Computer-aided design (CAD) files have become one of the most valuable assets of engineers and experts in a great variety of fields, universities, and institutions all over the world. This means that they require protection from external threats like viruses or cybercriminals attempting to ‘hack’ the system.

The evolving and innovative 3D printing industry is a huge consumer of everything CAD has to offer since CAD systems enable designers and users to create prototypes, models, and more. However, the product design files could be at risk when being transferred from one user to another, which is why New York University researchers developed a system for converting CAD files to a frequency domain, allowing them to hide 3D designs in sound files and more, as well as letting people who receive the files extract specific design features in a way that is not feasible in the current CAD file formats.
