Secure Multi-Terminal Cooperative Working via Process Identification
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
3Reliability
If cooperative working information is stored in secure folders with access restrictions, then security is improved, but device complexity increases
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
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

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.
