Digital steganography has a long history, starting to be developed in the 90s until now. The
main aspects of early steganography are security, imperceptibility, and payload. Security is …

Data security can involve embedding hidden images, text, audio, or video files within other
media to prevent hackers from stealing encrypted data. Existing mechanisms suffer from a …

Secrete message protection has become a focal point of the network security domain due to
the problems of violating the network use policies and unauthorized access of the public …

Prediction-error expansion (PEE) is the most widely investigated reversible data hiding
(RDH) framework. However, the performance of PEE can be further improved since the …

In this work, we proposed a robust and blind watermarking approach to adequately secure
medical images exchanged in telemedicine. This approach ensures the traceability and …

It is essential to secure the information to store or transfer digital files without destruction.
Currently, all used e-data requests to be utilized in well-controlled, protected, and …

Nowadays, neural networks are actively used for data hiding; however, there is currently no
systematic knowledge regarding their utilization in this field. This is a significant gap …

To secure the heartbeat sound exchanged in telemedicine, we propose in this work a blind
watermarking approach combining a Non-Subsampled Shearlet Transform and Singular …

In recent years, the importance of information security has increased due to the growth in
digital communication and steganography has come to the fore for secure communication …

Pixel value differencing (PVD) steganography techniques produce imperceptible stego‐
images. Most PVD‐based techniques have a fall‐off boundary problem (FOBP). To avoid …
