In our present society, 3D objects play an increasingly important role in many different domains, especially with the development of meta environments. Many applications demand large 3D objects, which makes their compression a requirement. Meanwhile, 3D objects are also exposed to various security problems during online storage and transmission. Consequently, security aspects such as copyright and authentication are essential for 3D objects. In this paper, we propose a simultaneous 3D object watermarking and compression method based on Draco. A watermarking step is integrated within Draco, Google's 3D compression method, which is rapidly being universally adopted as standard. The proposed method enables a large bit embedding rate, which can be used for copyright information. The proposed method is also, to the best of our knowledge, the first watermarking method for 3D objects compressed with Draco.
