This article is devoted to the study of the improved neighbor mean interpolation (INMI) steganographic method. To date, no steganalysis of such a method of information embedding has been carried out. We implemented the INMI method of embedding messag

In this article, we present a new stegoanalysis method for detecting a text obtained by the synonym Run-Length Encoding. The analyzed RLE-method allows us to keep some statistical properties of the text after a secret message embedding. In particular

In this article we present a new method of steganographic transformation of a binary message, which allows to embed secret data with minimal statistical distortion of the original message. The constructed algorithm should be applied before steganogra

In this article we present a new method of stegoanalysis revealing the text produced by the synonym runlength encoding steganography. During this research, it was shown that RLE embedding method changes statistical structure of extracted message and

In this paper we propose new attack on dynamic watermark scheme Radix-n widely known as one of the most secure. It was shown that we are able to reveal dynamically allocated memory blocks and then a digital watermark can be discovered by hooking API

In this paper we propose a new method for hidden messages transmission in social networks, on the example of the network “Vkontakte”. It was proposed to use a graph structure of user's friends to embed a secret message. It was tested for robustne
