Steganography by Constructing Marbling Texture

摘要

This paper proposes a novel steganographic method to hide secret data during the generation of marbling patterns. We select some points on white paper to represent secret information. These points are connected with lines to construct an original pattern. With a series of deformation operations, the original pattern is transformed to generate a marbling pattern. During the process of data hiding, we construct a unit library containing different deforming operations. The library records the parameters of each deformation, and defines the mapping between the binary data and the deformation type. The unit library is shared with the recipient so that the deformation parameters can be recovered correctly. After using reverse deformations, the recipient identifies the location of the inflection points and extracts the secret data. Experimental results show that the proposed method performs high security and flexible embedding capacity. Meanwhile, the marbling images have a good visual effect. Furthermore, the proposed steganography provides a capability of countering JPEG compression.
