A Survey on Digital Image Steganography and Steganalysis

Currently, there is a dramatic development ion aspects such as the verbal exchange of data, as well as computer-related technology. This trend has attracted growing scholarly attention, with the aspects of data protection also linked to dramatic growth in the interest of many scholars. For more than a decade, improvements have been felt in certain notable fields. They include steganalysis and steganography. Indeed, these attributes are important because they lend support to and gain application in areas such as national security, intelligence, and commercial enterprise. The aim of the current study lies in the enhancement of the attributes of steganalysis and steganography relative to image analysis, from the perspective of the pixel block-based totally adaptive steganography. The study considers several multi-decision decomposition processes and standards governing the steganalysis of images. It is also worth highlighting that the study demonstrates that through the least large beat, the matching process via the steganalysis procedure is capable of and yields superior outcomes relative to message embedment in single pixels. Indeed, the factor of images’ texture distribution does not play a significant role in hampering the aforementioned ability, if any. Overall, it is concluded that compared to flat regions, the attribute of image texture exhibits more structural randomness. Hence, hidden image embedment is more secure when high textures are involved.

A minimal description of morphological hierarchy in two-dimensional aggregates

A single dimensionless parameter is proposed to characterise the morphology of two-dimensional aggregates by their structural randomness.
