Detection of protected subject matter in three dimensional print media
A contemplated system analyzes files used to create 3D objects by first virtually constructing the 3D object, and then by examining the virtual construct in a variety of different ways to determine if the 3D object has protected content. The system could examine the virtualized object from a variety of different angles, read characters embossed or imprinted upon the 3D object, and could even play virtualized records and other virtualized video/audio tools to determine if the 3D object has protected content. If the system rules that the 3D object has a high probability of having protected content, an alert is sent to an appropriate authority.
1. A method of analyzing a file containing instructions to print a three-dimensional object, comprising the steps of
saving the file in a memory;
executing instructions on a processor to virtually print a virtualized representation of the three-dimensional object within a virtualized Euclidian space using voxels to create the virtualized representation;
constructing a virtualized first two-dimensional representation of the virtualized three-dimensional object;
constructing a virtualized second two-dimensional representation of the virtualized three-dimensional object, wherein the first two-dimensional representation is different from the second two-dimensional representation;
analyzing the first and second two-dimensional representations to detect a protected subject matter; and
sending an alert when the protected subject matter is detected within at least one of the first two-dimensional representation and the second two-dimensional representation.
2. The method of claim 1 , wherein the file is at least one of a CAD file, STL file, VRML file, OBJ file, 3DS file, MAX file, and PRJ file.
3. The method of claim 1 , wherein constructing the virtualized first two-dimensional representation comprises creating an image of the virtualized three-dimensional object from a viewing angle of a first exterior surface of the virtualized three-dimensional object, and wherein constructing the virtualized second two-dimensional representation comprises creating an image of the virtualized three-dimensional object from a viewing angle of a second exterior surface of the virtualized three-dimensional object.
4. The method of claim 1 , wherein constructing the virtualized first two-dimensional representation comprises constructing an unfolded representation of a curved surface of the virtualized three-dimensional object.
5. The method of claim 1 , wherein constructing the virtualized first two-dimensional representation comprises merging a first flat surface of the virtualized three-dimensional object and a second flat surface of the virtualized three-dimensional object.
6. The method of claim 1 , wherein the step of analyzing the first and second two-dimensional representations further comprise:
determining whether at least one of the first and second two-dimensional representations could contain a visually unique component of the protected subject matter at an angle, wherein the visually unique component is detected upon a surface of the virtualized representation of the three-dimensional object; and
rotating a view of the virtualized representation of the three-dimensional object to display the visually unique component from a viewing angle that optimizes a similarity between the view and the protected subject matter.
7. The method of claim 6 , wherein the step of sending the alert comprises transmitting the optimized two-dimensional representation of the virtualized three-dimensional representation.
8. The method of claim 6 , wherein the alert is sent with the rotated two-dimensional representation.
9. The method of claim 1 , wherein the step of sending the alert comprises notifying an online service provider (OSP) of a potentially infringing act.
10. The method of claim 1 , further comprising analyzing metadata embedded within the file when the protected subject matter is detected.
11. The method of claim 10 , wherein the metadata comprises an identity of a distributor of the file.
12. The method of claim 10 , wherein the alert is sent with at least a portion of the metadata.
13. The method of claim 1 , wherein the protected subject matter is a copyrighted work.
14. The method of claim 1 , wherein the protected subject matter is a word mark.
15. The method of claim 1 , wherein the protected subject matter is a logo.
16. The method of claim 1 , wherein the step of analyzing the first and second two-dimensional representations to detect a protected subject matter comprises creating a text file that contains alphanumeric text detected within at least one of the first two-dimensional representation and the second two-dimensional representation.
17. The method of claim 1 , wherein the step of analyzing the first and second two-dimensional representations to detect a protected subject matter comprises determining a percentage likelihood of a similarity between at least one of the first and second two-dimensional representations and the protected subject matter, wherein the step of sending an alert is triggered when the percentage is above a threshold value.
18. The method of claim 1 , wherein the step of analyzing the first and second two-dimensional representations to detect a protected subject matter comprises:
determining a percentage likelihood of a similarity between at least one of the first and second two-dimensional representations and the protected subject matter; and
flagging the three-dimensional object for secondary review when the percentage is higher than a first threshold and lower than a second threshold.
19. The method of claim 1 , wherein the step of analyzing the first and second two-dimensional representations to detect a protected subject matter comprises detecting that a license term has been violated.
20. The method of claim 19 , wherein the step of sending an alert comprises notifying an authority that a distributor of the file violated the license term.
