Mobile Device Data Sharing via Root of Trust Status Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems for mobile devices face challenges in efficient data sharing among multiple devices, requiring laborious manual pairing, lack of trust between devices, and inefficient decision-making on data usage and distribution.
Innovation Solution
Implementing a system where mobile devices share status information and use a Root of Trust (RoT) device for secure communication, enabling automatic device pairing and data forwarding based on shared status information and user context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pairing is used for device connection, then device connectivity is established, but the process becomes laborious and time-consuming
Solution Approach 1:
The system enables devices to automatically pair with each other using shared status information and a common trust relationship established through the Root of Trust device. Devices self-configure connections without manual user intervention, eliminating the laborious manual pairing process while maintaining secure connectivity.
Solution Approach 2:
The Root of Trust device performs preliminary authentication and trust establishment with all devices in the group before actual data sharing begins. This preliminary action creates pre-configured trust relationships that enable immediate automatic pairing when devices need to communicate, eliminating the need for time-consuming pairing procedures.
2Productivity
If devices operate independently without shared status information, then device autonomy is maintained, but efficient data sharing and coordination among devices is prevented
Solution Approach 1:
The Root of Trust device serves as an intermediary that manages shared status information for all devices in the group. Rather than requiring complex peer-to-peer coordination mechanisms between all devices, the Root of Trust mediates information sharing, simplifying the system architecture while enabling efficient data sharing through centralized status management.
Solution Approach 2:
The shared status information structure serves multiple functions simultaneously: it tracks device connectivity states, manages trust relationships, coordinates data sharing decisions, and enables automatic pairing. This universal status mechanism replaces multiple separate coordination systems, reducing overall device complexity while improving productivity.
3Adaptability or versatility
If data is shared among all devices in the group, then data accessibility is improved, but security and trust management becomes more challenging
Solution Approach 1:
The Root of Trust device acts as a security intermediary that verifies and manages trust relationships for all data sharing operations. It mediates between the need for broad data accessibility and security requirements by centrally managing authentication and authorization, ensuring that only trusted devices can access shared data while maintaining versatile accessibility across the device group.
Solution Approach 2:
The system implements differentiated access control where each device receives data sharing permissions tailored to its specific trust level and functional requirements. Rather than uniform data access for all devices, the Root of Trust configures local quality of access rights based on individual device characteristics, maintaining both security and adaptability.

AI summary
Described are techniques for sharing data among a group of mobile devices that are registered to the same user. In some instances, the shared data is sensor data captured by a mobile device or media content being processed by the mobile device. The mobile devices in the group are configured to wirelessly communicate with each other and to share status information. Using the status information, the mobile devices can keep each other updated as to the operational status of each individual mobile device and, in some aspects, the status of a mobile device with respect to the user. The sensor data or media content can be forwarded to a different mobile device in response to a determination made based on the status information. For instance, forwarding can be based on a rule that specifies one or more conditions relating to the status of a mobile device and/or user status.
