3D Coverless Image Steganography Scheme Based on 3D Slice Technology

Abstract

Due to the property that coverless image steganography can hide secret information without modifying the carrier, it has the ability to resist the existing steganalysis tools effectively. However, with the continuous development of new media and the increasing complexity of application scenarios, finding a more se-cure means of covert communication has become an urgent problem. In this paper, we propose a 3D coverless image steganography (3D-CIS) method. Based on the properties of 3D image and the relationship between 2D image and 3D image, the 2D-CIS method is applied to 3D image. Using 3D image as the carrier not only enriches the data types of steganography, but also provides a more secure means of steganography communication. Specifically, this paper combined 3D image slice technology with the existing 2D-CIS scheme to achieve 3D image steganography, which is beneficial to improve the capacity and security performance of CIS technology and promote the development of coverless image steganography.
