Cloud Server Digital Resource Duplication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital resource duplication methods lack control over illegitimate duplication and are inefficient in circulating resources across different operating platforms.
Innovation Solution
A cloud server-based method that receives duplication requests, determines user rights, embeds identifiers in digital resource copies, and manages copy distribution across terminals, ensuring legitimate duplication and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital resources are duplicated without control mechanisms, then resource circulation and transmission among terminals is enabled, but illegitimate duplication cannot be prevented
Solution Approach 1:
The patent introduces a cloud server as an intermediary between the digital resource source and terminal devices. The cloud server receives duplication requests, verifies user rights, and manages copy distribution. This intermediary mechanism enables legitimate resource circulation while preventing illegitimate duplication through centralized control and authentication.
Solution Approach 2:
The system implements feedback mechanisms where the cloud server tracks the number of copies distributed and monitors terminal identifiers. When a duplication request is received, the system checks against recorded information to verify legitimacy. This feedback loop ensures that duplication remains controlled and prevents unauthorized copying while maintaining resource availability.
2Reliability
If cloud server control mechanisms are implemented for duplication, then illegitimate duplication is prevented, but system complexity increases
Solution Approach 1:
The cloud server automatically processes duplication requests by embedding unique terminal identifiers and identification information directly into the digital resource copies. The system self-manages copy tracking and verification without requiring complex external authentication infrastructure. This automation reduces operational complexity while maintaining security.
Solution Approach 2:
The cloud server performs multiple functions within a single system: it stores digital resources, processes duplication requests, verifies user rights, tracks copy distribution, and manages terminal registrations. This multi-functionality consolidates what could be separate complex systems into a unified platform, reducing overall system complexity.
3Measurement precision
If unique identifiers are embedded in digital resource copies, then copy tracking and control is enabled, but processing time increases
Solution Approach 1:
The cloud server pre-generates and stores unique terminal identifiers and identification information before duplication requests are made. When a duplication request arrives, the system simply retrieves and embeds these pre-prepared identifiers rather than generating them in real-time. This preliminary preparation significantly reduces processing time while maintaining accurate copy tracking.

AI summary
In a digital resource duplication method, the cloud server executes: a receiving step, for receiving a duplication request for a digital resource submitted by a resource requester, the duplication request comprising the identification information of the resource requester, the unique resource copy identifier, and the unique terminal identifier; a determination step, for determining, on the basis of the identification information, whether the resource requester is allowed to duplicate via the terminal a copy of the digital resource corresponding to the unique resource copy identifier; a transmitting step, for transmitting the copy to the terminal after embedding the unique terminal identifier and the identification information in the copy, when a determination result of the determination step is positive. The present invention can prevent the digital resource from being duplicated from a legitimate terminal to an illegitimate terminal for use, thereby effectively controlling the illegal duplication of digital resources between terminals.
