pp: 36-45
In this article, we introduce and investigate watermarking of 3D objects represented by polygonal models, and propose a new watermarking technique that enables the verification of 3D polygonal models for detecting unauthorized alterations. Our proposed technique consists of a watermark encoding process that embeds a sequence of data bits by perturbing coordinates of the vertices in a 3D model, and a watermark decoding process that extracts bit information from 3D geometry using secure verification keys.
