3D Model Data Distribution Server Authorization Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for distributing three-dimensional model data over a network lack control mechanisms to ensure secure and effective transmission, particularly regarding ownership and authorization of the data generation equipment.
Innovation Solution
A three-dimensional data distribution system that includes a 3D model management server controlling the transmission of 3D model data based on whether the requesting application's company is identical to the company possessing the 3D scanner used for data generation, ensuring secure and authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If three-dimensional model data is distributed freely over a network, then accessibility and ease of operation are improved, but data security and reliability deteriorate due to unauthorized access and misuse
Solution Approach 1:
A server acts as an intermediary between the 3D scanner and external devices. The server receives 3D model data from the scanner, manages it securely, and controls distribution to authorized applications. This intermediary mechanism enables free network accessibility while maintaining data security through centralized authorization management.
Solution Approach 2:
The system implements self-service authentication where applications automatically verify their authorization status with the server before accessing 3D model data. The server autonomously manages authorization records and controls data distribution without requiring manual intervention, balancing accessibility with security.
2Reliability
If transmission control based on company identification is implemented, then data security and reliability are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The system uses company identification information as a copyable and transmittable attribute embedded in authorization records. Instead of complex verification mechanisms, the server simply compares company ID copies from the requesting application with the registered company ID of the scanner owner, simplifying the control mechanism while ensuring security.
Solution Approach 2:
The authorization control is based on changing the parameter of company identification matching. The server controls data transmission by verifying whether the company ID parameter of the requesting application matches the company ID parameter of the scanner owner, providing a simple yet effective security mechanism.
3Reliability
If company identification verification is performed before data transmission, then data integrity and reliability are improved, but transmission speed and productivity decrease
Solution Approach 1:
Company identification verification and authorization checks are performed in advance before 3D model data generation or storage. The server pre-establishes authorization records linking company IDs, so that during data transmission, only a simple record lookup is needed rather than complex real-time verification, minimizing transmission delays.
Solution Approach 2:
The system performs only the essential company ID matching verification without excessive checking. The server verifies the critical parameter (company ID match) and proceeds with transmission if authorized, avoiding unnecessary delays while ensuring data integrity through the essential verification step.

AI summary
A three-dimensional data distribution device includes: a communication unit that receives a transmission request, the transmission request being transmitted in accordance with a predetermined application and requesting transmission of three-dimensional model data, the three-dimensional model data indicating a three-dimensional shape of an object; and a controller that controls the transmission of the three-dimensional model data. The controller makes, based on the transmission request, at least one of a determination as to whether a first company is identical to a second company and a determination as to whether the first company has a partnership with the second company, the first company providing the predetermined application, the second company providing an equipment that has been used to generate the three-dimensional model data, and the controller controls the transmission of the three-dimensional model data in accordance with a result of the at least one of the determinations.
