Geometrically Encoded Metadata for 3D Model Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media file transfer techniques lose metadata information when converting 3D models between different formats, leading to unauthorized or lower quality content being used instead of original media, and potential legal issues due to improper distribution.
Innovation Solution
Implementing a geometrically encoded metadata structure that survives file conversion, allowing for the detection, restoration, and decoding of metadata within the media content, enabling automated validation of its authenticity and usage rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional media file transfer techniques are used for format conversion, then file conversion between different formats is achieved, but metadata information is lost
Solution Approach 1:
The patent embeds metadata within the 3D model structure itself, nesting the metadata inside the geometric data in a hierarchical manner. This allows metadata to travel with the model through format conversions just as the model geometry does, preventing information loss during adaptation to different formats
Solution Approach 2:
The patent introduces an intermediary metadata structure that acts as a bridge between the 3D model geometry and the conversion process. This intermediary structure carries metadata through the conversion pipeline, mediating between the source format and target format to preserve information that would otherwise be lost
2Reliability
If metadata is embedded in format-specific structures, then metadata can be stored with the media content, but metadata does not survive conversion to different formats
Solution Approach 1:
The patent creates a universal metadata structure that can function across multiple 3D model formats. The metadata is embedded in a format-agnostic manner within the geometry, allowing it to be read and interpreted regardless of the specific file format, thus achieving both preservation and compatibility
3Ease of operation
If no metadata validation is implemented, then media content can be freely distributed and used, but unauthorized or lower quality content may be used in place of original media
Solution Approach 1:
The patent embeds metadata including authentication information and quality markers into the 3D model before distribution. This preliminary action ensures that validation information is already present in the content, allowing receiving systems to verify authenticity and quality without requiring complex external validation processes
Solution Approach 2:
The patent implements a feedback mechanism where metadata about the content's origin, quality, and authorization is embedded and can be read back by receiving systems. This feedback loop allows automated verification of content authenticity and quality, enabling systems to reject unauthorized or low-quality content while maintaining ease of distribution

AI summary
According to one implementation, a system for validating media content includes a computing platform having a hardware processor and a system memory storing a media content validation software code. The hardware processor is configured to execute the media content validation software code to search the media content for a geometrically encoded metadata structure. When the geometrically encoded metadata structure is detected, the hardware processor is further configured to execute the media content validation software code to identify an original three-dimensional (3D) geometry of the detected geometrically encoded metadata structure, to extract metadata from the detected geometrically encoded metadata structure, decode the metadata extracted from the detected geometrically encoded metadata structure based on the identified original 3D geometry, and obtain a validation status of the media content based on the decoded metadata.
