Segregated Data Backup via Encrypted Subset Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are reluctant to back up their data to remote devices due to concerns about privacy and unauthorized access, despite the importance of data redundancy, as existing solutions do not adequately ensure the security and privacy of stored data.
Innovation Solution
The system encrypts data items, divides them into encrypted subset data items, and randomly distributes these across multiple remote electronic devices, with only the primary device maintaining the mapping of where each subset is stored, ensuring that no single device can decrypt the data without all pieces, thus maintaining high privacy and security levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is backed up to remote devices, then data redundancy and accessibility are improved, but data security and privacy are compromised
Solution Approach 1:
The patent divides encrypted data into multiple encrypted subsets and distributes them across different remote devices. No single device contains the complete data, making unauthorized access ineffective even if one device is compromised. This directly resolves the contradiction by maintaining redundancy while enhancing security through distribution.
Solution Approach 2:
The patent introduces a secure enclave as an intermediary layer between the user device and remote storage devices. The secure enclave manages encryption keys and controls access to encrypted subsets, acting as a mediator that enables remote backup while preventing unauthorized access. This intermediary mechanism resolves the trust issue inherent in remote storage.
2Object-affected harmful factors
If data is encrypted and divided into subsets, then data security is improved, but system complexity increases
Solution Approach 1:
The patent implements automatic encryption and subset distribution mechanisms that operate without requiring user intervention. The system self-manages the complex tasks of encryption, division, distribution, and reconstruction, reducing the perceived complexity for users while maintaining high security standards. This automation resolves the contradiction by handling complexity internally while presenting a simple interface.
3Object-affected harmful factors
If data is stored locally, then data security is maintained, but data accessibility and redundancy are limited
Solution Approach 1:
The patent transitions data storage from a single location (local device) to multiple distributed locations (remote devices), adding a spatial dimension to storage architecture. This dimensional change enables both security through distribution and accessibility through multiple access points, resolving the contradiction between security and accessibility by operating in a multi-dimensional storage space.

AI summary
A method in an electronic device designates, with one or more processors of the electronic device, at least one data item stored within a memory of the electronic device for storage in a plurality of remote electronic devices. The method encrypts, with the one or more processors, the at least one data item to create at least one encrypted data item. The method divides, with the one or more processors, the at least one encrypted data item into a plurality of encrypted subset data items. The method then delivers, with a communication device, at least a first encrypted subset data item from the plurality of encrypted subset data items to a first remote electronic device and at least a second subset data item from the plurality of encrypted subset data items to a second remote electronic device.
