An adaptive algorithm for the steganographic embedding information into the discrete Fourier transform phase spectrum
.
On the example of digital images there are investigated properties of the discrete Fourier transform (DFT) used to embed information into the phase spectrum. The investigation helped to form a new steganografic algorithm that can be used in case of non- compressed images. Peculiarity of the algorithm is changeable size of information put into the blocks of stego-image. Characteristics of the suggested algorithm are comparable with the analog ones, they allow to get the correct information without mistakes.

Using an attack-simulation module is a well-recognized approach to improving the robustness of end-to-end neural-network-based data-hiding schemes. However, most proposed attack simulators are limited in the types of attacks they cover, usually handling only a basic set of digital transformations. Real, in-demand use cases for data-hiding methods may involve modifications that cannot be modeled by ...

Watermarking is a key tool in combating unauthorized content distribution, but its effectiveness is often challenged by the wide range of communication channels that can degrade or remove the watermark. We propose a block neural network-based watermarking scheme for digital images that is robust against diverse transmission channels, including compression, pre-processing, and digital-to-analog conversions such ...

Invisible image watermarking is a promising method for protecting the copyright of digital images such as photographs, illustrations, and scans. An effective watermarking algorithm embeds a special mark into an image that does not change the image content but can be extracted from it even after some common post-processing operations such as cropping or compression. ...

Embedding additional information into digital images is an effective method of data privacy protection. A data hiding scheme needs to have a high level of imperceptibility to provide a high level of security. At the same time, it is necessary to maintain good capacity and ability to extract information in its original form. In this ...
