Data hiding in digital images is a promising direction of cybersecurity. Digital steganography methods provide imperceptible transmission of secret data over an open communication channel. The information embedding efficiency depends on the embedding imperceptibility, capacity, and robustness. These quality criteria are mutually inverse, and the improvement of one indicator usually leads to the deterioration of ...

In the paper, we consider a particular direction of digital steganography — information embedding into the compressed JPEG images. A scheme of information embedding based on procedures of DCT-coefficients replacement is introduced. Variants of the scheme algorithmic implementation are offered and investigated. A genetic algorithm is used for the improvement of the embedding quality. The ...

Steganalysis of digital images includes creation of feature space, formation of learning selection and qualifier training. Some known steganalysis systems offered for practical use work in space with dimension in tens of thousands of features. Therefore researches directed to identification of the most informative features including indicating use when embedding concrete steganographic primitives are relevant. ...

The relevance. One of the areas of digital image processing, including images of Earth remote sensing, is associated with the embedding of additional information into such images for various purposes. Embedding of additional information into a digital image leads to distortion of the digital image natural model, as well as to the possible occurrence of visual ...
