Multiple Level Information Security Using Image Steganography and Authentication

Amount of information which can be stored within the images, and the movement of images over open network takes to the problem of image theft and breach of confidentiality. To prevent the loss of information from images, it leads the idea of image encryption in which various researchers are trying to encrypt image in such a way that un-authorized users should not be able to access the information kept within image, and for the same purpose researchers have proposed different image encryption techniques with confusing features to keep the images secure when they are moving over open networks. So, in the chain of existing work, we are purposing an image encryption method which is using block formation within the image, and each block is then used in zigzag manner followed by interpixel displacement of RGB values within that zigzag area of the block. The block sizes can vary from image to image and this is part of the key.

Models and Methods of Corporate Information Protection System

Karimov¹

2020

This article examines the models and methods of protection of information security systems, in particular, the model of building a corporate information security system, the model of security analysis in the absence of intrusive threats in information systems and the three-tier model of information security systems. As a result of the analysis of corporate information protection systems, models and recommendations for improving the efficiency of the information protection system are proposed.

“…C. Y. Lin et al in [6] proposed an RST resilient watermarking scheme. In [8], Espina et al proposes a new multiple tier information security system using image steganography and authentication using digital signature. They could get a PSNR of 47.72dB.…”

An effective and robust approach of Image Cryptography using Phase Congruence Correlative method and Arnold Cat Map

2020

In this paper, an effective and robust method of image cryptography scheme is proposed using Phase Congruence Correlative (PCC) method and Arnold Cat Map (ACM). The secret image or a secret watermark is scrambled using ACM method. This scrambled secret image is then embedded into a host image using Adaptive α-β Blending method. The place of embedding in the host image is effectively obtained using PCC method. The embedded image is subjected to various attacks and the secret image is retrieved from the distorted embedded image. This retrieved secret image is compared with the original secret image and various parameters like Peak Signal to Noise Ratio (PSNR), Root Mean Square Error (RMSE), Absolute Difference (AD), Mean Absolute Error (MAE), Maximum Difference (MD) are obtained. This proposed method proves to provide better performance metrics over the past methods.
