Mobile Account Data Switching via Wireless Key Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication devices require time-consuming full backup/restore operations and wired connections for switching user account data between devices, necessitating third-party involvement and lacking secure encryption/decryption key transfer and preservation of device-specific settings.
Innovation Solution
Implementing a method where a source mobile device establishes a short-range wireless transceiver session with a target device to transfer user account data, including encryption/decryption keys, enabling the target device to maintain data synchronization with a host server, and using removable memory cards for data transfer, allowing end-users to switch accounts on-the-fly without third-party assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full backup/restore operation via desktop manager is used, then user account data can be transferred between devices, but the process is time-consuming and requires wired connections
Solution Approach 1:
The patent extracts the essential data transfer functionality from the complex desktop manager backup/restore process. It isolates only the necessary user account data and synchronization information, transferring them directly between devices via wireless connection, eliminating the need for full system backup and restore operations.
Solution Approach 2:
The patent replaces the mechanical wired connection required by desktop manager with a wireless communication system. The source and target devices establish a wireless connection to transfer user account data, eliminating the need for physical cable connections and external computer equipment.
2Reliability
If full backup/restore operation via desktop manager is used, then user account data can be transferred between devices, but third-party involvement and wired connections are required
Solution Approach 1:
The patent enables the mobile devices to perform the data transfer operation independently without requiring external desktop manager software or third-party computer involvement. The source and target devices directly communicate with each other wirelessly, making the system self-sufficient and easier to operate.
Solution Approach 2:
The patent creates a universal data transfer mechanism that works between any compatible mobile devices without requiring specific external software or equipment. The wireless communication protocol and data format are designed to be device-agnostic, enabling broad compatibility and eliminating third-party dependencies.
3Reliability
If standard data transfer methods are used, then data can be moved between devices, but encryption/decryption keys are not securely transferred and device-specific settings are not preserved
Solution Approach 1:
The patent performs preliminary identification and extraction of critical data elements including encryption/decryption keys and device-specific settings before the actual data transfer. These essential components are packaged together with user account data and transferred in a single operation, ensuring nothing is lost or left behind.
Solution Approach 2:
The patent introduces a data synchronization server as an intermediary that facilitates secure key and settings transfer. The server acts as a trusted mediator that receives, verifies, and forwards encryption keys and device-specific configurations to the target device, ensuring secure and complete information transfer.
Data Source
AI summary
A host server is configured to switch communications associated with an account between first and second mobile devices. The server stores a mapping of the account to a first PIN which identifies the first mobile device, and communicates messages via a wireless network based on the stored mapping using the first PIN for data synchronization therebetween. The server then receives a request for device switching. In response, the server switches the mapping of the account to a second PIN which identifies a second mobile device, and communicates messages via the wireless network based on the switched stored mapping using the second PIN for data synchronization therebetween. The mapping of the account to the first PIN may be maintained even after switching the stored mapping to the second PIN, for a subsequent request for switching back to the first mobile device for the account.
