Solution Overview

Problem

There is a need for secure information transfer in virtual environments, particularly in metaverse scenarios, to address security and privacy concerns arising from emerging technologies.

Innovation Solution

A system that detects sensitive information during real-time communication in a virtual interaction session, initiates a temporary sub-session, records and encrypts the sensitive information, and resumes the session after recording, using automated virtual objects and cloud-based APIs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If real-time communication is maintained continuously in a virtual interaction session, then user interaction efficiency is improved, but security of sensitive information is compromised

Engineering Contradiction:

Improveuser interaction efficiencyVSAvoidsecurity of sensitive information

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The continuous virtual interaction session is segmented into regular interaction segments and temporary sub-sessions. When sensitive information is detected, the system automatically pauses the main session and creates an isolated temporary sub-session for secure information exchange. This segmentation allows the system to maintain overall interaction efficiency while ensuring security during sensitive communications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary detection of sensitive information in real-time during the virtual interaction session. Before sensitive information is fully transmitted, the system proactively initiates a temporary sub-session to secure the communication channel. This preliminary action prevents security breaches while maintaining seamless user interaction.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a temporary sub-session is initiated to secure sensitive information, then information security is improved, but session continuity is interrupted

Engineering Contradiction:

Improveinformation securityVSAvoidsession continuity

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The temporary sub-session is designed to process sensitive information quickly and efficiently. The system rushes through the secure information exchange process by maintaining the user's virtual objects and session context, minimizing the perceived interruption. Once sensitive information is securely transmitted, the system immediately resumes the main session, reducing overall time loss.

Inventive Principle:

Principle #21Skipping (Rushing through)

Solution Approach 2:

The system creates a temporary copy of the virtual interaction environment for the sub-session, including duplicate virtual objects and preserved session state. This copying approach allows the secure information exchange to occur in an isolated environment without permanently disrupting the main session, enabling quick resumption after the sub-session completes.

Inventive Principle:

Principle #26Copying

3Reliability

If sensitive information is recorded and encrypted within a temporary sub-session, then privacy protection is improved, but system complexity increases

Engineering Contradiction:

Improveprivacy protectionVSAvoidsystem architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sensitive information processing functionality is extracted into a separate temporary sub-session module. This extraction isolates the complex encryption and recording operations from the main virtual interaction session, allowing the core session management to remain simple while adding security capabilities through a dedicated, self-contained sub-session system.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The temporary sub-session is nested within the existing virtual interaction session framework. The sub-session utilizes the parent session's infrastructure (user profiles, virtual environment, communication protocols) while adding a layer of security processing. This nesting approach avoids duplicating entire systems and reduces overall complexity by leveraging existing components.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

Systems, computer program products, and methods are described herein for secure information transfer in a virtual environment. The present disclosure is configured to receive, using a first user input device, real-time communication from a first user during a virtual interaction session with a second user in the virtual environment; determine that at least a portion of the real-time communication comprises sensitive information; initiate a temporary sub-session within the virtual interaction session in response to determining that the real-time communication comprises sensitive information, thereby temporarily pausing the virtual interaction session; record the sensitive information within the temporary sub-session; terminate the temporary sub-session in response to recording the sensitive information; and resume the virtual interaction session to continue receiving the real-time communication.
