Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional peer-to-peer data sharing methods for mobile devices lack security and selectivity, leading to inefficiencies, privacy risks, and inadequate control over data exchange, particularly in third-party data sharing scenarios.
Innovation Solution
A system and method for secure peer-to-peer data sharing using encrypted channels, where a cloud-based system facilitates data access through authorization tokens, enabling selective data exchange with granular control and efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional peer-to-peer data sharing methods are used, then data exchange is simple and direct, but security and privacy protection are insufficient
Solution Approach 1:
The patent introduces a cloud-based system as an intermediary between mobile devices to manage data sharing. The cloud system receives sharing requests, generates authorization tokens, and coordinates the data exchange process, thereby providing security and control without requiring complex encryption implementations on individual mobile devices. This resolves the contradiction by centralizing security functions in the cloud while keeping mobile device operations simple.
2Object-affected harmful factors
If selective data sharing with granular control is implemented, then privacy protection is improved, but the complexity of data sharing protocols increases
Solution Approach 1:
The patent segments data into different data types (e.g., photos, contacts, messages) and allows users to select specific data types for sharing through structured protocols. The cloud system processes these segmented data type selections and generates corresponding authorization tokens, enabling granular privacy control without requiring complex implementation on mobile devices. The segmentation approach simplifies the protocol by using standardized data type categories.
Solution Approach 2:
The patent uses parameter-based authorization tokens that encode sharing permissions, data types, and time limits. By changing the parameters within the token structure rather than creating complex protocol messages, the system achieves granular control with relatively simple protocol exchanges. The token parameters allow the cloud system to enforce detailed sharing policies through straightforward validation logic.
3Reliability
If encrypted channels are used for data transmission, then security is enhanced, but processing overhead and transmission efficiency are reduced
Solution Approach 1:
The patent performs encryption and authorization setup in advance through the cloud-based system before actual data transmission between mobile devices. Authorization tokens are generated and validated beforehand, and encryption keys are established through the cloud intermediary. This preliminary action eliminates the need for real-time complex cryptographic operations during data transmission, thereby maintaining security while improving transmission efficiency.
Data Source
AI summary
System and methods are disclosed that enable data sharing across networks, including peer-to-peer sharing of content over wireless networks using peer mobile devices. A database may store content associated with a first peer mobile device. A request from a requester peer mobile device for content associated with a user of the first peer mobile device may be received at a server. The encrypted request is transmitted by the server to the first peer mobile device which may decrypt the request. An authorization token may be transmitted by the first peer mobile device to the server which may then enable the requesting peer mobile device to access the requested content, which may be accessed from the first peer mobile device and/or a cloud storage system.
