Peer-to-Peer Content Transfer for Secure Smartphone Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphones, which store sensitive information and can be expensive, pose risks of identity theft and financial loss if stolen or damaged, particularly when users hand them to untrusted individuals for picture-taking or application use without ensuring secure data transfer.
Innovation Solution
A method and system for establishing a peer-to-peer communication channel that allows content created on one device to be automatically shared with another device while preventing access to the content on the original device, using a camera application or other applications, by either deleting the content or writing it directly to a media stream without storage, and enabling sharing via social media or multiple connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users hand their smartphone to untrusted individuals for picture-taking or application use, then the ease of operation is improved, but the security and risk of theft or damage worsens
Solution Approach 1:
The patent extracts the harmful element (sensitive data on the smartphone) from the system by automatically transferring created content directly to the user's device through peer-to-peer communication, preventing the data from remaining on the borrowed device where it could be stolen or accessed unauthorizedly
Solution Approach 2:
The patent introduces an intermediary mechanism (peer-to-peer communication channel with automatic content transfer) that enables the smartphone to share its capabilities with untrusted individuals while maintaining security through direct data transmission to the user's device, eliminating the need for physical possession transfer
2Ease of operation
If content is stored on the second computing device for sharing, then the ease of operation is improved, but the security and access control worsens
Solution Approach 1:
The patent extracts the content directly from the second computing device through peer-to-peer communication channels, transferring it immediately to the first computing device without allowing it to be stored or cached on the second device, thereby eliminating the window of vulnerability to unauthorized access
Solution Approach 2:
The patent creates a direct copy of the content through peer-to-peer transmission from the second computing device to the first computing device, where the original content remains on the second device but inaccessible copies are distributed to authorized recipients only
3Productivity
If automatic content transfer is implemented, then the productivity is improved, but the device complexity worsens
Solution Approach 1:
The patent implements self-service automation where the system automatically establishes peer-to-peer communication channels, transfers content without user intervention, and manages the complexity internally while presenting a simple interface to users, thereby achieving high productivity without increasing perceived device complexity
Data Source
AI summary
A method, computer program product, and computer system for receiving, at a second computing device by a first computing device, an invitation to establish a peer to peer communication channel. The second computing device may accept the invitation. An application may be utilized on the second computing device. Content created by the application on the second computing device may be automatically shared with the first computing device, via the peer to peer communication channel, based upon utilization of the application on the second computing device. Access to the content may be prevented on the second computing device.
