Robust watermarking scheme using Weber Law for 3D mesh models

Authentication and identification of multimedia objects play an important aspect for multimedia security. In this we present a semi-blind watermarking scheme for 3D mesh models using Weber’s law. A robust and imperceptible spectral watermarking for high rate embedding of a watermark into 3D polygonal meshes is analyzed in this paper. The proposed approach consists of these main steps (i) mesh is portioned into smaller sub-meshes, (ii) generation of watermark from the original model, (iii) watermark embedding and extraction to each sub-meshes. Extensive experimental results show an improved performance of the proposed system and also its robustness against the most common attacks including the geometric transformations, adaptive random noise, mesh smoothening, mesh cropping and combination of these attacks.
