Detection of counterfeit virtual objects

A computer-implemented method to detect counterfeit virtual three-dimensional (3D) objects, the method comprising:

• receiving a 3D mesh of an unauthenticated virtual 3D object;
• determining a plurality of two-dimensional (2D) views of the unauthenticated virtual 3D object, wherein each view of the plurality of 2D views is a rendered view of the 3D mesh of the unauthenticated virtual 3D object captured from a respective viewpoint;
• calculating a hash value for each 2D view of the plurality of 2D views;
• determining a plurality of distance values, wherein each distance value is indicative of distance between a respective hash value of a 2D view of the plurality of 2D views and a hash value of a corresponding 2D view of an authentic virtual 3D object;
• determining an aggregate distance value based on the plurality of distance values;
• and
• classifying the unauthenticated virtual 3D object as a counterfeit 3D object if the aggregate distance value meets a predetermined threshold distance value.

A non-transitory computer-readable medium comprising instructions that, responsive to execution by a processing device, causes the processing device to perform operations comprising:

• receiving a 3D mesh of an unauthenticated virtual 3D object;
• determining a plurality of two-dimensional (2D) views of the unauthenticated virtual 3D object, wherein each view of the plurality of 2D views is a rendered view of the 3D mesh of the unauthenticated virtual 3D object captured from a respective viewpoint;
• calculating a hash value for each 2D view of the plurality of 2D views;
• determining a plurality of distance values, wherein each distance value is indicative of distance between a respective hash value of a 2D view of the plurality of 2D views and a hash value of a corresponding 2D view of an authentic virtual 3D object;
• determining an aggregate distance value based on the plurality of distance values;
• and
• classifying the unauthenticated virtual 3D object as a counterfeit 3D object if the aggregate distance value meets a predetermined threshold distance value.

A system comprising:

• a memory with instructions stored thereon;
• and
• a processing device, coupled to the memory, the processing device configured to access the memory and execute the instructions, wherein the instructions cause the processing device to perform operations including:
• receiving a 3D mesh of an unauthenticated virtual 3D object;
• determining a plurality of two-dimensional (2D) views of the unauthenticated virtual 3D object, wherein each 2D view of the plurality of 2D views is a rendered view of the 3D mesh of the unauthenticated virtual 3D object captured from a respective viewpoint;
• calculating a hash value for each 2D view of the plurality of 2D views;
• determining whether the respective hash values of at least two 2D views of the plurality of 2D views of the unauthenticated virtual 3D object match hash values of corresponding 2D views of an authentic virtual 3D object;
• and
• if it is determined that the respective hash values match, classifying the unauthenticated virtual 3D object as a counterfeit 3D object.
