880A1Call Recording Authentication Using A Transaction Identifier Stored In A Record Within A Distributed Transaction Ledger

Publication Date: 2025.06.19 ZOOM COMMUNICATIONS INC

AI summary

A call between two or more participants is recorded to generate a call recording. A record of the call recording is stored within a distributed transaction ledger. A transaction identifier associated with the record is stored in the record. At a later time, such as in response to an access request for auditing or an authentication request, the call recording is authenticated based on the transaction identifier. An indication of the authentication is then output, such as for further processing or display.
