Februrary 12, Center for Information Aagainst Inte We present an a priori estimate to determine the amount of data that can be hidden in the image while still being able to maintain frequency count based on statistics. This paper presents a new method to preserve the statistical properties of the cover medium.

Defending Against Statistical Steganalysis Abstract The main purpose of steganography is to hide the occurence of communication. These discrepancies defensing the fact that hidden communication is happening. About Deep Blue Data.

DEFENDING AGAINST STATISTICAL STEGANALYSIS PDF

Steganalysis techniques work on eliminating suspicion about the existence of a message. If suspicion is raised, then the message cannot be passed covertly. One of the ways to detect the hidden message is to view the statistical properties of the image or medium in which the message is hidden. This is called a statistical attack. In this paper, we explain the nature of such attacks and present our conclusions based on reviews of existing methods of defense against statistical attacks. Over the ages, it has developed into an art of hiding the very existence of a message when it is being relayed. Any code that can be represented digitally can act as a carrier for a message.

Volume: 1 Issue: 2 - first five bits of the header contain the size of the length field in bits and the remaining ones express the size of the embedded data. It uses a fixed table that defines classes of DCT coefficients to determine the order in which the coefficients are to be modified. In this technique, the next class is chosen only after the coefficients in the current class are used. This ensures information hiding in the class even after the entire message has been embedded.
