New Patent: Authenticating 3D Structures

A new European patent, EP 3 374 975 B1, protects a method for authenticating a 3D structure by scanning it with a 2D image. Developed by AlpVision and marketed as SmartEmbossing, this technology allows three-dimensional structures to be authenticated using regular smartphones. SmartEmbossing utilizes standard industrial methods like hot foil stamping, providing a decorative effect without additional costs compared to traditional embossing methods. The authentication process employs sophisticated signal processing algorithms to exploit the underlying 3D structure using several images captured from different angles.
