Comparing Original and Encrypted Sizes of Colorful Images by Steganography
2019
In today's digital world the secure and confidential data transmission by the various ways is quite vital.In order to avoid attacks which aim to receive data unauthorizedly, many different techniques have been developed by the years.In this paper one of these techniques called "image steganography" is analyzed.Ten colourful basic and popular images of image processing were used for the experiments.Also an image to hide in these ten images is chosen.The filtering algorithms is "mean filter algorithm".This filtered hidden image also has been hidden in these ten images.After that, the physical sizes of images were compared after encryption process.MATLAB program has been used for all these issues.
