Image Steganography: An Inevitable Need for Data Security

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.

Steganography algorithm based on public key cryptosystem

Abstract: Combine steganography techniques and the public key cryptosystem is new line to protect the transferring information. This paper presents a new method to hide the data into an image using RSA cryptosystem. Proposed algorithm is clarified in detail through the overall scenario and through concrete examples. The experiments on the proposed algorithm demon strated that it is a simple and efficient technique with a high level of security for transferring information. Accordingly, this proposed algorithm can be considered as a hybrid of steganography techniques and the public key cryptosystem and it can be used effectively for this purpose.
