Data Synchronization Server Metadata Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data synchronization methods for mobile terminals are limited in migrating user data across platforms, resulting in high costs, complex operations, and time-consuming processes, as they only synchronize fundamental data, fail to accommodate multimedia and platform-specific content, and consume significant data and battery power, leading to a degraded user experience.
Innovation Solution
A data synchronization method and system that uses a data synchronization server to determine the source of digital contents based on summary information, reducing data backup by storing only metadata or storage location information, allowing for efficient migration and adaptation of digital contents across terminals, thereby reducing communication costs and network resource burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all digital contents are synchronized between terminals, then data completeness is improved, but network bandwidth consumption and battery power consumption increase significantly
Solution Approach 1:
The patent extracts only the essential identification information (URL, hash value, file name) from the complete digital content for synchronization. Instead of transferring entire files, the system synchronizes minimal metadata that uniquely identifies the content, allowing terminals to retrieve full content from remote servers when needed, thereby dramatically reducing power consumption while maintaining data completeness.
Solution Approach 2:
The patent segments the data synchronization process into two parts: (1) synchronization of lightweight identification metadata, and (2) on-demand retrieval of full content from remote servers. This segmentation allows the system to maintain data completeness while minimizing the energy-intensive wireless transmission and local storage operations.
2Loss of information
If all digital contents are synchronized between terminals, then data completeness is improved, but network bandwidth consumption increases significantly
Solution Approach 1:
The patent extracts only the essential identification information (URL, hash value, file name) from the complete digital content for synchronization. Instead of transferring entire files, the system synchronizes minimal metadata that uniquely identifies the content, allowing terminals to retrieve full content from remote servers when needed, thereby dramatically reducing network bandwidth consumption while maintaining data completeness.
3Reliability
If complete digital contents are stored on terminals, then data availability is improved, but terminal storage space requirements increase
Solution Approach 1:
The patent extracts and synchronizes only identification metadata (URL, hash value, file name) rather than complete digital content. This allows terminals to maintain data availability by storing minimal metadata locally while relying on remote servers for actual content storage, dramatically reducing terminal storage space requirements.
4Adaptability or versatility
If user data is synchronized across different terminal platforms, then platform compatibility is improved, but data format conversion complexity increases
Solution Approach 1:
The patent implements a universal identification scheme using standardized metadata fields (URL, hash value, file name) that can represent any digital content across different platforms. This universal approach eliminates the need for platform-specific format conversions, as the identification metadata remains consistent while the actual content is retrieved from its original source in its native format.
5Quantity of substance
If fundamental information only is synchronized, then network resource consumption is reduced, but user experience deteriorates due to loss of multimedia and platform-specific content
Solution Approach 1:
The patent extracts comprehensive identification metadata including URL, hash value, and file name for all digital content types (multimedia, platform-specific content, applications), not just fundamental information. This allows the system to synchronize minimal data while maintaining complete user experience by enabling retrieval of all content types from their sources.

AI summary
Disclosed are a data synchronization method, system, data synchronization server and terminal. A synchronization server determines the source of corresponding digital content according to the brief information uploaded by a user, and determines, according to the source of the digital content, to store the brief information only or further store the storage position information of the digital content or the digital content itself, thus reducing the data traffic for data backup, simplifying data migration difficulty when the user replaces a terminal, and reducing the communication cost of the user and the network resource pressure of a carrier.
