TLDR
In this paper, an image steganography methodology is performed using MATLAB/Simulink and a brief analysis of various algorithms is done and a histogram is also plotted.Abstract:
With the advent of growing terrorism in the world and the availability of the internet, data integrity is being endangered. Hence ensuring the security of the messages is paramount. Steganography is used—the process of hiding information in image, video, etc. Steganography is not any novel technique, it had been used too earlier where they use to shave the head and embed the message on to it and then wait for the hair to grow in ancient Greece; it was also used in war times. The methodology carried out here is of least significant bit technique and random pixel technique. A brief analysis of various algorithms is done and a histogram is also plotted. The image steganography methodology is performed using MATLAB/Simulink. It is also vindicated as to where to hide the message in the image so that, it is barely noticed by any observer, keeping in view the quality, size, and resolution of the image.read more
