Steganography
In most of the digital steganography methods provided for natural digital images, the
embedding of the confidential message is based on the minimisation of the defined distortion
functions. It is often done based on choosing the most optimal criterion of distortion.
Although the distortion functions are designed innovatively, steganography algorithms will
be optimal. In such approaches, embedding interactions are often overlooked. Unlike usual
images that have areas with a variety of tissue features, there are many smooth areas inmedical
images that will make the changes more visible if they are manipulated. Therefore, this
study presents an adaptive approach that comes from the interactions between the changes
made during the embedding algorithm to reduce the probability of recognising themessage
embedded in medical images and reducing the distortion caused by embedding in a discrete
cosine transform space and based on the imperialist competitive algorithm for joint photographic
experts group images, especially in medical images due to the importance of
information steganography in them. The results obtained show the high efficiency of the
proposed algorithm in comparison with the state-of-the-art methods that are presented in
this area.
