Wireless Mobile Device Backup via Smart Card Reader
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices lack the ability for on-the-fly backup and restore of critical data, especially when users are away from their personal computers, leading to inaccessible data and disrupted wireless services due to corruption or erasure of service data and encryption keys.
Innovation Solution
A mobile communications device system that includes a smart card reader with a short-range communications system, enabling automatic detection of corrupted data and provisioning through a wireless link to restore service books and encryption keys, allowing for backup and restore operations without the need for a physical connection to a desktop computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional mobile devices synchronize with a personal computer through a cradle or wired connection, then data can be backed up and restored, but the user cannot access data or restore services when away from the computer
Solution Approach 1:
The patent introduces a portable backup device as an intermediary between the mobile device and the user. This device includes a processor, memory for storing backup data, and a wireless communication interface. The portable device enables users to backup and restore data wirelessly without requiring connection to a personal computer, thus resolving the contradiction between backup capability and mobile accessibility.
2Reliability
If service data and encryption keys are stored on the mobile device, then wireless services can operate, but data becomes vulnerable to corruption and inaccessibility when the device is away from synchronization points
Solution Approach 1:
The patent implements automatic backup functionality that creates redundant copies of service data and encryption keys before potential corruption occurs. The portable device continuously or periodically backs up critical data to its own memory storage, ensuring that even if the mobile device's data becomes corrupted or erased, users can restore services from the portable backup device without requiring access to a personal computer.
3Reliability
If users must contact a system administrator to retrieve passwords or repair instructions, then security is maintained, but time and operational efficiency are reduced
Solution Approach 1:
The patent enables users to perform data restoration independently through the portable backup device. When data corruption is detected, the device automatically or semi-automatically restores service data and encryption keys from its stored backups using wireless communication. This self-service capability eliminates the need for users to contact system administrators for password retrieval or repair instructions, thereby reducing restoration time while maintaining security through controlled access to the backup device.
