Knowledge Authentication Guardrail for Posthumous Therapy Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional therapeutic interventions lack effective mechanisms for engaging with deceased loved ones or unresolved conflicts, and there is a need for secure and private sharing of therapeutic journeys, ensuring privacy, security, and adherence to user wishes, particularly in the context of posthumous access.

Innovation Solution

An AI-powered avatar module within a virtual environment allows users to interact with deceased loved ones or individuals with unresolved conflicts, with a documentation module for recording experiences, a selective sharing module for secure access control, and a knowledge authentication guardrail to verify authenticity using interactive zero-knowledge proofs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional therapeutic interventions are used, then basic therapeutic support is provided, but effective engagement with deceased loved ones or unresolved conflicts is not achieved

Engineering Contradiction:

Improveability to engage with deceased loved onesVSAvoideffectiveness of therapeutic intervention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system creates a virtual copy or representation of deceased loved ones through AI-powered avatars, allowing users to interact with and resolve conflicts related to these individuals without requiring the actual presence of the deceased persons

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces an intermediary virtual environment and AI avatar system that mediates between the user and deceased loved ones or unresolved conflicts, enabling therapeutic engagement that would otherwise be impossible

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If therapeutic journeys are shared with trusted individuals, then emotional support is enhanced, but privacy and security concerns increase

Engineering Contradiction:

Improveselective sharing capabilityVSAvoidprivacy and security risks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system implements differentiated access control where different portions of the therapeutic journey are shared with different trusted individuals based on user-defined permissions, allowing selective disclosure of sensitive information while maintaining overall privacy

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Users pre-configure access control policies and trusted individual designations before sharing their therapeutic journeys, establishing privacy and security parameters in advance to prevent unauthorized access

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If posthumous access control is implemented, then user wishes are respected, but system complexity increases

Engineering Contradiction:

Improveposthumous access controlVSAvoidaccess control mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Users establish their posthumous access control preferences, designate trusted individuals, and configure sharing parameters while still alive, before any death event occurs. This preliminary configuration simplifies the posthumous access process by having all decisions pre-made

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically executes the pre-configured access control policies upon detection of the user's death, without requiring complex real-time decision-making or intervention, thereby reducing operational complexity while maintaining sophisticated control

Inventive Principle:

Principle #25Self-service

4Reliability

If authentication mechanisms are added to verify trusted individuals, then security is improved, but ease of operation decreases

Engineering Contradiction:

Improveauthentication securityVSAvoidaccess granting simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system creates a virtual copy of the user's knowledge or memories that serves as an authentication mechanism, where the AI avatar itself becomes the verification tool rather than requiring separate complex authentication protocols

Inventive Principle:

Principle #26Copying
