A multilayered architecture for hiding executable files in 3D images


Steganography is a technique to hide secret messages in a host media called cover media. The advantage of steganography over cryptography is that messages do not attract attention to attackers and even receivers. Steganography and cryptography are often used together to ensure security of the secret messages. This paper introduces steganography work on 3D models. In this paper, we will exploit the geometric characteristics of 3D models to provide high-capacity data hiding. Capacity and invisibility are more important than robustness in the steganography system. Therefore, we aim at maximizing data hiding capacity while limiting distortion of cover models in a lower bounded value. A novel multilayered embedding scheme is proposed for enlarging the hiding capacity. In the extraction procedure, the embedding order can also be obtained using the secret key in the spatial analysis step. The payload can then be correctly extracted in this embedding order.
