Batch Zero-steganographic Model for Graph Transformation

چکیده
To further improve the security of digital image steganography, based on graph transformation diversity, proposed a zero-steganographic model. After divided into many blocks, the secret information is deduced by graphic transform algorithm, and a cover image steganographic model for not carrying secret information is constructed. First step is selecting a batch of cover images through a particular transformation algorithm for them, and then find out the correlation of pixels between secret images and the new images, finally return to its original for transmission. Extracting secret information only to need the key without carrier images, further improve the security of secret information. Experimental results and analysis show that this model confidential is strong, the security is good, and applies to images concealed communication.

Model checking is an automatic technique for software verification through which all reachable states are generated from an initial state to finding errors and desirable patterns. In the model checking approach, the behavior and structure of system should be modeled. Graph transformation system is a graphical formal modeling language to specify and model the system. However, modeling of large s...
متن کاملENTROPY OF DYNAMICAL SYSTEMS ON WEIGHTS OF A GRAPH
Let $G$ be a finite simple graph whose vertices and edges are weighted by two functions. In this paper we shall define and calculate entropy of a dynamical system on weights of the graph $G$, by using the weights of vertices and edges of $G$. We examine the conditions under which entropy of the dynamical system is zero, possitive or $+infty$. At the end it is shown that, for $rin [0,+infty]$, t...

The batch steganography problem is how best to split a steganographic payload between multiple covers. This paper makes some progress towards an information-theoretic analysis of batch steganography by describing a novel mathematical abstraction we call perturbation hiding. As well as providing a new challenge for information hiding research, it brings into focus the information asymmetry in st...
متن کاملA Simply Study to Steganography on Social Networks
Steganography aims to conceal the very fact that the communication takes place, by embedding a message into a digit object such as image without introducing noticeable artifacts. A number of steganographic systems have been developed in past years, most of which, however, are confined to the laboratory conditions where the real-world use of steganography are rarely concerned. In this paper, we ...
متن کاملProperties of extended ideal based zero divisor graph of a commutative ring
This paper deals with some results concerning the notion of extended ideal based zero divisor graph $overline Gamma_I(R)$ for an ideal $I$ of a commutative ring $R$ and characterize its bipartite graph. Also, we study the properties of an annihilator of $overline Gamma_I(R)$.
