Abstract

Aiming at the problem that most of the existing embedding carriers of information hiding are single two-dimensional images with limited embedding information capacity, a multicarrier information hiding algorithm based on hierarchical compression of 3D point cloud model is proposed. First, the minimum bounding box of the model is generated and the model slices are layered. Secondly, the carrier set is classified. Finally, the secret information is hidden. Experimental results show that the robustness of the proposed algorithm is significantly improved compared with the comparison algorithm when facing a single attack.
