Device Switching Service Using Temporary Cloud Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of switching from one cellular phone to another is time-consuming and insecure, often requiring up to an hour to transfer data and posing risks to personal information due to existing security issues and inefficiencies in data backup and restore processes.
Innovation Solution
A method involving temporary cloud storage set up by the service provider for users to back up personal data from their old phone, which is then transferred to the new phone in two parts, ensuring privacy and security by preventing service provider access to the data and permanently deleting it once transferred, significantly reducing transfer time by up to 75-80%.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional direct data transfer method is used between phones, then data transfer can be completed, but the process takes up to an hour and exposes user data to security risks
Solution Approach 1:
The patent introduces cloud storage as an intermediary between the old and new devices. User data is first uploaded to the cloud storage service, then downloaded to the new device. This intermediary approach eliminates direct peer-to-peer transfer vulnerabilities and reduces transfer time by enabling parallel upload/download operations and utilizing high-speed cloud infrastructure.
2Productivity
If cloud storage is used for data transfer, then transfer time is reduced and security is improved, but service provider gains potential access to user data
Solution Approach 1:
The patent segments the data transfer process into distinct phases: upload to cloud storage, processing/transfer, and download to new device. The cloud storage service provider only temporarily holds data during the transfer window, not permanently. This segmentation limits the provider's exposure and opportunity for data access while maintaining transfer efficiency.
Solution Approach 2:
The system performs preliminary actions by establishing secure encryption protocols before data is uploaded to cloud storage. Data is encrypted client-side before transmission, so even if the service provider could access the storage, the data remains protected. This preliminary security measure enables efficient cloud-based transfer without compromising user privacy.
3Ease of operation
If manual data transfer process is used, then user has control over the process, but the process is tedious and time-consuming requiring user presence for up to an hour
Solution Approach 1:
The patent implements self-service capabilities where the system automatically manages the data transfer process. Once the user initiates the transfer and selects cloud storage, the system autonomously handles upload, transfer, and download operations without requiring continuous user presence or manual intervention. The user simply needs to be available at the beginning and end of the process, reducing time investment from up to an hour to minimal setup and confirmation steps.

AI summary
A device switching technique that can be used when a user switches from a first cell phone to a second cell phone is described, wherein a phone provider detects an event indicating that a device switch is imminent and sets up temporary storage associated with a first device. At the user's convenience, the user performs a data transfer process to transfer a portion of user data from the first device to the temporary storage. When the user receives the second device, such as in a phone store, remaining user data is transferred from the first device to the second device, thereby decreasing the amount of time necessary to set up the second device.
