Evolutionary programming approach for securing medical images using genetic algorithm and standard deviation
The integrity and security of medical data have become a big challenge for healthcare services applications. Images of hidden text represent
steganography forms in which the image is exploited as an object to cover
information and data. So, the…

Enhancing of coverless image steganography capacity based on image block features
The idea of coverless information hiding has seen a great deal of development since it was initially introduced due to its effectiveness in
defeating steganalysis tools. However, the capacity for general coverless
information hiding methods to…
