Wireless Mobile Device Data Retrieval via Server Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless mobile devices are prone to loss, theft, and data security risks due to their portable nature, as they increasingly store sensitive information, necessitating effective data protection and retrieval solutions.
Innovation Solution
A system that registers wireless mobile devices for data retrieval services using a server with secure key exchange and Trusted Platform Module (TPM) encryption, allowing users to remotely backup and restore data across different devices via wireless communication, even when the original device is unavailable or stolen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless mobile devices are made portable for ease of use, then ease of operation is improved, but security and data protection deteriorate due to increased risk of loss and theft
Solution Approach 1:
The system creates a remote copy of the mobile device's data storage capability through the server. When the original device is lost or stolen, the server maintains a copy of the data and enables restoration to a new device, effectively replacing the physical device without requiring direct access to the original.
Solution Approach 2:
The server acts as an intermediary between the mobile device and the user's data. It provides a secure remote interface that allows data access and transfer without physical possession of the original device, enabling users to retrieve data wirelessly through authenticated requests.
2Speed
If data is stored locally on the mobile device for fast access, then speed is improved, but loss of information increases when the device is lost or stolen
Solution Approach 1:
The system performs preliminary data backup to the server before the device is potentially lost or stolen. This advance preparation ensures that data is already secured remotely and can be immediately restored to a new device without requiring physical access to the original device's storage.
Solution Approach 2:
The server maintains a remote copy of the device's data storage, allowing users to access and restore data without needing the physical device. This copy mechanism ensures data availability even when the original device is unavailable.
3Reliability
If remote data retrieval is enabled to protect against device loss, then reliability is improved, but device complexity increases due to additional security mechanisms
Solution Approach 1:
The complex security and data management functions are extracted from the mobile device and transferred to the server. The device only needs basic wireless communication capabilities, while the server handles authentication, data storage, retrieval, and device identification, significantly reducing the complexity requirements for the mobile device itself.
Data Source
AI summary
A system comprises a processing device including a storage device. The system further comprises a wireless mobile device (“WMD”) in wireless communication with the processing device. The processing device registers the WMD and stores the registration in the system memory, receives a request for retrieval of data located in the WMD, authenticates the request based on the registration, and retrieves the data wirelessly based on the authentication.
