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 compression is an important part of information security because compressed data is
more secure and easy to handle. Effective data compression technology creates efficient …

Steganography is the art and science of hidden (or covered) communication. In digital
steganography, the bits of image, video, audio and text files are tweaked to represent 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 …

In the recent couple of years, due to the accelerated popularity of the internet, various
organizations such as government offices, military, private companies, etc. use different …

Digital steganography is the science of establishing hidden communication on electronics;
the aim is to transmit a secret message to a particular recipient using unsuspicious carriers …

In order to improve the security of images exchanged in telemedicine, we propose in this
paper, 2 watermarking schemes for retinal image protection; each scheme will be declined …

One of the highest priorities in the era of information technology is to achieve an accurate
and effective system for hiding security data. One of the goals of steganography is …

This paper discusses compression methods focused on data transmission over
communication channels. The characteristics of different algorithms for different types of …

The restricted devices have a small memory, simple processor, and limited power. To secure
them, we need lightweight cryptography algorithms, taking into account the limited …
