Temporary File System for Secure Device Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient methods for securely and temporarily sharing data between electronic devices while ensuring privacy and security, particularly in scenarios where direct communication is preferred without intermediaries.
Innovation Solution
A method where a first electronic device selects a second device for temporary file storage, performs an authentication handshake, and creates a secure, separate temporary file system on the second device for data from the first device, which is accessible during a guest session and deleted when specific criteria are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is shared between electronic devices, then data accessibility is improved, but security and privacy are worsened
Solution Approach 1:
The patent creates a separate temporary file system on the second device that is logically segmented from the host device's main file system. This segmented structure allows data from the first device to be stored and accessed temporarily without integrating with the host device's permanent storage, thereby maintaining security and privacy while enabling data accessibility during the session.
Solution Approach 2:
The temporary file system acts as an intermediary layer between the first device and the host device's file system. It provides a secure intermediate storage space that facilitates data transfer and accessibility during the session while preventing direct integration with the host device's permanent storage, thus addressing security concerns.
2Adaptability or versatility
If a temporary file system is created on the second device, then data sharing capability is improved, but device complexity is worsened
Solution Approach 1:
The temporary file system is designed to be a universal solution that can accommodate data from multiple first devices and support various data types. It provides a standardized interface and storage mechanism that enables data sharing across different device types and scenarios, enhancing versatility without requiring device-specific complex implementations.
Solution Approach 2:
The temporary file system is designed as a transient, disposable structure that is created for a specific session and automatically deleted when the session ends. This short-lived nature simplifies the overall system design by avoiding the need for complex permanent storage management mechanisms, while still providing robust data sharing capability during its active period.
3Reliability
If authentication handshake is performed, then security is improved, but time consumption is worsened
Solution Approach 1:
The authentication handshake is performed preliminarily before data transfer begins, establishing security credentials and trust relationships in advance. This preliminary authentication step ensures security is established before any data is shared, while the efficiency of the handshake protocol minimizes time consumption during the actual data transfer operation.

AI summary
A plurality of devices in a system discover one another and a first electronic device selects a second electronic device from amongst a plurality of devices to coordinate file storage. In some embodiments, the first electronic device and the second electronic device perform an authentication handshake. After performing the authentication handshake, the first electronic device transmits first data to the second electronic device. In some embodiments, the second electronic device operates using a temporary file system that includes the first data. In accordance with a determination that one or more criteria are satisfied, the second electronic device ceases operating using the temporary file system and deletes at least a portion of the temporary file system and/or first data.
