The ocean model is the dynamic framework and core component of the ocean numerical prediction system. The marine model has been continuously developed since its birth in 1969. There are more than 40 ocean models, including different sea areas (ocean, offshore, nearshore, and harbor) and different marine disciplines (physical ocean, marine ecology, marine chemistry). The class analysis algorithm divides the vertices of the fused state model into energy, and obtains the vertices of different energies. Finally, the secret information of Arnold's scrambled change is quickly hidden by modifying the vertex coordinates. The secret information in the algorithm is hidden in multiple fused states and ocean 3D models, which is beneficial to the invisibility and robustness of the algorithm. Experimental results show that the proposed algorithm is robust against attacks against uneven compression and has high invisibility. This paper first analyses the convexity degree and Vertex coordinate modification of the ocean 3D model, and then it analyses the three-bit model algorithm for multi-fusion states in ocean applications. Finally, we provide a new 3D model information algorithm for multi-fusion ocean applications.
