“…The creation information and logo of a creator are embedded in an electronic file in the form of unaware watermark which cannot be removed during sharing, and the watermark can be detected by a special software package [11,12]. Various watermarking methods were developed for the intellectual property protection of 2D/ 3D CAD models [13][14][15][16][17][18][19][20][21][22][23]. However, in a CPD environment, CAD models are needed to be shared safely, and watermark is not appropriate for sharing design information (design knowledge, parameters and so on) in a secure means.…”

Abstract. Model security for collaborative product development in a networked environment (or called networked manufacturing, grid manufacturing, and cloud manufacturing) is an important and also challenging research issue. An encryption based partial sharing approach for CAD models has been developed and presented in this paper. First, a random invertible decimal matrix to support the encryption approach is proposed, with which parts of a CAD model can be selected flexibly by the model owner for encrypting by different keys; Second, in order to guarantee the security, a dual-key mode and a key based authorization mechanism are proposed. Based on the model, different levels of security are achieved based on different key spaces, and the key based authorization mechanism is used for the model owner to control the partial access of the CAD model flexibly.

“…In the first article on 3D model watermarking in 1997 Ohbuchi et al (1997b), one solution to the localization problem called indexed localization was given, and this has also been employed by many later 3D model watermarking algorithms such as Yeo and Yeung (1999); Benedens and Busch (2000); Benedens (2000); Cayre et al (2004); Chou and Tseng (2006); Wang and Hu (2009). Methods of this kind divide the watermark into several parts, give each part of the watermark a subscript, and embed each part the of watermark together with its subscript and a marker.…”

Watermarking algorithms provide a way of hiding or embedding some bits of information in a watermark. In the case of watermarking a 3D model, many algorithms employ a so-called indexed localization scheme. In this paper, we propose an optimization framework with two new steps for such watermarking algorithms to improve their capacity and invisibility. The first step is to find an optimal layout of invariant units to improve capacity. The second step is to rearrange the correspondence between the watermark units and the invariant units to improve invisibility. Experimental tests show that by using this framework, the capacity and invisibility of watermarking algorithms can be greatly improved.

“…They also proposed a more controllable modification scheme with a better attack localization capability. Chou and Tseng [9] solved the causality problem by introducing the adjusting vertex method. In their watermarking algorithm, vertex is accurately controlled so that severe distortions, which are possible in [7], [8], are avoided.…”

Three-dimensional meshes have been used more and more in industrial, medical and entertainment applications during the last decade. Many researchers, from both the academic and the industrial sectors, have become aware of their intellectual property protection and authentication problems arising with their increasing use. This paper gives a comprehensive survey on 3D mesh watermarking, which is considered an effective solution to the above two emerging problems. Our survey covers an introduction to the relevant state of the art, an attack-centric investigation, and a list of existing problems and potential solutions. First, the particular difficulties encountered while applying watermarking on 3D meshes are discussed, followed by a presentation and an analysis of the existing algorithms, distinguishing them between fragile techniques and robust techniques. Since the attacks play an important role in the design of 3D mesh watermarking algorithms, we also provide an attack-centric viewpoint of this state of the art. Finally, some future working directions are pointed out especially on the ways of devising robust and blind algorithms and on some new probably promising watermarking feature spaces.
