A Noble Authentication Model Using SHA3-512 Hash Function and 8-Directional Pixel Selection Technique of LSB Based Image Steganography

Abstract

In this paper we represent the web-based authentication security system which uses Image Steganography and SHA3-512 hashing function. Our developed web authentication system encrypts user’s password with SHA3-512 hashing function which hides into a cover image is called image steganography. Pixel selection for data hiding becomes crucial for the solutions in spatial domain of image steganography to ensure imperceptibility. This paper also presents an efficient approach of pixel selection technique for hiding secret data in cover object of image steganography. After reviewing recent literature, it has been observed that most of the works on pixel selection uses zig-zag technique for their solution. However, it becomes very prone to steganalysis based attacks by the intruders. In this study, 8- directions pixel selection technique is proposed to embed data in the cover image where Least Significant Bit (LSB) method has been used on Red, Green and Blue (RGB) color image especially focused on JPG, JPEG, and PNG. Since this projected procedure avoids the known steganalysis techniques, it will be challenging for the attacker to recognize the presence of secret information from the stego image. To measure the quality, statistical analysis has been performed where the value of the quality measurement matrices has provided better results. We endorse this security for forthcoming web applications of the future that will be handling subtle user information.
