Partial Virtual Object Rendering for Digital Asset Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality, there is a challenge in safeguarding virtual assets from illegal copying, counterfeiting, and unauthorized use, as well as maintaining consistent ownership and rendering across multiple devices, due to the distributed nature of the VR world.
Innovation Solution
A method and system for rendering virtual objects in a multi-user system, where a partially rendered model of a restricted virtual object is sent to user devices, indicating the desired item, and can be fully rendered by users with permission, ensuring restricted content is only accessible to authorized users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fully rendered virtual object is made accessible to all users in a multi-user system, then visibility and accessibility of the object is improved, but security and protection of restricted content deteriorates
Solution Approach 1:
The virtual object model is segmented into two distinct versions: a partially rendered model visible to all users and a fully rendered model accessible only to authorized users. This segmentation allows the object to be universally visible while protecting restricted content from unauthorized access.
Solution Approach 2:
The partially rendered model acts as an intermediary between the fully rendered model and unauthorized users. It provides sufficient visual information for users to identify and desire the object without exposing restricted content, thereby mediating between accessibility and security requirements.
2Object-affected harmful factors
If a partially rendered model is used to indicate desired items, then security of restricted content is improved, but completeness of object information deteriorates
Solution Approach 1:
The system applies partial rendering by providing only the necessary visual information (partial action) to indicate the object's presence and identify it as desired, while withholding the complete rendering (full action) until authorization is verified. This partial action is sufficient for the specific goal of indicating desire without compromising security.
3Ease of operation
If restricted content is fully rendered for authorized users, then user experience and accessibility for authorized users is improved, but risk of unauthorized copying and counterfeiting increases
Solution Approach 1:
The system creates a visual copy (partially rendered model) that replicates sufficient characteristics of the virtual object to enable identification and desire indication, while deliberately omitting restricted content. This copy is distributed widely without compromising the original restricted content's security.

AI summary
Embodiments relate to receiving an indication of a desired item by a user in a multi-use virtual world. The indication requests a rendering of a restricted virtual object in a space of the user. A server can determine and retrieve a partially rendered model of the restricted virtual object, determine a rendering location based on position data, and link the partially rendered model to the user and to the rendering location. The partially rendered model and the rendering location can be sent to user devices for rendering the partially rendered model at the rendering location. A partially rendered appearance of the restricted virtual object indicates to a second user the desired item by a first user. A fully rendered model may contain restricted content data, whereas a partially rendered model may not contain restricted content data. The restricted content data may include a restricted digital media file.
