Efficient Data Hiding System Using Image Steganography

Image steganography is the art of concealing secret data within an image so that hackers cannot detect the information within the stego images. This is a useful method to protect sensitive information. In this paper, we focus on two techniques for hiding information in images. Firstly, we analyze the Least Significant Bit (LSB) method for storing information bits. However, this method is well-known, and attackers can easily reveal the information, making image steganography unsecured. Secondly, we propose to use R-Colour Channel encoding with the RSA algorithm to provide extra protection to information. Our approach uses a red color channel to hide information bits and the following bits for RGB pixel values of the original image. This project aims to present the performance analysis of the two most popular algorithms, LSB and RSA, along with image steganography.
