De-identified search of part designs

A computer-implemented method, comprising:

• accessing, by a server device operatively coupled to a processor, a part design file provided by a client device, wherein the part design file comprises a computer-aided design (CAD) geometry of a part;
• searching, by the server device, an historical database for a same or similar instance of the part, via performance of a multi-staged search, wherein the multi-staged search is based on a cryptographic hash of the part design file, is based on a spatial hash of the CAD geometry, and is based on an anonymized feature vector extracted from the CAD geometry;
• and
• returning, by the server device, to the client device, and in response to the multi-staged search, an electronic notification indicating whether the same or similar instance of the part was identified.

A computer program product for facilitating de-identified search of part designs, the computer program product comprising a non-transitory computer-readable memory having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• access a part design file provided by a client device, wherein the part design file comprises a computer-aided design (CAD) geometry of a part;
• search an historical database for a same or similar instance of the part, via performance of a multi-staged search, wherein the multi-staged search is based on a cryptographic hash of the part design file, is based on a spatial hash of the CAD geometry, and is based on an anonymized feature vector extracted from the CAD geometry;
• and
• return, to the client device and in response to the multi-staged search, an electronic notification indicating whether the same or similar instance of the part was identified.
