Distributed Component for Secure 3D Printing Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing technologies lack effective intellectual property protection for 3D model data, allowing for unauthorized copying and printing, as files become uncontrollable once downloaded to local devices.
Innovation Solution
A distributed component is generated for 3D printing tasks, containing decryption information, which controls the execution of the printing process independently of the information processing apparatus and is deployed to user equipment, ensuring secure transmission and protection of 3D model data through encryption and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3D model files are downloaded to local electronic devices for remote printing service, then printing accessibility is improved, but intellectual property protection deteriorates as files become uncontrollable and can be arbitrarily copied
Solution Approach 1:
The system segments the 3D model data into multiple encrypted fragments and distributes them across different nodes. The decryption information is separated from the model data itself, requiring both components to reconstruct the original model. This segmentation prevents complete unauthorized copying while maintaining printing accessibility through distributed storage and controlled decryption.
Solution Approach 2:
The patent introduces an intermediary printing control system that acts as a mediator between the stored encrypted model fragments and the 3D printer. This intermediary holds and manages the decryption information, controlling when and how the model data is reconstructed and printed. This prevents direct access to complete model files while enabling authorized printing operations.
2Extent of automation
If decryption information is embedded in distributed components for independent execution, then printing autonomy is improved, but security control complexity increases
Solution Approach 1:
The system performs preliminary encryption and fragmentation of 3D model data before distribution. Decryption information is pre-packaged into distributed components that can execute independently. This preliminary preparation enables autonomous printing operations without requiring real-time server intervention, while the pre-established security structure manages the complexity of controlling decryption access.
