| Our work provides algorithms for encoding into a digital 3D object information that enables determining genuinity of a physical object after its automated manufacturing. In today's technological world, many physical objects are manufactured using 3D computer graphics models and digitally controlled devices (e.g., milling machines, 3D printers, and robotic arms). The manufactured objects can range from inexpensive steel screws to costly and carefully designed parts, for example, for engines and for medical instruments. Our algorithms provide a way to encode a unique signature into a computer-designed and fabricated object and a way to decode the signature in order to verify object genuinity. |
