Peer-to-Peer Data Synchronization Without Central Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face the challenge of maintaining consistent data across multiple devices without a central server, requiring manual updates on each device, which is inefficient and prone to errors, especially for home users lacking access to a central synchronization platform.
Innovation Solution
Implementing a peer-to-peer data synchronization method that allows devices to communicate directly or indirectly over local or wide-area networks, using protocols like SyncML, enabling automatic synchronization of user applications and data across devices without the need for a central server, ensuring that changes on one device are automatically propagated to all connected devices.

Engineering Contradiction Analysis
1Reliability
If a central server is used for data synchronization, then data consistency across devices is improved, but system complexity and cost increase due to requiring server infrastructure
Solution Approach 1:
The patent extracts the synchronization coordination function from a central server and distributes it to peer devices themselves. Each device maintains its own synchronization state and can independently coordinate with other peer devices, eliminating the need for external server infrastructure while maintaining data consistency across the network.
Solution Approach 2:
The patent merges the roles of data storage, synchronization coordination, and peer communication into each individual device. Rather than separating these functions across a client-server architecture, each peer device combines all necessary synchronization capabilities locally, reducing system complexity while ensuring data consistency.
2Device complexity
If manual data updates are performed on each device, then system complexity is reduced, but time consumption and productivity decrease due to repetitive manual entry
Solution Approach 1:
The patent implements self-service synchronization where devices automatically detect data changes, initiate synchronization requests, and update peer devices without user intervention. The synchronization protocol enables devices to autonomously manage data consistency across the network, eliminating repetitive manual updates while maintaining simple system architecture.
3Ease of operation
If peer-to-peer synchronization is implemented, then ease of operation is improved by eliminating manual updates, but device complexity increases due to requiring direct communication protocols between devices
Solution Approach 1:
The patent implements a universal synchronization protocol that enables any peer device to communicate with any other peer device using the same standardized interface. This multi-functional approach allows a single protocol to handle various synchronization scenarios (direct peer-to-peer, indirect through intermediaries, group synchronizations) without requiring device-specific implementations, thereby improving ease of operation while controlling complexity through standardization.
Data Source
AI summary
An automatic synchronization method and apparatus that synchronizes data on a peer-to-peer basis across multiple devices. Automatic synchronization occurs on one or more similar user devices from one device to another and does not require synchronization with a central server. No single device acts as a central synchronization server, but all devices on which the application resides and that have the data to be synchronized can communicate with each other directly, or indirectly through other devices that have direct communication with the device on which data is changed.
