Trusted Group Device Coordination for Seamless SSO
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corporate employees face distractions and inefficiencies due to devices locking or unlocking independently, disrupting workflow and access to information across multiple devices.
Innovation Solution
A trusted group system where devices communicate securely to coordinate lock/unlock states, using SIP, XML, or other signaling protocols to establish a secure connection and manage device activities collectively, ensuring all devices remain available or locked based on user presence and activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices independently lock/unlock based on local inactivity detection, then each device secures its own data, but user access is disrupted and productivity decreases
Solution Approach 1:
The patent merges the lock/unlock control of multiple devices into a coordinated system. Devices in a trusted group share lock/unlock states through inter-device communication, so when one device locks due to inactivity, other devices in the group are notified and can coordinate their locking behavior, preventing fragmented and disruptive locking patterns across the user's device ecosystem
Solution Approach 2:
The system implements feedback mechanisms where devices continuously report their operational state and inactivity conditions to each other. When a device detects inactivity and prepares to lock, it first queries other devices in the trusted group to see if they are also inactive or actively in use, allowing the locking decision to be informed by real-time feedback from the entire device group rather than acting in isolation
2Productivity
If devices communicate continuously to coordinate lock/unlock states, then device availability is optimized, but network bandwidth and processing resources are consumed
Solution Approach 1:
The communication between devices is made dynamic rather than static. Devices only establish and maintain communication channels when necessary - specifically when inactivity events occur or when devices join/leave the trusted group. During normal active operation, devices do not continuously communicate, reducing unnecessary network resource consumption while still maintaining coordination capability when needed
3Reliability
If authentication information is required for every device access, then security is maintained, but access speed is reduced
Solution Approach 1:
The system performs preliminary authentication actions during device initialization and trusted group formation. Once devices are authenticated and joined to a trusted group, their authentication status is cached and communicated to other devices. When a device needs to lock or unlock, it can query the cached authentication state of other devices without requiring re-authentication, significantly reducing access time while maintaining security

AI summary
A system creates a trusted group of devices for single sign on. The trusted group is a set of two or more devices which can communicate securely to exchange information about the states of the devices. The two or more devices can arrange or establish the trusted group through the exchange of credentials or authentication information. After the establishment of the trusted group, the two or more devices may communicate through a secure connection established between the members of the trusted group. Each device may then execute normally and may encounter events that change the status of the device. Information about the locking or unlocking of the computer can be exchanged with the other members of the trusted group and the other members may also lock or unlock in concert.
