“…This procedure consists of modifying successively the parallel, vertical, and rotary positions of a vertex related to its opposite edge in a triangular face. To enhance the invisibility of their embedding method, Cheng and Wang [8] extended their high-capacity mesh watermarking algorithm. The basic idea is to use a new representation rearrangement procedure (RRP) that allows to adaptively embed more bits in rough regions of the mesh surface.…”

International audienceDigital watermarking can be used as data hiding technique to interleave cover content with auxiliary information before transmitting and storing applications. While image and video watermarking has been widely studied, much less attention has been paid to its application in 3D mesh models. This is principally due to their intrinsic irregular sampling nature. This paper proposes a high-capacity watermarking scheme for the purpose of inserting meta-data into 3D triangle meshes. Our proposal can be applied to meshes with arbitrary topology by using irregular wavelet-based analysis. The watermark is embedded in an appropriate resolution level by quantizing the norms of wavelet coefficient vectors. To ensure robustness to similarity transformation, a robust synchronization (indexing) mechanism is performed on the 3D model after irregular wavelet analysis. Experimental results show that our watermarking framework is robust to common geometric attacks and can provide relatively high data embedding rate whereas keep a relative lower distortion

“…They can be used simply to modify media content, but in so doing, they limit the capacity for and security of the hidden secrets. Currently, much content is transmitted through the Internet, and a fraction of it is made by computer animators, and includes text and simulated media [25][26][27][28][29][30][31][32]. Cayre and Macq [28] were the first to propose a data-hiding method that was based on 3D polygons.…”

This work proposes a new and non-blind steganographic scheme for synthesized pitches. Synthesized music is popularly used to demonstrate early versions of compositions conveniently and at low-cost. They can also be utilized to pass secrets or obtain digital rights. The method consists of two procedures, of which the first is the realistic simulation of synthesized pitches using a computer and the second is the hiding of secrets during the generated simulated pitches. The first part of this paper reviews attempts to discover the fundamental patterns of synthesized pitches and to develop a strategy for generating approximate pitches using a computer. The component frequencies are used to generate a pitch in which to hide secrets. Legal receivers receive the referenced composition and frequencies, enabling them to generate the synthesized pitches according to the main frequencies of the referenced composition. Finally, the generated and received pitches are compared to identify the secret bits. As more frequencies are used to hide secret bits, more secret bits can be embedded in the synthesized pitches. The use of more frequencies makes synthesized pitches more realistic compared to real ones. The performance of the proposed method is also compared with that of competing methods and under common attacks.

“…The goal is to maximize capacity while ensuring that the amount of hidden information can be transmitted without errors. 3D model watermarking technology has been actively studied in the past, but only a few works have addressed information hiding for covert communication [27], [28], [29]. In [27], the authors presented a blind information hiding scheme based on a substitution procedure in the spatial domain.…”

“…Steganography and cryptography are often used together to ensure security of the secret messages [33]. For example, many previous steganography approaches [27], [28], [29], [34] use the secret key (i.e., idea borrowed from cryptography) to produce better protection of the information if the stego object arouses suspicion. Therefore, these approaches can become more secure and can be potentially useful to some security-demanding applications such as military intelligence.…”

Abstract-In this paper, we present a very high-capacity and low-distortion 3D steganography scheme. Our steganography approach is based on a novel multilayered embedding scheme to hide secret messages in the vertices of 3D polygon models. Experimental results show that the cover model distortion is very small as the number of hiding layers ranges from 7 to 13 layers. To the best of our knowledge, this novel approach can provide much higher hiding capacity than other state-of-the-art approaches, while obeying the low distortion and security basic requirements for steganography on 3D models.
