So, detecting text steganography is also simple one. The hidden characters, lines and extra spaces in a text file can be visible and it can be easily detected [2] 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.
