Watermarking of 3D models is one of hot research topics in the field of watermarking.The difficulties for 3D model watermarking are robustness and blind detection.To achieve robustness

implement blind detection and make the detection result unambiguous

this paper proposes a new blind 3D model watermarking algorithm for triangular meshes.The scheme embeds the watermark

which is readable character string rather than meaningless pseudo-sequence

by modifying the location of vertices in their local coordinate system.The original model is not required for detecting watermarks.Experimental results show that the algorithm has good visual quality and is resilient against attacks such as translation

rotation

scaling

model cropping and vertex permutation.
