Abstract

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.

Background

BACKGROUND (1) Media content including three-dimensional (3D) data structures, such as 3D models, for example, tend to lose metadata information when utilized in model manipulation software applications. This is because conventional media file transfer techniques rely on format-specific metadata that does not survive conversion to a different format. For example, a 3D model formatted for AUTOCAD® will typically lose all metadata information when converted to virtual reality (VR), 3D printing, or animation formats. (2) The metadata lost during file conversion may identify the author of the media content, its version, its owners and/or licensees, its storage and transfer history, and other information determining its chain-of-custody, validity, and eligibility for use in movies, television, or Internet based distribution. Without that metadata information, unauthorized or lower quality content may inadvertently be used in place of original media content or authorized copies of that original content approved for use. Moreover, media content approved for distribution through some channels but not others may be improperly distributed in violation of contractual agreement, thereby subjecting the content distributor to legal jeopardy. SUMMARY (3) There are provided systems and methods for validating media content using geometrically encoded metadata, substantially as shown in and/or described in connection with at least one of the figures, and as set forth more completely in the cla

Claims

1. A system for validating a media content including a three-dimensional (3D) data structure, the system comprising: a computing platform including a hardware processor and a system memory; a media content validation software code stored in the system memory; the hardware processor configured to execute the media content validation software code to: detect a geometrically encoded metadata structure contained in the 3D data structure of the media content, wherein the 3D data structure and the geometrically encoded metadata structure are deformed; restore an original 3D geometry of the geometrically encoded metadata structure; extract a metadata from the geometrically encoded metadata structure; decode the metadata based on the original 3D geometry to obtain decoded metadata; and obtain a validation status of the media content based on the decoded metadata. || 9. A method for use by a system for validating a media content including a three-dimensional (3D) data structure, the system including a computing platform having a hardware processor and a system memory storing a media content validation software code, the method comprising: detecting, by the media content validation software code executed by the hardware processor, a geometrically encoded metadata structure contained in the 3D data structure of the media content, wherein the 3D data structure and the geometrically encoded metadata structure are deformed; restoring, by the media content validation software code executed by the hardware processor, an original 3D geometry of the geometrically encoded metadata structure; extracting, by the media content validation software code executed by the hardware processor, metadata from the geometrically encoded metadata structure; decoding, by the media content validation software code executed by the hardware processor, the metadata based on the original 3D geometry to obtain decoded metadata; and obtaining, by the media content validation software code executed by the hardware processor, a validation status of the media content based on the decoded metadata.
