Solution Overview

Problem

In multi-terminal cooperative working scenarios, there is a risk of unauthorized disclosure of cooperative working information due to the lack of secure mechanisms for managing recording and playback processes across diverse terminal devices, especially since terminals may not be under a single user's control and may not have installed recording software.

Innovation Solution

A method and apparatus for secure multi-terminal cooperative working that involves determining a security mechanism to store cooperative working information in a secure folder, preventing access by processes other than the cooperative working process, and using NFC or two-dimensional code technologies for network construction, along with signal strength and distance detection to ensure secure data handling and deletion when leaving the cooperative area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual checking of recording software installation is performed on each terminal, then security of cooperative working information is improved, but user privacy is invaded and operation complexity increases

Engineering Contradiction:
Improvesecurity of cooperative working informationVSAvoiduser privacy invasion and operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The terminal device performs self-verification by detecting whether it is currently participating in cooperative working through local process identification, eliminating the need for manual external checking and respecting user privacy while ensuring security

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system establishes a feedback mechanism where the terminal device automatically reports its participation status in cooperative working to the controlling device, enabling automated security verification without manual intervention and reducing operational complexity

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If recording software is installed on a terminal, then capability for cooperative working is improved, but it does not guarantee that the user has recorded cooperative working information

Engineering Contradiction:
Improvecapability for cooperative workingVSAvoidguarantee of information recording
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The terminal device provides feedback by reporting its current participation status in cooperative working processes, allowing the controlling device to verify both software installation and active usage, thereby ensuring reliability that recorded information actually exists

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary verification by checking whether the terminal device is currently participating in cooperative working before allowing access to cooperative working information, preventing access to non-existent or unauthorized recorded information

Inventive Principle:
Principle #10Preliminary action

3Reliability

If cooperative working information is stored in secure folders with access restrictions, then security is improved, but device complexity increases

Engineering Contradiction:
Improvesecurity of cooperative working informationVSAvoidsecure folder management system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The controlling device utilizes existing universal process identification and permission management mechanisms in the terminal device to achieve secure folder management, avoiding the need for separate complex security systems while maintaining security effectiveness

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the terminal device's existing process identification mechanism as an intermediary to verify cooperative working participation status, simplifying the security verification process without requiring additional complex authentication systems

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This application provides a method for secure multi-terminal cooperative working, applied to a network on which a plurality of terminal devices perform cooperative playing and/or cooperative recording, where the plurality of terminal devices include a first terminal device. The method includes: when the first terminal device accesses the network, determining, by the first terminal device, a security mechanism; obtaining, by the first terminal device, cooperative working information, where the cooperative working information is information played and/or recorded by the plurality of terminal devices; and performing, by the first terminal device, security processing on the cooperative working information based on the security mechanism, where the security mechanism is used to prohibit a process other than a cooperative working process from accessing the cooperative working information. After obtaining the cooperative working information, the first terminal device performs security processing on the cooperative working information based on the security mechanism, so that a process other than the cooperative working process cannot access the cooperative working information, thereby ensuring security of the cooperative working information.
