Solution Overview

Problem

Existing chatbot systems lack the ability to dynamically and securely augment participants in programmatically established sessions, particularly when real-time consent from third parties is required for certain operations, often relying on delayed or unverified approvals.

Innovation Solution

A network-connected computing system detects events during a chatbot session that trigger the inclusion of third parties by generating notifications to their devices, prompting authentication, and securely integrating their chatbot interfaces in real-time, using cryptographic methods to ensure secure and immediate consent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing chatbot systems use delayed or unverified approvals for third-party participation, then the system operation continues without interruption, but security and reliability are compromised

Engineering Contradiction:
ImprovesecurityVSAvoidreal-time consent delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary authentication of third-party participants before allowing them to join the chatbot session. The computing system sends authentication credentials to the third-party device and verifies their identity in advance, ensuring that only authorized participants can access the session. This preliminary verification eliminates security risks while maintaining real-time operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The computing system acts as an intermediary between the chatbot session and third-party participants. It mediates the authentication process by generating and verifying credentials, and controls the admission of third parties to the session. This intermediary role ensures secure real-time participation without requiring the chatbot to directly handle authentication complexities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If existing chatbot systems allow dynamic participant augmentation, then versatility and adaptability improve, but system complexity increases

Engineering Contradiction:
Improveparticipant augmentationVSAvoidsession management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the participant management function into distinct components: the computing system handles authentication and session management, while the third-party device handles local authentication operations. This segmentation allows the chatbot session to dynamically accept new participants without overwhelming the core system with complex management logic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system implements feedback mechanisms where the computing system monitors chatbot sessions for events triggering third-party participation, sends authentication credentials to potential participants, and receives verification results. This continuous feedback loop enables automatic, real-time participant augmentation while maintaining session integrity and reducing manual intervention requirements.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If existing chatbot systems use unverified approvals for third-party access, then ease of operation improves, but reliability deteriorates

Engineering Contradiction:
Improvethird-party accessVSAvoidauthentication verification
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The third-party device performs self-service authentication by receiving credentials from the computing system and verifying its own identity. The device independently validates its authentication status and establishes secure connections without requiring manual verification operators. This self-service approach maintains ease of operation while ensuring reliable authentication through cryptographic verification.

Inventive Principle:
Principle #25Self-service

AI summary

The disclosed exemplary embodiments include computer-implemented systems, apparatuses, and processes that dynamically and securely augment participants in programmatically established chatbot sessions. For example, an apparatus may obtain messaging data generated during a first communications session involving a first device and based on the messaging data, detecting an occurrence of an event that triggers an establishment of a second communications session involving the first device and a second device. The apparatus may generate and transmit, to the second device, notification data causing the second device to validate one or more authentication credentials, and may receive confirmation data indicative of the one or more validated authentication credentials from the second device. Based on the confirmation data, the apparatus may perform operations that establish the second communications session in accordance with at least a portion of the messaging data.
