Encrypted 3D Model Rendering for Non-Distributable File Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3-dimensional model files, such as STL files, are easily distributable and reproducible, allowing unauthorized copying and distribution, which compromises the security and control of the original design, particularly in medical and industrial applications where precise manufacturing is required.
Innovation Solution
A method involving data conversion, encryption, and encoding of 3-dimensional model files to create a non-distributable format, ensuring the files can only be viewed and manipulated within a controlled environment without the ability to replicate the model externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3-dimensional model files are made easily viewable and manipulatable in virtual environments, then the ease of operation is improved, but the security and control of the original design deteriorates due to unauthorized copying and distribution
Solution Approach 1:
The patent introduces an intermediary system consisting of a secure rendering platform and encrypted file format that mediates between the 3D model owner and the viewer. The model is converted into a proprietary encrypted format that can only be viewed and manipulated within the controlled software environment, preventing direct access to the original design files while still enabling full viewing and manipulation capabilities.
Solution Approach 2:
The patent creates a controlled copy of the 3D model in an encrypted format that functions for viewing and manipulation purposes but cannot be used for reproduction or manufacturing. This copy is made available to users through the secure platform, allowing them to work with the model without possessing the original distributable files.
2Reliability
If 3-dimensional model files are converted to encrypted non-distributable formats, then the security and control of the original design is improved, but the ease of operation deteriorates due to restricted access and viewing capabilities
Solution Approach 1:
The patent creates a universal secure viewing platform that can handle multiple encrypted 3D model files and perform various operations (viewing, manipulating, measuring, analyzing) within a single controlled environment. This multi-functional system ensures that while access is restricted, all necessary operational capabilities are available within the secure platform.
Solution Approach 2:
The patent changes the state of the 3D model files from unencrypted to encrypted format, and from distributable to non-distributable. This parameter change fundamentally alters the accessibility and security characteristics of the files while maintaining their functional utility within the controlled environment through the decryption and rendering system.
3Adaptability or versatility
If standard 3D model formats like STL are used for distribution, then the adaptability and versatility of the model are improved, but the loss of information increases due to unauthorized modification and replication
Solution Approach 1:
The patent segments the 3D model data into encrypted components that are rendered and processed within the secure platform. The model information is divided into visual representation data and proprietary definition data, with only the visual portion being accessible to users, thereby preventing extraction of complete design information while maintaining format adaptability for viewing purposes.
4Productivity
If 3-dimensional models are made available for virtual assessment and manipulation, then the productivity of the design review process is improved, but the harmful factors increase due to potential unauthorized distribution and replication
Solution Approach 1:
The patent converts the potential harm of file distribution into a benefit by implementing a controlled rendering system that allows full viewing and manipulation capabilities while preventing extraction and redistribution. The system transforms the risk of unauthorized access into a secure collaborative platform where productivity is enhanced without the danger of information leakage.
Data Source
AI summary
The disclosure relates to a method and system for storing, sharing, rendering, and simulation of 3-dimensional digital data models so that the model cannot be copied or distributed or physically replicated and thus maintain the security of the model. Protecting a file containing digital data of a 3-dimensional representation of an object suitable for reproduction by a 3-dimensional model-making device. A method comprises converting a digital data file representative of a 3-dimensional object by removing predetermined parts of the digital data file to create a converted digital data file and encrypting the converted digital data file using an encryption algorithm and encoding key to create an encrypted digital data file having a file format; and making available the converted and encrypted digital data file in the file format to a software environment, wherein the software environment is suitable for decrypting and reconstructing the digital data into digital data.
